I have close to 100 (I found a box of them, Some are lost throughout my house) tiny vials and I need an idea what to do with them. If the idea is good I'll make an instructable and include you name. The lids do have holes, but it comes with a little sheet of plastic or something if you want to seal it, a couple of pics.

TRITIUM! So I get a lot of questions from my post and instructables. Tritium Vials are Radioactive Hydrogen H3, also known as hydrogen-3 is a radioactive isotope of hydrogen. It is contained in small glass vials coated in colored phosphor then encased in glass or sealed plastics. These are commonly seen in Gun Sights, Watches (TRASERS) and some Emergency Exit Signs. http://en.wikipedia.org/wiki/Tritium_illumination Small amounts are legal and for approved uses. Read the NRC guides Typically the Trit vials are small, expensive and dim. The latest GID (Glow in the Dark) Chemsticks, LED's and GID Powders or paints seems much more effective and usable. * Cyalume, as used in a lightsticks, emits light by chemiluminescence of a fluorescent dye (also called fluorescor) activated by cyalume reacting with hydrogen peroxide in the presence of a catalyst, such as sodium salicylate. It is the most efficient chemiluminescent reaction known. up to 15% quantum efficiency. http://en.wikipedia.org/wiki/Chemiluminescence New LED low power requirements and high Lumen or light output have provided many solutions that are low cost, high power and longer lasting. GID Paint or Powders are "charged" with light or daylight sources as with your traditional kids toys or stickers. New products are brighter, glow longer and are now waterproof, have many colors and applications. http://www.4physics.com/catalog/GIDinfo.php Also this is occasionally confused with the chemical illumination. However these paints powders and materials use common phosphorescent materials include zinc sulfide and strontium aluminate. Use of zinc sulfide for safety related products dates back to the 1930s. However, the development of strontium oxide aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to the novelty category. Strontium oxide aluminate based pigments are now used in exit signs, pathway marking, and other safety related signage. http://en.wikipedia.org/wiki/Phosphorescence Hope this helps! 01/2011 - Update Source for Materials http://www.darkniteglow.com/glow-shop/ ERCK www.Candlepowerforums.com Additional Tritium Resources * U.S. NRC: http://www.nrc.gov/reactors/operating/ops-experience/grndwtr-contam-tritium.html * U.S. EPA: http://www.epa.gov/radiation/radionuclides/tritium.htm * U.S. DOE (Argonne National Lab): http://www.ead.anl.gov/pub/doc/tritium.pdf * California EPA: http://www.oehha.ca.gov/water/phg/allphgs.html * University of Idaho: http://www.physics.isu.edu/radinf/tritium.htm

I was sitting on my couch today, thinking about ideas for birthday presents when I had the idea of making tritium earrings. However, I'm not sure where I should obtain the tritium vials, and what size I should get. I'm looking to keep a low budget, $25 maximum.

I needed to use some Marine-TEX epoxy for a project I'm currently working on, and found that I've misplaced the little vial of hardener. Are there any other hardeners I can use for this epoxy? I've quite the collection of various epoxies and hardeners, but I'm not sure if any other hardener will work with the Marine-TEX epoxy resin. Help anyone?

Hey guys, Over the years I've collected a fair amount of glassware other junk from various institutions. Unfortunately, my preoccupations as such don't permit as much time to pursue my hobbies. However, I'm abroad now, and will be until mid-December, so I can't actually supply much more info than generalizations about the materials. If anyone's interested in hearing more, reply on this thread or message me. Also unsure about some of the fitting sizes. To my knowledge I'm pretty sure I have: 1 - Allihn Condensor 2 - 1L Round bottom boiling flasks sv. - 500ml Round bottom boiling flasks 4 - VariACs 2/3 - Cases of 15ml glass screw-top vials 2/3 - Cases of 15ml plastic screw-top vials many - Ground glass stoppers many - Ground glass neck bottles (apothecary style!) 3 - Glass retorts 1 - 5L Glass carboy with broken outlet nozzle 1 - Drying chamber with vacuum attachment 100's - 15/30 ml glass tubes They'll be shipped from New England; only domestic inquiries please.

Okay so I'm trying to build something that will allow the li I placed on a vial to open and close according to the time protocol I assign it on Audrino. The lid is a flip, spring action lid made from hard plastic. The programming shouldn't be a problem, but I wanted to see if there is another easier way to go about this keeping the whole thing under 100grams. At first I was thinking adding Velcro to the top on the lid and on the side of the vial that the lid retracts to. The lid moved by a micro piston of some sort all powered by a watch battery a chip programmed by Audrino. But I was thinking if there is some sort of mini lever arms or somehow rig a magnetic reed switch with a magnet an use the polarities to push pull the lid? I'm just having trouble with the design, getting very frustrating. I attached a picture of a very very quick doodle of what I mean. The top design is with the Velcro idea. Thank you so much, really hope I learn something from you guys and others too!! Picture of ideas: http://i.imgur.com/pREJ9O3.jpg Thanks again! :D sorry for long message!

