For my, or should I say our next Instructable I want to do a little experiment. The goal is to make a colaborated Instructable with the following rules in place: We each do a single step in the Instructable (excluding the materials step). Materials needed for each single step cost less then € 10 / $ 10. Tools needed for each step should be in most peoples shed (or their neighbours shed), you get the point: no big cnc'ing, lasercutting, wood milling, ... Quality of step description, photo-work, ... should be feature worthy. You get 1 week for each step, allowing for some trial and error, time for personal life, ... If technical constraints require more time, exceptions are possible after clear communication. The concept is to do both the build, and collaborate further on the previous step, back and forth. No communication about the end goal. The project can go in all directions. Iterations continue until we both think that the end point is reached. At that point the Ible will be finished, an introduction and conclusions written and published. I'm open for suggestions on improving the rules of the collaboration experiment, but I'm very keen on trying out this kind of experiment. I am only able to do one experiment at a time in this point in time. So if multiple people are interested, I suggest we make multiple couples and see where we go from there. Who is willing to commit to this kind of experiment across time-zones, boundaries, crafts and expertises? It will be a challenge to get out of your comfort zone, explore new techniques and who knows what else? On spot left to join the experiment, please fill in this registration form. 5 of us already started the discussion on the rules and timing. The general concept is to start November 1th and finish by December 20th, in time for winter holidays.

I am currently doing an experiment to survey human sweat paterns, for purely timewasting reasons, and becuase I am curious of the results. What I would like you to do is put on a fresh pair of socks, then a pair of wellies, and then time (roughly) how long it takes for your ocks to start getting blotches of sweat. Once you have done that, post on this forum: your age, your gender, and your name if you wish, to give you credit. Please help with my little experiment. :)

I came across an experiment in a text on the Philosophy of Science, and I would like to test the results, if I may. Consider this scenario:Linda is is 31 years old, single, outspoken and very bright. She majored in philosophy (it's an American text). As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-war demonstrations. Given this background, which of these statements do you consider to be the most probable? You do not have to justify your statement (though you may if you wish), simply post the letter of the most probable statement: a) Linda is a teacher in a primary school. b) Linda works in a bookshop, and takes Yoga classes. c) Linda is active in the feminist movement d) Linda is a psychiatric social worker. e) Linda is a member of the League of Women Voters f) Linda is a bank clerk g) Linda is an insurance salesperson h) Linda is a bank clerk, and active in the feminist movement. If you are feeling particularly helpful, you could rank the statements in order of probability (most likely to least likely). Thank you in advance. >K< Update: The answers: There isn't a "right" answer. The point is that (h) was consistently given a higher average probability than either (c) or (f). There was no statistical difference between the results of a group of undergrads with no training in statistics, students who had taken basic courses in probability as part of their main subject (eg medicine) or even graduates of Stanford Business School who had taken courses in advanced probability and statistics.

Hi !I tried to reproduce the Double-Slit experiment with a cheap red laser-diode (<1mW).Below are various results obtained from some variations of the experiment ... (with a double slit, with a pinhole, with a thin wire, and with a hair (and also with a single slit who gave almost the same result than with a hair))I also tried to reproduce it with an other source of light (and got electrocuted). But so far, I'm not satisfied by the results I obtained with the light bulb, and I failed with the sun.Do you have some experience to share about this experiment ?Do you have successfully reproduced it with an other source of light than a cheap laser diode ?

Has anyone ever experienced the fourth dimension. Sure this is a topic for science fiction novels, new age conspiracy theories and the new Indiana Jones movie. But dimensions past our own experience are having a big impact in theoretical physics. Flat Land and it's unofficial sequel Flatterland are good books to get a mathematical yet whimsical look into alternative dimensions. The Tesseract from A Wrinkle in Time was a hyper cube as well.So we go from 0D (a point) to 1D (a line) to 2D (planes) to 3D (solid objects) and then what happens when you pull that plane into an unseen dimension?

Has anybody had a real bad experience with a customer? or a customer with an employee? So i was once worked at an ice cream parlor.A woman says to me in Spanish and the only word i recognized was chocolate (there's actually two chocolate flavors, regular and chocolate pecan ) so i gave her the pecan one ...she tastes it and she threw it at me, (lucky for me i had to do the long shift). On that same day another woman showed up and asked for chocolate pecan in broken English and i asked waffle or cone (people never specify waffle or cone) she gave me a dirty look and i gave her the cone,she throws it down on the ground, Being the only one there and I had to mop it up, some customers are yelling at me in spanish (later i figured out it was bad words).

