I work at a BSA summer camp each year teaching archery and a little class about things not to bother while at camp. I have to find these bugs/spiders each year and catch them at some risk. I would like to have a perm. display for them to look at with out having to worry about me or them getting bit. I have did a search for said bugs on line but found nothing. Does anyone know how to use the liquid plastic to encase bugs? Please email me at email@example.com. Thanks.

No real point to this but I wanted to post anyways because it is kinda cool. Went to the doctors office with my wife today because she had this spot on her ear that was bothering her. Well the doctor wanted to freeze it with liquid nitrogen to get rid of it. Well of course my ears perked right up because to be honest this was going to be the same time I was even in the same room as this *cool* stuff. I asked her to pack some up for me to take home. She laughed and said she wished she could but did not have anything to transport it with. But she brought in a styrofoam cup about half full of it. She used a quetip to apply it to the spot on the ear three times. Then handed me the cup and said "I know the geek inside you wants to play with it.". Our doctor knows us well. But the bummer part was that I did not have anything to put in it. So since the only thing I had to freeze was myself I put the quetip on my finger. ......Yes this hurt. But it was still fun. Then I was left to just watch it boil and then blow on it once in a while. But when we were leaving I handed the cup back to her since I figured I could not leave with it and it was almost gone anyways. Then she said something she liked to do with it was to pour it on the floor. I was pretty cool to watch the "fog" it kicked up and listen to the floor crackle. Anyways, that is my story of the day. I did not get to do much with it, but it was still *cool*.

Its so hot and... well.... I made a device to cool myself down! I might make an instructable, but basically, I took two 20oz bottles with caps, poked 2 holes in the top of one, 1 hole in the other. I then ran tubing between the two, and in the bottle with 2 holes, I added a bit of tubing to put the air intake below water level. I filled the 2'holer up with icewater, and blew a bit on the air intake to get it started. It works very well, to say the least! :P

Back when I was a kid I had a little chimistry set and part of it were instructions on how to create your own chmical garden in a jar.The metal salts only "grow" in the areas with lots of water while being cured into somthing more solid when it contacts the waterglass.Quite nice trick for kids of all ages.Another and commercail use is as a binder for refractory uses.On a home level you can just crush up some vermiculite and perlite to create solid and light weight fire bricks or plate - with just waterglass as the binder.Although for this purpose you want a higher amount of cat litter in your mix.Cat litter???Yes, cat litter is the same as silica beads but it dissolves much easier in the reaction with sodium hydroxide, or drain cleaner.60g of crystal cat litter, 80g of sodium hydroxide, 100ml of water.Mix it carefully and without getting too much sodium hydroxide in the mix to quickly and you have a jar of watergalls - easy...But there is other uses too, like you could see in my Ible about making your own ferrite.In some areas it is still used as a flame retardant or to fireproof materials that otherwise would combust too quickly.Wood that was vacuum treated with waterglass and fully dried turns into a rock like substance that looks beautiful once polished.And it has a really hard time burning...As it cures like glass with just little heat it was used in Fukushima by injecting it into the soil to form a barrier for the radioactive water.The heat from the radiactive water helped curing the mix...You can even use it to repair your cracked potter and glassware..Holes or leaks in your exhaust system? What a pain if you are too short on money to replace the parts.So a lot of us pay quite a bit of money for repair putties and bandages to seal the lak at least for long enough to consider a real fix.Did you know that all these putties and such are nothing but waterglass, glass fibres and filler material?The later often just very fine sand.Easy to make you own in bucket loads for less than what the repair kit costs LOLA total pain in the behind is if your old car gets a water leak.Usually it is a seal on the pump, a hole in the radiator or a tiny crack.One to to fix it for a while is to add an egg white to your cold radiator water or coolant.Then go for a drive and the egg white will boil off and dry where it comes into contact with air - outside you problem.Works remarkably well and won't harm any part of your engine either.Only downside is that it usually only lasts for a few days, being a natural product and such.Some people though claim they got weeks or even months out of such a cheap fix.A btter and more permanent way to seal such tiny leaks is to use waterglass mixed into the cooling system.It will form a lasting glass like seal that has no issiues under high heat or pressure.It even fixes your leaking head gasket if the water goes not get into the oil jet.Oil getting into the water might still still be fixable with waterglass.Water in the oil means the waterglass could enter the oil and if that happens you end with glass in your moving engine bits.A sure way to kill every engine and used to properly destroy them for recyling purposes by law in some countries.Waterglass is added to the engine oil and then it runs until hot enough for the water to evaporate.At this point the engine and all bearings just permantly seize.Waterglass added to cement provides a good barrier for oil and other liquids, making a spill cleanup much easier as the spill can't really penetrate the concrete.My personal favourite though is to use it for the easy removal of unwanted paint gretings on walls and such.You know how some kids think that a spray can with paint and a clean wall make artwork...If said wall is "painted" with a a mix of waterglass and sugar the spray paint will stick as good as before.But then you come with a pressure washer and clean it off in a few minutes and without any traces left on the wall.Sadly you need to re-apply the protective coating before the kid with the spray can comes back next night...What are your uses for liquid glass?

