Drafting ruler.

I'm from estonia.  Local stores don't sell much different items as in bigger countries. So i'm missing many good things to DIY.   I need drafting board with straight  up and down movable ruler. 100% straight lines can't be done only by hand and ruler.  I have particle board and some L and U brackets.  Idea is do make drafting board  like this http://i.ebayimg.com/00/s/MTA1NFgxNjAw/z/0dEAAOxyeR9TF7AP/$_57.JPG Problem is ruler. I haven't found right ruler mechanism from stores. I think I need to make mechanism for ruler. How? With  fishing line like this http://ep.yimg.com/ay/draftingsteals-store/para-liner-delux-parallel-straightedges-by-alvin-3.gif I have also seen rollers and fishing line on ruler.  Fishing line under the board is way more better than on the board.

custom ruler scriber

Years ago (before computers), I worked in a lab where we were called upon to make clear plastic rulers with precise increments.  We had a simple machine to accomplish the job. It was an ingenious gadget that held the plastic in place and with a turn of a crank, it moved the plastic a set distance and simultaneously scribed the plastic with a metal point.  The precise divisions could be set with a dial and all you had to do was turn the crank. Has anyone ever seen one of these machines?  If so - what is it called and how would you make one?

Need help to realize an idea: "Projector-Ruler"

Hello there, thanks for attention. I have an idea "Projector Ruler" ,which can show a ruler or other measuring tools on the wall, so that can help people to read the information of target easily. My concept have won international design awards, including Spark Design Award and IDEA. I think this idea is possible, potential ,and required by the market. You can see more detail in video or by following link: P-Ruler I plan to realize this concept. However, my study background can't enough support me to implement it. So, I need someone who understand the principle of projector, rangefinder or other related knowledge to help me to build this idea. I hope that we can group a team to generate it and co-found it. (The funds can come from Kickstarter :D). If you're interested, please contact me or make a comment. Thank you. P-Ruler from Chang Yu-Chung on Vimeo.

Calculating notes of twanged strips Answered

Consider a twanged metal ruler, or the "keys" of a thumb piano (kalimba)... I'm in the middle of designing A Thing, and I am sure that there ought to be a way of calculating the note produced when you twang the end of a strip of metal. Assuming I know the Young's modulus, length, width & thickness of a strip of metal (rectangular cross-section), is there a formula into which I can plug these numbers and predict the note produced? Or are there other properties I need to know?

Magnetic Levetation? A Magnet Levitating between two Bismuth plates?

I am trying to make a magnet levitate between two bismuth plates that i made (picture 3,4,5 and 6). As you can see they are round discs about 7mm (millimeters) thick and 110 mm or 11cm (centimeters) in diameter. I bought two magnets; -the one I am trying to make levitate is 30mm (millimeters) in diameter, 10mm thick, and 22kg (kilograms) strong... -the other that is on top, the one that is pulling the magnet up is 30mm in diameter, 15mm thick and 23kg strong I put my two plates of bismuth so that there is about 25mm of space between them... Than I put in the 30mm x 10mm magnet that I want to levitate inside. The other magnet is located above the setup. I very slowly, ever so carefully start to lower the magnet. The magnet between the two bismuth plates starts to shake and at one point hits the top bismuth plate. I can't make it to levitate, either it is on the bottom plate or on the top. I tried to make the space between two bismuth plates smaller and larger, to lower the magnet by a very small amount...it didn't help... PROBLEM: I can't make it levitate, either it is on the bottom bismuth plate or on the top... WHY IS THIS? HOW CAN I FIX IT AND MAKE IT LEVITATE? Thank you for your help! -Stanislav A.K.A. Comodore

But my dream is ( and surely not me alone) to have a wacom cinitq. But its very expensive. To much for me.  I watched the interesting video from roryok,  who find a way with a screen panel via Wii Remote, but it seems very complicated. So i asked me: Is there an easer way for this. So i had an idea about a pen tablet overhead projection with via mini beamer. Take a look to this quickly made scribble : grafiktablett-overhead-projektion/ The most Mini Beamer have an projection space between 15 cm to 1,5 cm . (5.91 to 59.06 inch) . The smallest unit is exatly the widh of an bamboo fun, but is the resolution enough to paint of it in a dark room?  Do you mean that could work and maybe have anybody a minbeamer and an pen tablet for a test?