Wow! What an experience. Probably the most enjoyable, action packed, creativity-loaded 2 months of my life. I have been tinkering in what I used to call shops; building, hacking, creating, for as long as I can remember but this... this was more than I had ever dreamed. The residency program at Instructables is a dream come true. Access to a state of the art shop, surrounded by creative, inspiring, fun people. What more could you ask for. Take one of the most creative, forward thinking, cutting edge areas of the United States (the Bay); the coolest city in that area (San Francisco); the prettiest/most unique part of that city (the Embarcadero) and slap the worlds best creative work shop on it, right over the water (Pier 9). Walking in the doors for the first time was surreal. From the swinging meeting table to the coolest kitchen I have ever seen; water jet to brand new Bridgeport; 3-D printers to industrial sewing machines, Instructables has done it. Within hours of being assigned a desk I was signing up for workshop classes and using Autodesk software to mock up some design ideas for the bicycle frame jig I spent most of my residency building. I later used this jig to build a bicycle frame. Not only was I having a blast building what I wanted to build, I was building skills I hope to use professionally. I am hoping to start my own business building custom bicycle frames. The time to tinker and build at Instructables gave me a tremendous jump start. I wish it hadn't ended.

Well I've been conducting a secret social experiment using shopping bags and the environmental topics everywhere as a media for this to happen. Basically my plan was to see if I could affect the decision of whether or not to take a bag when it's not completely necessary, to change the course of decision I used different phrases and tried to get a more accurate measure by choosing the same people that come in for milk or bread each day.The phrases are:'Would you like a bag?''Do you want a bag''Do you need a bag?''Wee bag there, mate?'Bag?'The results were really quite interesting, the one putting emphasis on need (very subtlety) reduced bag takings by over half in a day, whereas 'Wee bag there, mate?' produced a very high bag taking day because it detracts from the bags impact as an object. The other things I found was that it's actually possible to control some customers bag taking completely, there's a customer that comes in every day to get milk and I have managed to control his bag taking with about a 95% success rate, so shopkeepers unite and we can eradicate unnecessary bag taking, thereby reducing the majority of plastic bags that end up in the street and ocean, landfills are another story, thankfully my stores bags are fully biodegradable...What do you make of all this, and is it possibly a bit much power to give to a shop worker...On another note I have curtailed the efforts of one customer I know as the bag thief, he used to take five or six for various uses, through gentle shame jibing he's now down to one.

I'm currently experimenting with piezoelectricity.And at the moment my experiment is limited to just a few piezo sparkers extracted from cigarette lighters.The sparker works with observable voltage spike on my multimeter. No voltage spike however when I use the tiny crystal (the size of a zippo flint) taken out from the sparker.I was trying to replicate this experiment (without the oscilloscope):Piezoelectric Rochelle SaltAnother thing, Would continuous vibration produce continuous voltage?It is known that piezo crystals produce high voltage, yet very low current. What are the options to increase the current? Would winding un-insulated copper wire around it (or any kind of contact with conductive metal) increase the current? Apart from lighter, what other surplus sources of piezoelectric crystals (i.e. quartz, PZT, Rochelle)? Can the crystal in RC toys, radios be used to generate electricity? Although there is the option to grow my own Rochelle salt, I'm not looking into it at the moment since it's going to take quite a while to grow.Thanks in advance!

As the economy ebbs and flows, so does the advertising industry. Since Instructables' only current sources of revenue are contextual and brand advertising, our future has a few more question marks than it did a few months ago. We're currently engaged in a number of experiments to see how some of our ideas around alternative revenue sources pan out. For example, we're currently asking non-logged in users to create an account to access all of the large images in an Instructable. Whether we decide to make any of these changes permanent depends on how they perform, feedback from the community, and if and when brand advertising picks back up. Advertising underwrites the creation, hosting, and distribution of a tremendous amount of awesome content. Keeping that content flowing when advertising has a down turn requires some creative thinking, and often requires business models that are not free. While we have no plans to charge our community to submit or get access to the Instructables content (because really, it's your content in the first place), we are experimenting and thinking about premium models around how that content is displayed and other features you may find valuable. If you see something out of the ordinary, please give us the benefit of the doubt while we experiment to find ways to ensure we're around for a long time to come.