From New ScientistKATHERINE AULL's laboratory in Cambridge, Massachusetts, lacks a few mod cons. "Down here I have a thermocycler I bought on eBay for 59 bucks," she says, pulling out a large, box-shaped device she uses to copy short strands of DNA. "The rest is just home brew," she adds, pointing to a centrifuge made out of a power drill and plastic food container, and a styrofoam incubator warmed with a heating pad normally used in terrariums.In fact, Aull's lab is a closet less than 1 square metre in size in the shared apartment she lives in. Yet amid the piles of clothes she recently concocted vials of an entirely new genetically modified organism....Read the whole article in New Scientist

I know the title must sound odd, but this is actually a sappy, and in my opinion original gift idea for a female. Said female is significant. Need I say more? Anyways, I was wondering if there was a material that held a scent particularly well other than just normal fabric or something. Here's the idea: Have a pendant: small or large, really doesn't matter, that I can spray with my cologne, since she really enjoys it, it will hold the scent? ' This is just an idea, I did a little research to no avail, because I realized that this was just a little.. odd. XD Would really appreciate some fellow brainstormers. If worst comes to worst I was thinking I could actually take some of the cologne and have it in an intricate little glass vial and hang it from a pendant. Thanks all for your time and consideration, Roddie

We bought our house in April '96, and our dog Ted was born in Feb '96. My dog has been diabetic for several years now. His sister Ewok of the same litter has already passed away after suffering from Diabetes and Cancer. At one time Ted weighted 52 pounds (pre-Diabetes)..his last vet visit ( in the mid 20 range) , which for a Chow / Spitz is about 10-12 lbs. under weight. My elderly neighbor is always sneaking him food. I've even talked with his "Diabetic" Wife about this. He will lie to my face saying stuff like " Oh I only gave him a couple Milkbones ". Just today He says he's got some bread for Ted (our dog) . I told him as I approach that I am just going to pick it up and throw it away; Only to find a Glazed Chocolate Donut along with 10 small Milkbones and bread crust. I really am out of options here. Vetsullin is up to $37.00 a vial; and Ted's getting 20 Milgrams x 2 a day. Any suggestions?.....

Hello, currently performing operation "shoe candle" , for yowee. this operation is basically videoing the destruction of various fruit using flash powder or hmtd in a small 1-2ml glass vial. now, i have chosen my prefered explosive to be flash powder because after seeing the damage hmtd does when detonated in this way, i became frightful for my own safety, considering it lifted 1kg of dirt 30cm into the air and destabilizing it and making it fell as if it were dug up and loosly fille din again. ANYWAY i have come across a slight problem because i cant readily make aluminim powder enough to experiment with flash powder concuctions, and also i have about 4kg of finely powderd potassium nitrate lying around, wheras permanganate costs $10 for 25g at the pharmacy i would like to ask you instructables members, would flash powder made with potassium nitrate combust better than flash powder made with potassium permanganate the current mix i am using is 3 parts permanganate / 2 parts aluminium powder/ 1 part sulfur apparently this is the recipe for the old M-80's firecrackers i want to know if a equal or more powerful mix can be used by using potassium nitrate whoever answers will receive a best answer from me
Question by oldmanbeefjerky | last reply
The winter holidays are upon us! I can't seem to go anywhere without being accosted in several senses at once with a frantic plea to "BUY, BUY, BUY!" Advertisements for various sales splash across my field of view, blaring pop versions of holiday songs reverberate against my eardrums, and obnoxious clouds of synthetic fragrances waft, uninvited, into my sinuses. Maybe I'm an idealist, or maybe I'm just a curmudgeon... but I don't understand how a season of giving meshes with a season of commercial overconsumption. If I thought hard about it, perhaps my aunt Ida really wouldn't be thrilled with the box of assorted oversalted meats, plastic vials of suspiciously labeled "seasonings", and cheap imported mugs with images of football playing reindeer. But if the tacky mug set is the only piece of kitsch in an entire department store that fits in my budget, how much choice do I have? Lots, it turns out. Handmade gifts have become increasingly popular in recent years, and it's easy to see why. They're individualized and unique, they tend to use fewer resources and produce far less pollution since they're not made in a factory, they can be created with attention to detail and quality, and can cost little more than time and thought. In this economy, most of us have limited funds. Even if you're fabulously wealthy, a thoughtful handmade gift from you can mean more than a pricey basket that took no more though than whipping out a credit card. If you're browsing Instructables, you probably already enjoy learning about other people's ideas and sharing your own. Whether you're a long term author or haven't yet posted your own Instructable, now is the perfect time to show us something you can make! Have you reclaimed wool from a thrift store sweater to make a set of mittens for your mom? Have you made a small batch of scented homemade play dough, or perhaps melted old bits of crayons into chunky, swirly new ones for a child in your life? Are you brainstorming a plywood and acrylic laser cut clock for a loved one? Whatever it is that you've made as a gift, we'd love to see it! If you haven't yet... there's still time to get started. This year, we have some fabulous incentives (as if you needed more reasons to make something for someone else). Win yourself or a loved one a new computer, iPad or camera to document future Instructables! We'll be posting the Holiday Gifts Contest page soon, so be sure to keep an eye out. In the meantime, be sure to check out the Reuse and Sew Warm contests already running. There's still time to enter, and while you're there, be sure to vote for your favorites!