What is this tool for?

Can anyone tell me what this tool is for?   I came across it all rusted and thought it was some type of pliers or cutter. After I cleaned it up I could tell it was probably neither. What I thought was a plier jaw is actually one piece and does not close and what i thought maybe the cutting blade, actually had lines and numbers, like a ruler. The one small screw that the spring is attached to, will allow you to adjust how far the jaw/cutter will close and the other screw, when loosened a bit allows you to slide the little metal 'arm' in or out, like a measuring template. It has some fancy designs on the handles as you can see and the only marking says "Made in Western Germany".

Drafting table help...

My first Instructable was how to build a drafting table for $50, take a look to get a feel for the design. It does it's job just fine but I'd like to improve upon it. First of all, I don't really have a system to raise/lower the table- I've just been propping it up with boxes and stuff. I'd like to have something attached to the table so that it can easily be adjusted and I'll have a few less pieces to lug around. Second, I need to put a rail on the edge of the drawing surface to keep work and tools from sliding off. I found a small drafting table that I ended up giving to a friend with a rail like the one in the picture below. It's sort of like a metal ruler with L shaped holes in it for screws- so you can lower the rail if you don't want it in your way. Where can I get something like this- or would I be able to make one?

Question about something in the Elegant Universe book I am reading...(KelseyMH?)

Ok, here it goes:   In the description concerning general relativity, the following scenario is depicted:  Jim and Slim are riding a "Tornado" ride (goes by different names, but essentially is a centrifuge that pins you against the outer wall and then drops the floor out from under you. Sometimes calle d PUKE machine). Anyways, looking at the ride from a bird's eye view, one measures the circumference and the radius and we find that the ratio is two times PI or about 6.28.  Now that is from OUR perspective, but from Slim's and Jim's measuring the circumference (so says the book) will give a different answer since they are traveling at high speed (assuming the speed is fast enough to invoke the Lorentz contraction).  Thus, he says in the book that his measurement will come up short and therefore not be the same ratio noted.  I don't doubt this, but I have a problem with not taking into account the lengthing of the circumference because of IT'S motion forward.   Am I missing something?   Why wouldn't the same effect  be proportional to the lengthening of the ruler used to measure the circumference, seeing they are traveling at the same speed?   Am I taking his example TOO FAR (in other words, he is assuming the ride is there but not physical)?   Maybe I over analyze?  :-)

Paper Airplane Contest 6 (Closed)

To coincide with the publishing of my one hundredth instructable, I am hosting a sixth paper airplane contest (PAC6). However, unlike my previous contests, this one is aimed at origami aviators just beginning their flights. Although the previous “PAC5” has yet to conclude, I feel it is an appropriate time to start up another contest, due to the different aims of the two. For this contest, the specification is for a trainer paper airplane. Requirements: 1. Aircraft Requirements: • Ability to fly at least 25 feet (7.62 meters) from a launch height of 5 feet or higher • Durability to fly at least 25 feet, at least 15 times • At least two of the following must be featured on your aircraft: flaps, elevators, rudders, ailerons, spoilers, elevons, decelerons, spoilerons, flaperons, air brakes, slots, and/or slats • Allowed materials include: 2 sheets of 8.5 by 11 inch (A4) paper, 8 inches of Scotch tape, scissors, a stapler, 5 staples, a ruler, a pencil, pen, and 2 paper clips • Aircraft must be named 2. Instructables Requirements: • 1 page (not the intro page) devoted solely to materials required in construction • 1 page explaining how to fly the aircraft • The instructable's license must be: "Attribution Non-commercial Share Alike (by-nc-sa)" • This sentence and link must be displayed on your entry's intro page: “This instructable is an entry in Paper Airplane Contest 6 (https://www.instructables.com/community/Paper-Airplane-Contest-6/)” Prizes: For this contest I will award the publishers of the top 5 performing paper airplanes* one patch each. However, unlike previous contests, each patch will feature its respective aircraft, rather than medals. The first place winner will also receive a 3 month Instructables Pro membership. *Multiple entries are allowed. To keep the distribution of patches wide however, each entrant can only win one prize. How to Enter: To enter this contest, you must send me a private message entitled “My NGT Paper Airplane [Member Name Here]” with your instructable's URL included. (The “NGT” acronym refers to Next Generation Trainer, in order to distinguish it from PAC5 entries). I will then put the link and author's name onto a list on this topic under "Entries". Judging: I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance and suitability, rather than shape, is a more objective approach. The contest begins Friday, June 17, 2011 and ends Friday, July 15, 2011. Entries must be published before Friday, July 15, 2011. From July 16 to July 18, I will be judging all entries.