(I slightly changed the instructable into a forum topic and an instructable)The Instructable Half"Global Warming" Experiment #1:As you can tell by my quotes around "Global Warming", I personally don't believe that this theory is happening. Theres facts I can use to prove this. However, even I believe that no matter how you put it, there's going to be some bias. Also facts are boring :PSo, what I have planned, is to do a series of experiments on what global warming might cause if it were real.I'm doing this because I've heard people claim some extraordinary things, which based on data won't happen.I could post an instructable with a bunch of facts, and I might. But for now, I want to set up a couple collaborative experiments. One reason I want collaboration is I'm biased. The other, is so you can't complain about my methods.I haven't done the experiment yet, I really don't know if this will help, or hurt, my case.The experiment is to determine if "global warming" could melt glaciers, thus cooling the ocean. Notice here I'm assuming global warming is happening. It isn't. But when people make claims on the news and stuff, they are assuming that too.Please comment if you would like to change my methodology, OR you want to do the experiment.I'm going to describe how the Instructable (and hopefully the rest in the series) will work.1) I, or anyone, proposes a framework for an experiments and writes up an Instructable. (Will be referred to as "I" in the following steps)2) I monitor the suggestions, editing and fixing as needed. After about a week or so, I go onto step 3.3) I preform the experiment to the best of my ability, and write up an additional 2 steps.3a) The first outlines my changes. This could mean I didn't have a 4x8 loaf pan, and I had to use a 3x8. Or it was plastic. Whatever. These small details are important3b) The second outlines the data and conclusion. This may have images of the experiment, graphs, tables, sensor data, Whatever. I also make a note of my previous bias.4) Wait for more people to run through the experiment, adding them as collaborators.5) Write up a conclusion to everything, OR do some more investigating.Its not that bad, however the whole process might take a few weeks. (I don't know)Scientific MethodThere are seven steps to the Scientific Method, which we will follow:1. Define the question2. Gather information and resources3. Form hypothesis4. Perform experiment and collect data5. Analyze data6. Interpret data and draw conclusions that serve as a starting point for new hypotheses7. Publish results(Thanks Wikipedia!)#1 was done in the introduction.#2 I've already done, however you only have to look into data you'll need during the procedure.#3 I've done it, but I'm not telling you (I don't want a bias, even though I've hinted towards my guess)#4 - We're going to expand this out. More later!#5 and #6 sort of come together in this format, will be done as we go along.#7 is done as we go!Okay, #4. Remember back to High School, remember Lab Reports? Well basically there will be a step for each segments (leaving some out). We sort of do this already in most instructables "What will happen", "What you need", "How you do it"; this time more formally. Due to Lab Reports being unstandardized, I'm breaking it down into:IntroductionMaterialsProcedureDataIts shorter than your average one, due to the fact in Data, you have hypothesis and stuff I don't want to reveal yet ;-)The following is the framework, you can also see my instructable:(This is a framework, remember. Its not supposed to be "done" and perfect)Materials*Large basin of some sorts.*Water*Ice*Lamp + Light bulbs (100W & 40W)*ThermometerProcedure1) Fill large basin/pan with water.2) Take and record standing temperature of water.3) Add ice off to one side of the pan.4) Take temp. of water every five minutes until it starts to level out, at least 4 readings.5) Replace water, and repeat steps 2&36) Shine lamp w/ 40W bulb off to the non-ice side of the pan, but allowing some light & warmth to reach the ice. (Roughly 20-35%)7) Repeat steps 4&58) Repeat step 6 with a 100W bulbTake pictures throughout!What now?Okay, I'll be updating this with your comments over the next week or so. If somethings wrong with it, POINT IT OUT!!! I'm going to add my thoughts in as well. (I still feel its missing some things, I can't put my fingers on them, though!)

Not sure just how accurate it is in the 250 to 500F range. This device seems to read 5 degrees high at the 100F range. ** ironically, the temp is higher on the "low" setting. When the fan is moving less air, that air is hotter. One of the tricks, I imagine, might be to fully melt the plastic without burning it. Suggestions welcome. Further results will follow.