Sorry if it is in the wrong section of the forum. If it can be moved to a better place then do so. This is a quick mention to anyone that is playing around with any burners such as: wood gas generator bio-gas wood gasifier 'hobo' stove I am not severely concerned but it did happen, I think it needs a mention, as it is for everyone's safety. After playing with wood gas and attempting methanol creation from a small gasifier unit for a few weeks, I had started to realize that each day I had a most annoying headache / migrane in my frontal area of my brain / head. They ended up getting so bad that my body could not tolerate them anymore and started to go into shock, causing a rather painful, endless throwing up session for many hours each time even. It came to a point where after 3 weeks of playing with a bio-gas generator for about 4 hours a day had started to lead me into temporary blindness an hour and a half at a time. This was when I was concerned as I could not read any more instructables :( After a quick jot to the local doctors, I explained what I had been up to and I was correct. I had given myself the rather classic, and very close to death, carbon-monoxide poisoning where my doctor insisted I go to emergency at the hospital ( 2 hours away ) immediately and have someone else drive me. Pretty much equivalent to staying inside a garage with your car running for 5 hours, all the doors closed. I was very close to severe carbon monoxide poisoning and death. At the hospital, blood was taken, analysed, and they had discovered large traces of C02 that they attempted to flush with some oxygen, but this only works to a point and they mentioned that nothing else could be done apart from telling me not to use or be near any smoke sources for at least 3 weeks and I should recover fine. I am still playing with my wood gas generators, and attempting to make methanol, but these days, after 3 days ago, I take further safety precautions to make sure it wont happen again. Such as: ventilation / exhaust fan ( I WAS OUTSIDE WHEN I WAS POISONED! DONT TAKE THIS LIGHTLY! ) keep a distance, find a better way to ignite / extinguish the burner keep your face and body out of the smoke dont watch the flames / smoke from above for any longer than 2 seconds do not taunt the Criosote by-product of wood. I am not sure which is more toxic. The smoke or this. ( criosote / bio-crude, whatever you want to call it, it is the condensate of the burner unit containing more chemicals, very stinky) do not store criosote indoors withough a sealable container ( the smell likes to soak into things, like my kitchen ) if you know what you are doing, keep oxygen tank nearby use all protective clothing and masks, etc. There was a small arrogance in my head when playing with these units. And that is simply that I was thinking 'it is just smoke'. Wood gas generators are generating a much more toxic smoke than just sitting around your camping fire and should not be considered to be something to play with, without proper valves, pipes, burn off points etc. It contains on some scale: carbon-monoxide, methane, acids ( acetic ), tar and many other defects that will cause you issues if you are not careful. Keep it safe guys, this was a rather difficult one for explination, but I do not want someone other than me to be in that same sickness / position as I was with the poisoning, as it is the most painful experience I had yet had. Worse than me hitting a tree head on at 80km/h. Worse than falling 2 stories off a cliff onto rocks. Worse than being hit by a car and thrown over it's windscreen. Worse than the feeling of an unsuccessful home made rocket launch. All of these above I have had happen to me, and the poisoning was by far the worst and I was scared more for my life than than any above accidents. It is not a very nice feeling, it is a deathly, sickly, useless feeling, blindness is not far away from death if found in this situation. Oxygen / fresh air is the only thing to help you if poisoned, even if in hospital. Keep it safe guys. If you want me to write up a full on poster on wood-gas / wood-heater safety I can or even just a propper write - up on general safety with this smoke and the wood gas units etc. Ask please and I will. Hospital staff will most likely give you 'items of interest' for instructables if you just ask them too. I have a heap of things from a stethoscope to vials to 'red dots' for homemade ECG machines. They tend to like crazies like me that make weird stuffs .. i hope ive gotten the point across anyway.