I hope you found that funny, but more importantly, I hope that you took it seriously.  No, I am not talking about the guy who played Clubber Lang in the third rocky.  I am talking about the K'nex gun that has been built and posted thousands of times, and makes the rest of the Instructables community hate K'nex gun builders.  At this point, pretty much any search done on this site will result in at least one K'nex gun.  What is worse?  They are all the same.  The "T" format is the most simple, most redundant approach to building a K'nex aside from the now heavily discriminated block trigger guns.  They involve three things: 1.  A vertical magazine 2.  A firing ram 3.  A trigger Any gun that requires only these three components to operate is, in my opinion, pointless.  Despite cosmetic features such as stocks and iron sights, all "T" format guns are exactly the same.  Yes, they do work, and some of them even work very well, but at this point, improvement will only occur with change, not with repetition.    Compared to a few years ago, this K'nex community is dwindling on the edge of a cliff.  Many people have lost interest because nothing new was being made, so they just quit.  I do not support this decision, but I cannot blame them either.  Like many of the other "veterans" on this site, I have been on and off, but have never officially quit.  Sometimes one just needs to think.   Hopefully by now, I have made it clear: not another Mr.T should be posted ever again.  They are great guns for those learning the ropes.  That is about it.  There are so many other options out there.  Horizontal magazines, pump systems, lever systems, bolt systems, and so many more.  Make up your own system!  Combine different systems!  There are millions, maybe billions of different ways to put a thousand K'nex together, so why limit yourself.  You are all builders, which means that you see things in your head before you make it.  But sometimes these ideas come to us in inopportune times, so what do you do?  Write it down.  Even if your drawing skills are as pathetic as mine, just scribble it out so you can make sense of it, and then refine it later with a ruler.  Then get to work on it. So, here are the steps you can take to advance this community: 1.  Stop posting Mr.T!!!  He can be a good teacher, but that is about all. 2.  Be different!  My goal when I entered this community was to make guns that nobody has ever made.  No two of my guns are similar, nor are my guns like any others out there.  You have millions of options.  Make use of them! 3.  If you have an idea, write it down!  Even if it seems absurd, I guarantee that it, even if it only be small parts of it, will improve your building skill. I really hope this has made you want to make something different. Not much more I can say.  Just go do it. Oblivitus and TheDunkis have started building a database of different gun elements and different ways of approaching them.  Check it out and feel free to contribute!   http://knexbuilding.wikispaces.com/

Longest Comment on Instructables (Possibly)