I am building a biodiesel production system. at different points in the process, a tank will have different liquids in it (sometimes more than 1 type, separated out). for instance, there is a point where glycerol sinks to the bottom, while biodiesel floats on top. what i want to do is drain the glycerol from the bottom of the tank (via electronically controlled solenoid valve), then when a sensor detects a change in material (biodiesel), shuts off that valve and opens another (final product tank). for the life of me, i cannot find a sensor that will do this for less than $100. preferably, i'd like to spend less than $30. i can work with a resistive type or voltage type sensor. i just need to be able to make that distinction of material change... any ideas?

I am looking for an alternative to the alcohol dispenser I saw on your site.I am looking to make a dispenser that can handle being used all day long filling 2 oz bottles with a fine light oil. Your alcohol dispenser is close but seemed rather light weight. I would also prefer to use some sort of inexpensive timer rather than the proximity sensor used in your presentation.I am wondering if you could furnish me with a list of materials, where to get them, and a wiring diagram. This filler will be used to help support a mission project for an orphanage of children that lost parents to HIV AIDS.As an architect, I was able to design and donate blueprints and supervision for a children's home and chapel at this mission but a little device to fill these bottles has me stumped. I am now 83 years old and don't have access any more to all of the engineering help that I once had, nor do I have the finances anymore to purchase the high-end units that are available.

Http://articles.latimes.com/2009/feb/23/business/fi-magicwater23I think someone with more time than me should see how to do this most efficiently and see if it work!The article:Sounds like the old "Saturday Night Live" gag for Shimmer, the faux floor polish plugged by Gilda Radner. But the elixir is real. It has been approved by U.S regulators. And it's starting to replace the toxic chemicals Americans use at home and on the job.The stuff is a simple mixture of table salt and tap water whose ions have been scrambled with an electric current. Researchers have dubbed it electrolyzed water -- hardly as catchy as Mr. Clean. But at the Sheraton Delfina in Santa Monica, some hotel workers are calling it el liquido milagroso -- the miracle liquid.That's as good a name as any for a substance that scientists say is powerful enough to kill anthrax spores without harming people or the environment.Used as a sanitizer for decades in Russia and Japan, it's slowly winning acceptance in the United States. A New York poultry processor uses it to kill salmonella on chicken carcasses. Minnesota grocery clerks spray sticky conveyors in the checkout lanes. Michigan jailers mop with electrolyzed water to keep potentially lethal cleaners out of the hands of inmates.In Santa Monica, the once-skeptical Sheraton housekeeping staff has ditched skin-chapping bleach and pungent ammonia for spray bottles filled with electrolyzed water to clean toilets and sinks."I didn't believe in it at first because it didn't have foam or any scent," said housekeeper Flor Corona. "But I can tell you it works. My rooms are clean."Management likes it too. The mixture costs less than a penny a gallon. It cuts down on employee injuries from chemicals. It reduces shipping costs and waste because hotel staffers prepare the elixir on site. And it's helping the Sheraton Delfina tout its environmental credentials to guests.The hotel's kitchen staff recently began disinfecting produce with electrolyzed water. They say the lettuce lasts longer. They're hoping to replace detergent in the dishwasher. Management figures the payback time for the $10,000 electrolysis machine will be less than a year."It's green. It saves money. And it's the right thing to do," said Glenn Epstein, executive assistant at the Sheraton Delfina. "It's almost like fantasy."

Hi everybody! How are we all? I'm working on my latest project sending a weather balloon to around 100,000 feet and capturing the journey on camera. I've done it before as you may see on my blog www.joshingtalk.com. Anyway, my newest project involves making art at around 100,000 feet and this is where you could help! I know this could be done fairly easily but I do not have the knowledge to do it. I need a container that dispenses a small solution of liquid every 15 minutes. Now I've done a lot of research and this is the best I can come up with: http://www.amazon.co.uk/Fishmate-Automatic-Aquarium-Fish-Feeder/dp/B000YK5W18 It's gravity action, many compartments, on a rotary basis, at timed intervals BUT it will only allow for a few rotations over several hours. I'm looking for 8 rotations over 2 hours. I also checked out water timers but they seem a bit more complex. Maybe you have an alternative idea? Maybe it's 5 minutes of fiddling for you? It feels like to the right person, this should be fairly easy to overcome. I'm based in the UK and if you would like to help me with this project, I'd love it and be really appreciative! It's all good fun and you could see your device hovering at 100,000 feet.... Many thanks, Josh Update- Another vital thing I forgot to add is that this device needs to weigh under 200 grams.