Being an Artist in Residence at Instructables was an amazing experience. It's difficult to put into words but I'll give it my best shot. Let's start at the beginning! Because where else would you start? I'm a college student, but I wasn't when I started to love building things. A knee injury years ago took me out of wrestling for a summer and I used my ample free time during that time period quickly filled up as I was excited by the idea of breaking water into hydrogen and oxygen. Over the past five years, I've grown to love making all sorts of things. Instructables has always been a fantastic community to get ideas for projects and share what I've made. After being part of the community for so long I wanted a chance to be a bigger part of Instructables and have the opportunity to meet some of the people who I've been following on this website for years! Hopefully that only sounds mildly creepy. The Artist in Residence program allowed me to have just that opportunity. I had the honor of being one of the very first Artists to make use of Instructables/Autodesk's brand new facility. It's incredible. If you're on a tour, it will be referred to as the greatest workshop and creative space in the world, and after working in it for a month, that's an easy statement for me to believe. The metal shop is where I loved spending most of my time as I worked on my main project: a jet engine. However, I barely scratched the surface of what's possible even when I dabbled in playing around with 3D printing and laser cutting. I'll post links to the projects I did when I'm done at the bottom of this post! I could go on and on about how exciting it was to learn how to TIG weld, or pull my first 3D printed object out of the printer for cleaning. That's not what I loved most about being an Artist in Residence. Don't get me wrong, that's why I was there, and I loved every minute of it! But what I loved most was just being in the office at Instructables. It was an amazing feeling to get to interact with lots of different people who all in some way loved to make things. Being around people who know what Maker Faire is meant a lot to me! Usually mentioning it only yields confused faces in my city. It was great getting to talk about different projects people had done or were working on, which made me love "Build Day"s more than anything. Being at the headquarters of Maker Culture made me feel at home. I've been away from the Pier where Instructables HQ is for a few weeks now. I miss everyone I got to meet there, and I miss having the resources to make anything I could imagine. Being and Artist in Residence will always be one of my best memories ever, and I can only hope that at some point I'll end up back at Instructables to see the awesome people I met and build some more cool stuff. Thank you to everyone at Instructables who made my short stay a great experience! I can't thank you enough. - Projects! https://www.instructables.com/id/How-to-Make-a-Mini-Compressed-Air-Turbine/ https://www.instructables.com/id/3D-Printed-Modular-Ball-and-Socket-Joints/ https://www.instructables.com/id/Make-your-own-Instructables-Robot-Keychain Jet Engine Instructable coming later!

Some people just love to play with magnets and have a lot of them.If you are just like that and like to tinker a bit then I might have something for you.What magnets you use for the following experiment does not really matter but you should have 20 or 30 of identical properties.Can be disk magnets, block magnets or cubes, just not spheres ;)If you have a 3D printer you use it to make it fancy but a peice of wood, acrylic or such and a drill will do for round magnets.For cubes or flat packs you can make retaining walls on a flat surface.The experiment goes like this:I assume you already tried ways to combine your magnets to make them stronger, like stacking them up.But there is another way to really increase how strong they are combined.Start with one magnet at the center.Then like a ring add more magnets around it but with the oppisite side up.The created mounting solution is to prevent them flipping up and together, you want them as close as possible though.Add another ring and change the direction of the field again.Try this magnet, once all magnets are secured and compare the holding strenght to any other combo you tried so far.It will be much higher for the same amount of magnets.If you want to prevent the use of glue then try to create your mounting system with a really flat but strong enough bottom - this will then be the contact surface.Slightly reduced strength but you can re-use magnet with ease.But if you want to get a really strong one you need cube magnets.Like before you want to create some sort of grid, this time we go for a square.Start with cube in the center, facing north up.Leave enough space in your construction to add 8 more cubes around it - like on the face of a rubik's cube.Leave them empty for now !Add nother row, this time 16 to keep the square.Of course these one go with the south side facing up!Again one empty of 48 and then one last one with north side up with 196 magnets.Ok, to be fair, you wouldn't be able to pull it off a metal surface unless you used really tiny cubes, so if in doubt then go for just to 48 and leave the enter one out for now.Should be quite intense but similar to what any other shaped magnet would have done.Time to fill the voids!Add the cubes in the spce between the magnets so the north and south side face the magnets next to it!So basically sideways but in the correct orientation.You can then also add the center piece - try either orientation for that one ;)What happened now is that you forced the magnetic field lines to go up instead od for trying to go the easiest and shortest way to the next magnet.And "up" is where our magnetic surface would be, which provides the now overdue shortcut for the magnetic fields.Be amased how much stronger this version is and how much even 3x3x3 cubes would accomplish.With 10x10x10mm N52 magnets you might be able to use them support our wieght if you pull straight dwon from a horizontal surface...Ok, kidding, not just might, unless you are really big...One 10x10x10 might hold about 6kg.Stacked up a bit more but having 20 or stcked up would not be much stronger than 10.Even just 25 magnets with one in the center, one row of sideways orientated and one row with opposing field to the center one would be hard to remove from a steel surface.If we go with the imagined 6kg per magnet we could assume to get 25 x 6 = 150kg of holding power.Check you single magnet first then compare to the square of 25 ;)Consider using some plastic between magnet and surface so you can at least slide or pry it off if you have to.You can also combine magnets or a new one that has one side appear much stronger than the other.Meaning that for example on the north side it could hold 20kg while on the south side only 5.