Https://www.instructables.com/answers/What-essential-tools-should-I-include-in-my-dorm-r/The longest comment on this site is one by Guardian Fox on the "What survival tools should I keep in my dorm room tool box?" If anyone can find a longer one, please PM me the link.Keep in mind, he typed this with his own fingers, not by holding down the paste command for a day. If that's what you want, then go to https://www.instructables.com/community/the_forum_for_spam/ Source: Guardian FoxFor the dorm room, you only need a few tools. You're not going to be renovating, and you're not going to be doing much woodworking. You aren't allowed to do anything at all to the room beyond hanging pictures (if that), and most dorms forbid power-tools in the rooms no matter what you're use them for. Here's my take on what you'll need for the dorm. I've included a lot of things that seem unnecessary, and you can probably live without some of it... but the kit will get you through nearly any problems you'll encounter at school or in an apartment:-At least one decent multi-bit screwdriver. Look for something with a comfortable grip and sturdy construction. Avoid gimmicks like built in flashlights. I recommend the Piquiq brand which comes in a few different sizes and can be found in many hardware stores in North America. You can usually get their three-piece set for less than $20.-A set of jeweler's screwdrivers. Get a cheap set because these little things WILL get lost. Look for something with at least a few unusual bits as well as the usuals. Get a 30ish-piece set for less than $20. Most handy if you've got a thing for messing with your electronics, but also great for changing a watch battery, fixing glasses, etc.-A basic hammer. Nothing fancy needed here, and I've always preferred an ordinary wooden-handled hammer anyway. Go for a smaller hammer if you only plan on hanging pictures, get a regular-sized hammer if you plan on using it to do real work later on. Stanley is a good brand with decent prices, but there are lots of good budget-priced hammers out there. Drop by a hardware store and pick one that feels good in your hand. Less than $20 for a brand name. $10 or less for a bargain hammer. Make sure the head of the hammer is securely attached to the handle, no matter what brand you pick but a little tiny wiggle is ok. Hang a picture or tap a few finishing nails into a small project. Very handy, even when you use it wrong.-Two utility knives with snap-off blades. One with the small size, and the other with the larger size. There are hundreds of brands of these on the market, and a lot of them are junk so spring for an Olfa (the best i.m.o.) if you can find it. Richard is a decent low-cost brand which is often found in paint stores. Again, avoid gimmicks. The most important thing you need to know is if the locking mechanism works well or not, as a utility knife can become dangerous if the blade is going to slide around while you're using it. Good knives can be around $10-20 each. Cheap, "disposable" knives can be found for less than a dollar, but be sure to buy something that seems sturdy. Add a self-healing cutting mat from the dollar store, and while you're there get a metal ruler for cutting straight lines. Smaller utility knives are good for light-duty applications like trimming photographs or opening packages. Larger utility knives are good for harder work like cutting lots of cardboard-A measuring tape. You probably already have a ruler for school, but a measuring tape is much more useful for around the house. Get a 16' tape for good versatility. Choose one that has a sturdy housing and a tape that slides in and out easily. Bennett is a good budget brand you can find for less than $10 and I recommend theirs over any of the name-brand tapes out there. If you can't find that brand, go to the building supplies store and ask what brand the clerks and outside staff use around the shop. You could skip this one during college, but you'll need it one day and it's the kind of thing you can make uses for.-Pliers. For around the house and crafting I find a pair of long-nose pliers more handy than a pair of linesman's pliers, but both tools have their place. Locking pliers (aka vice grips) are also super-handy. Get one or a set, but avoid the bargain brands. Look to spend at least $7 each for basic pliers, and at least $12 for a good pair of locking pliers. -An adjustable wrench (aka thumb-wrench). Pick a smaller-sized model for your toolbox. Most of the nuts and bolts in the house will be small anyway. Go for something that opens up to 1" or 1 1/2" Brand isn't an issue, but make sure it operates smoothly and won't jam or work loose. Spend less than $10. -Scissors. A usable, general purpose pair of scissors can be found at the dollar stores or in an office supply store. Make sure they open and close smoothly and that the blades don't wiggle. Look for one with a metal screw at the pivot so you can tighten it if it works loose. If you're using it routinely for cutting fabric or any other specific task, spend some extra money and get the right kind for the job or at least a good pair of general purpose ones. Less than $5 for cheap ones, $20+ for quality ones.-Sewing notions; A pack of needles, a roll of white thread, a roll of black thread, and a roll of transparent thread, a few safety pins and any spare buttons you find. That should get you through any wardrobe fixes you may need. Each item in the kit should be a dollar or less, and you can save money by starting with a pre-made kit from a dollar store and adding a few of your own extras. Also highly recommended is this, http://www.dealextreme.com/details.dx/sku.1352 , but keep in mind it is cheap for a reason and needs constant attention.-A soldering iron if it's allowed in your room, and only if you're working with or fixing electronics or jewelry. Get a scrap piece of plywood or something to use as a work surface. $15 for a basic 30w iron. Another $10 for a safer stand.-A toolbox that holds everything. I like the ones that double as a step-stool, which you can find for $20-$30 if you look hard enough (mastercraft and rubbermaid brands). You might like something different, but small plastic toolboxes and even small plain steel ones are all quite cheap so go look and see what you like. You can even use your imagination and just use a plastic tote, a tacklebox, a backpack/messenger bag, shoebox, etc. Just pack your tools in it neatly and avoid putting the heavy or sharp ones on top of the ones that might break.-A plunger. If your dorm room has a bathroom, this is a must even if you never have to use it. It's an insurance policy against one hell of a mess. $10-$15.Anyway, that's all I can think of for tools. Craftier folks need more gear, and less DIY-prone folks need less. Use your best judgment and buy only what you can afford and might actually use. Pick up a few fasteners and adhesives too, usually as needed. Here's what you should probably keep on hand.-A package of assorted picture-hangers and hooks (if hanging pictures is allowed in your dorm). Buy a pack at the dollar store. A few extra finishing nails and small screws would be a good addition to this as well.-Thumbtacks. Buy a pack at the dollar store or office supply store.-Scotch tape, packing tape, duct tape (or Gorilla tape).-Twist ties. Get a bunch from a pack of trash bags.-A package of superglue. Rather than one large tube, get the pack with several tiny tubes so you don't lose your entire supply when one dries up.-Craft wire. Use it wherever you might use a twist tie, but also can be bent into whatever shape you need to become a tool or a piece of art. Dollar stores carry rolls of it often at 2/$1