Here's an idea for the science fair: Bouncing liquids. Explain how it works and do something cool with it!http://www.nature.com/news/2007/070716/full/070716-17.htmlLiquids bounce againJumping jets move from the bathroom to the kitchen.After bouncing shampoo, physicists now bring you bouncing cooking oil. A team in Texas has found that the trampolining of a liquid jet falling onto a bath of the same liquid is more common than expected.Last year, a group in the Netherlands studied this bouncing effect for a jet of shampoo (see 'Puzzle of leaping liquid solved'). The bounce, which was first reported more than 40 years ago, happens because of the peculiar nature of shampoo, which gets thinner (less viscous) as it flows. A jet of it hitting a liquid surface is therefore lubricated by a thin layer at the interface, enabling it to bounce off rather than merge.But the liquids now studied by Matthew Thrasher and his colleagues at the University of Texas in Austin don't have this property. The silicone oils in their experiment are viscous but have 'normal' flow behaviour, like water.The researchers directed a jet of oil vertically onto the surface of a tank of the same oil. They found that the jet could undergo both a 'leaping' rebound and a bizarre 'flat' bounce in which it sprang horizontally across the liquid surface.The bounce here is due to a thin layer of air that separates the two liquid surfaces, the researchers say in an article submitted to Physical Review E.They point out that the effect can easily be recreated in a kitchen experiment with cooking oil. Just fill a glass pie dish with about 4 centimetres of oil and pour onto it a thin stream from a cup about 3 to 6 centimetres above the surface. While pouring, move the stream in a circle about once every 2 seconds (or perhaps less messily rotate the dish on a Lazy Susan). The bounce can be encouraged by passing a chopstick or some other small rod through the stream every now and then.

Well me and my friend added KNO3 and sugar to a tin coffee mix container to see the reaction. So it all went well (smoke shot all around and stuff the can turned red hot. ) but when I got to the can after I noticed it was still smoking a little I noticed that there was a tan-ish colored fluid at the bottom of the can that seemed to be the source of the smoke. Out of curiosity I dropped the dead match And I was surprised to see that it had lit on fire and completely disintegrated in less than 5 seconds. Anything I put in it (Paper cup plastic bottle) was burned and dissolved. It wasn't until I poured cold water in(after which boiled instantly) was i able to dump the liquid into the ground. So my question is what was that stuff?

Hello. I have little experience with these things so I am seeking help here. I have a prototype design for a liquid drop monitor. There is a tube that drip liquid and be detected by a photodiode hooked up to an Arduino. My question is about how to build an enclosure for it subject to my requirements. If anyone has advice for any of my needs below, the help would be much appreciated. I am not very knowledgeable of these kind of things. The circuit is in in two parts on two small breadboards, the detector on one side and an LED on the other. A tube will go through the box vertically from top to bottom. The box will be made out of acrylic because it's cheap, see-through, and I have access to a laser cutter. First question, how can I mount these breadboards in the acrylic box in such a way that I can remove them when needed or later replace them with a PCB later. Second, what sort of mechanical device can I use to adjust the distance between the LED and the detector? Essentially, I just need to be able to move the LED towards and away from the detector in one dimension. Third, I will need to change out the tube often to adjust the thickness. How could I allow for adjustable sizes? If the tube hole is the same size then I will only be able to fit one. Alternately, I could move the detector and LED horizontally to select different tubes. Is there a mechanical device for this? Fourth, I'm using acrylic because it's cheap and I have access to a laser cutter, but most designs for boxes I've seen are not made to be opened. I will need to be removing and rewiring things often. So is there a common or easy way of making/mounting a hinged acrylic door or a removable top? I apologize for the simplicity of my questions, but I really could use the help. Thanks!

I have a cylindrical container(around .75 liters) that is filled with water. I want to accurately pour a certain amount of water in a cup. How can that be done?? My idea (might be complete fail) : I put a hole at the bottom of the cylinder, and a door mechanism that opens and closes the hole. The door will be controlled by timing. So lets say i want to pour 50ml of water in a cup. Using some physics i can get the time needed for the water to freefall into the cup and i will open and close the door accordingly. The idea sounds a bit cheesy so I wanted some opinions. Picture is attached. Some comments I would appreciate: 1. Is my door opening and closing mechanism a complete fail? A small motor will turn the pinion which will in turn move the rack horizontally opening and closing the door. Note that I want the door open/close mechanism to be as small as possible. 2.If the drink is not water, lets say orange juice or red bull, will the timing vary considerably? 3. Any ideas how to accomplish this in another way other than timing and opening closing a door? I want minimum complexity, and the amount poured doesn't have to be very exact, lets say within a 10% margin. (This is basically my question in the first 2 lines). Note: At my disposal i have simple machining methods(lathe, milling, drilling, cutting), but nothing too fancy. I have sufficient knowledge of microcontrollers and electronics. Thanks in advance!!