Greetings, My experiment, I heard that taco bell makes their re-fried beans out of a bag of dry mix. Im am not sure how true this is but wanted to see if I can make my own mix. My first experiment is to see what happens if one grinds up dried beans and try to cook them. The problem is I don't know of anything that can grind up a dried bean. I did find some grain grinders but I don't know if they are up for the task and the cheaper ones seem to break easily based on the reviews. I suppose I could bash them between a couple of rocks, but experience has taught me that the part I want to keep will most likely go flying. Any ideas will be appreciated

When I say relatively safe I mean something that doesn't emit poisonous gasses or toxic waste. Thanks for any help. Update: I'm not worried about the safety of vinegar and baking soda, I added a safety request because I was almost very stupid mixing chemicals without checking about results. I almost created a gas used to exterminate people. There is no need to lecture me on how stupid this was, I already know.

After my experiment which turned out to be lead oxide, I did something else. I bought a lump of Calcite, and found out it dissolves in acid. Therefore, I couldn't resist breaking off some lumps and putting those in vinegar. For at least a week, there was no significant change in the container, but after another week, all of the vinegar was gone, and no sign of the calcite lumps either. only a white and a pink residue. What I want to know is, is this Calcium? Or something else?

Otherwise, if i cant microwave as usual without the door, if i was to remove half of the mesh in the microwave door (like every second row ect, not one half side) would that have any negative implications? and then, what would be a safe videoing distance from which to video the microwave? i want to make this as visible as possible, while keeping maximum power, also while not wrecking my video camera.
Question by oldmanbeefjerky
Ok, I was tinkering around with some interesting materials today and I invented a strange thing. It's a chunk of greenish resin (impregnated with certain chemicals) about the size of a soda bottle cap. I was shaping it with an electric sander (it had sharp edges), and I noticed it gave off dim green light wherever it was touching the sander. I decide that the friction/heat generated by the sander somehow made it give off light... So I went to a dark room and dropped it in a beaker filled with water I boiled in the microwave. AND IT LIGHTS UP It gives off a pretty bright green light. Not bright enough to read by (unless it's big text), but easily bright enough to navigate a cluttered room. I dunked it in cold water...and the light practically turns off. It seems to get brighter the hotter it gets. I hit it with my torch, and it lit up REAL bright, and then "turned off" (that particular sample doesn't work now :S) What should I do with it? Anyone have ideas for possible applications?

Instructables' Artist-in-Residence Mario Caicedo-Langer is pretty hands-on. He can make a robot out of anything, but was intrigued by the 123D suite of apps. I asked him to document his experience here... http://blog.123dapp.com/2013/04/transformational-experience-for-instructables-artist-in-residence It's pretty cool - the next step is printing the robot in one print, while still having moveable joints.

You can also use this forum for tips on competing, or you can share your ideas on how to compete better. Those of you who compete in these sports will have their name displayed here, and stats about them, such as their fastest times etc. Remember! I want this forum to be as "clean" and appropriate as possible, so don't be calling anyone a loser just because they can not run as fast as you, or jump as far as you, or anything! Just to start this forum off, I will be the first one to post my experiences on this! You may share anything you wish! some of my goals include competing national, and then moving on to international, beating the world record for high jump, and beating bolt at 100 meter! Have fun! knexsniper1: - 1 mile run: 5:27 - 100 meter: 10.62 Kiteman: -did an eight minute mile cross-country.