Your thoughts on "UFO's", strange things and the unknown

Don't take what comes below too serious please ;) I thought for the start of the new year it would be fun to talk about things we take for granted or that we would call nonsense. You know topis like those provided by Erich Däniken and other that think outside the conventional archiological range. Modern science has provided us with new insights into very old stuff but also a new look on things we thought to know better anyway. Here is some food for thought: 1. India... In this beautiful and old country it was discovered that hundreds if not over 2000 years ago people used lathe technology on stones. For example to make pillars with a weight over a few tons... Chains were created from molten rock and in many areas you find polished stone that even after hundreds of years still has a mirror finnish. Some of these creations are claimed to be made with hammer and chisel but how do you get a displayed accuracy that even modern technology struggles to provide? I don't want to clutter everything with video links but check Youtube and you will find temples in India showing musical granite pillars and chambers carved into solid rock with a precision that seems impossible! If that long ago human knd already knew about gear systems and lathe technology, then what else have we lost over time that we now claim as new technologies? How could anyone polish an entire granite hall and a big one that is to a mirror finnish? 2. Peru... Apart from being full of archeological wonders there is also the impossible to be found. The Nazca region shows, in aerial views, kilometer long and perfectly straight lines. In other regions, also in other continents, we can see images of strange people or artwork - again only from high above ground level. Some of the artwork is only in correct proportions and with proper contours if watched from a very specific angle to the mountain in question. The kilometer long lines are not simply on standard mountain faces but instead on top of mountain that have the top removed to be perfectly flat. And even with a lot of posible options to interpret the lines they look like any other huge, modern airport landing strips - including runways and tracks to areas we would call terminals or service bays. You can ignore all possible ways to interpret the design and possible use, what you can't ignore is the missing mountain top and level of accuracy on such a massive scale! 3. Pyramids... On all continents except Australia we find pyramid structures with very similar features in terms of proportions, angles and the way the face in a certain direction. In Egypt they just recently found another hidden chamber... Tunnels, too small for a human to fit point to stars and star signs. Some of the tools used to create were found with the help of small robots but also that some seem to be quite modern in age. Did grave robbers use them at a time were it is beleived that such tools were impossible to create? Or could they be as old as the pyramids itself? In south america we find pyramid structures looking quite similar to those in Egypt - why so similar in features and appearance if there was no contact between the two civilisations? To make things worse some of the Inca structures show tunnel and channel systems "leading" to the pyramid in question. Classic thought is that they were like tunnels to direct water or provide access in the beleive the jungle was not removed to hide the complex. Makes no sense if you see the city like areas that are now exposed and studied. I mean: how would created a city in the jungle without removing the trees?? What could make you wonder is a simulation that was performed several years ago. Based on a computer model in 3D different theories were tested. Irrigation was ruled out quickly, same for access routes or secret tunnels for the priests. One funny student got bored and decided to play god. Assuming the Inca priests would call their gods in the sky temple to provide rain he let a monsoon go down on the pyramid. The result was unexpected so he showed the results to his companions and they did the same test agin but simulated a massive airflow going down directly on the pyramid. Turned out the flow would be directed away under ground with more efficiency than systems Nasa uses today for rockets and space shuttles... Mind you the tunnels are far from straight and without this simulation it was trusted that they could not do this stuff... We now have rocket technology that uses surface direction and vector control. The square and flat designs leave a void insight that pretty much perferctly match the angles of those inca pyramids? Apart from pure coincidence, what could be the reason for this match in shape and angle with a tunnel system perfect to remove hot engine gasses? Ok, I admit, not all continents, the pyramids in Bosnia are just a hoax, so Europe is out of the race ;) Sorry Semir :) 4. Artwork... Be it here in Australia, the African desert or America - we find images of mystical people or rulers that could make you wonder. Again modern tech in the form color filtering, desitity readings and 3D scanning provided us details unseen before. If you think of gods in very ancient times and try to imagine you would be a native: What do think how many different images of their god could 100 people imagine? Let's agree it would be plenty... But if we study artwork in caves and rocks from around the world we find similarities that IMHO can't be explained. Many show features that, compared with modern technology, could be mistaken for helmets, gloves or even manual control systems. Others show things thought to be as simple as pine cones to resemble modern milling or finnishing tools. Again only possible by enhancing details the naked eye won't see. With no contact to each other and often thausand of years apart: What could the reason for having images of their gods show very similar and sometimes identical "features" ? 5. UFO technology and sightings... Some people love to post videos of secret weapons and UFO's that are simple rocket launches at a perfect time and with perfect weather conditions to attract attention. But what about the things we don't get to see? Just recently the US finally admitted to have a program to investigate what we might call "UFO activity", quite costly one too... This means a lot of leaked videos from fighter planes or spy planes you find on the net are actually the real deal. Often "enhanced" with editing tools but authentic ones have been released by the military and other organisations now too. If it happens over US ground and no US organisations admits to be flying the things we see than what it is? Right, it is a UFO - An Unidentified Flying Object! Does not mean it is alien, despite far too many people thinking an UFO must be alien :( UFO means just that! At the time of seeing it the ones seeing it can not identify the craft or "thing". And, no you are not alone! ;) Happens in all parts of the world and even commercial pilots upload what they can't explain. Oh, you are still a sceptic? Does that mean you think some of these sightings must be alien or do think someone down here uses technology we are not supposed to know of? If you are like me you might like to relax watching the live feed from the ISS. In case you are not try it anyway! Every noticed that that despite the stations own speed "forgeign" objects appear to come towards the station or even to grow in size very quickly? If so you also noticed another very strange thing... No matter what happens up there the stream keeps playing, even at times when the station is moved around a bit to avoid a possible hit with debris. But every single time something appears to move around the ISS or come close to it the feed cuts out. Ok, not every time, for well known stuff orbiting around like satellites, other stations, rocket lauchnes or supply flights they stay on. So, what are those flying objects changing course and direction or even circling the station? Why does the live feed cut out once an object is identified to be unidentified? 6. Roswell technology boom... Some think the US did take ownership of an alien craft, you know the stories and movies I mean... So called eye witness reports and some leaked documents all claim certain unknown technology in great detail. Anything from fibre optics and microchips, over "intelligent metals" to light enhancing glass lenses and seemingly indestructable fibres... Some say that if we would had the option to copy and understand the technology to copy it (without knowing anything about it of course) then the tech boom of the 60' would have been instantly. Imagine flat screen TV's and smartphones with GPS 50 years ago for everyone... ;) 7. Great land in the south - Antartica... The mysteries originating from Antartica range from Atlantis over hidden civilisations and living dinosaurs to the often claimed secret Nazi base with submarines and lost technologies. We all know that life as we know it can't really exists down there, so no strange animals, ancient creatures or a possibility to sustain a secret military base some 60 years ago. Or it there more to it?? Warm lakes containing fresh water with signs of life in them have already been discovered. Same for caves under the ice with temperatures far above freezing - constantly and again with signs of life. Ages ago the continent was still joint with other and in a warmer region so no wonder to find fossils. If we already found places that sustained life for thausands of years then what living things might be down there? Maybe even a place like the Galapagos Islands but for life thought be extinct - imagine Jurassic Park for real under the ice ;) With thriving life, vulcanos, rivers, lakes and all long before the dinosaurs it is not hard to imagine the remains under the ice and carved into the mountains. In todays times it all covered by ice and the sea level is much much higher, so again not hard to imagine that there might be rivers running off under the ice and into the ocean. Some maybe even connected to lakes in a hot spot sustaining life. A secret base from some secret part of the Nazi regime over 60 years ago?? Well, with all we know today about Antartica and is also known about the technological options available at that time it is possible. A submarine could have operated for days or even a few weeks under the ice with support ships available. Not just with so called secret tech but simply with a big sub on a minimum crew and the support of crude ways to reclaim and produce oxygen. If an entrance to a river leading to a suistainable area exists or existed at that time it would have been just a matter of time and endurance to find it. Of course we can't know if it was already found and removed or used since those with capable submarines and technology these days would not talk about it ;) But private or non government explorations map and drill more than ever, so once they hit "restricted areas" or create their own base and research station under the ice we will know ;) What to do if you actually see (or think you do) a real UFO?? Grab the oldest and dirtiest camera aou can find, mount it on the end of your longest fishing pole and create the shakiest video possible. And please make no references at all that would allow to get on the loctation, time or date. Jokes aside there is a good option these days, your modern smartphone, telescope, GoPro or favourite drone. A fake is often uploaded in very bad resolution often so low you might think an old webcam was used. Good fakes are often just a rocket launch, so check for this before you claim it is of unknown origins. Modern tech allows us to record a video in 4K at 60 or even 120FPS , so no excuse for a 320x240 AVI video LOL Optical zoom causes bad results so try to avoid it if possible. Image stabilisation can do wonders for free hand shots of moving objects, so crank it to the max even if the resulting video is a bit smaller in resolution. Geotagging is also a good thing as it allows an easy reference. You might see much more with you eye than what the video show, or in the best case the other way around. That means before you upload take a step back and try too see the video like someone who was not there when it happened! Are the movements reall that impossible? Is it really not just a plane, rocket flares? What sounds did you hear at the time or shortly after that might not be audible in the video? Sometimes a plane in the distance still is in the sunlight while you already stand in the dark - keep elevation in mind ;) Compare with other videos online that claim to be taken around the same time and area - sure you did not film a rocket launch? But if your video is crystal clear and shows the impossible in great detail you might want to check for the usual markings on military aircrafts or flashing lights in green and red. Still all good and impossible to explain? Then what are you waiting for? Tell us where, when and with what type of gear and upload the video so we get evidence of unknown technologies in the use/testing or an actual UFO - Unidentified flying object, until we know better. ;) Again don't take me too serious today but enjoy some of the thoughts and let your imagination wander off a bit. Lost technologies and knowlege exists, existed, is found again - whatever you want to call it. If humans could move stone blocks the size of a small house and create them with an accuracy down to the mm then they might have known more than we think they did. If we could melt granite to form new things, manipulate its sound or carve hollow heads of just a few mm in size then again we lost something well worth knowing. If in ancient times people had no way of seeing really distant and dim stars then how were they able to accurately map them and predict their movement? If milling and lathe technology was known and used when in other parts of the world we were happy to create simple and weak tools: How was it possible to create gears and know about planetary gear systems? If the evidence of the work clearly shows advance technologies used then where are the tools used and why can we find any written records or images of it being used? If even the all mighty US military, secret agencies and space programs fail to explain what they encounter quite often since we fly around: What is really that seems to try to hide from us while appearing to watch how we evolve, explore and fight wars? Since you still bother to read all this nonsense: If it appears we have "evidence" of the existance of beings capable of flying or even space travel since the dawn of time and add all the modern evidence: Is it possible someone or something has been watching us since humans came to be? Did "they" guide some cultures at some stage during their evolution to show us modern ways of creating alloys, machine stuff or understand what was magic or the gods at that time? And if they did help our evolution in some parts then why did this greatly improved society disappear with no more trace than their stone remains? How would we react if they dare to help us again? Is there a reason that even after countless encounters noone tried to shoot one of the UFO's down? I mean, not even a claim for trying since Rosswell..... Not any evidence of a recent landing either..... Or are we just watched so closely because they want something back we too from them??? ;) I blame all spelling mistakes on my annoyingly unresponsive keyboard. But if you still find some then feel free to keep them! I still demand a fee if use them to make money from them ;)
