DIY BlackLight Contacts?

I know you can use Tonic water to make Blacklight reactive ice, But can you use this same method on soft contacts? I have no idea on weather tonic water is bad for your eyes, even less whether soft contacts are saluble enough for this trick to work. I figure a mix of 2/3 contact solution, to 1/3 tonic water soaked overnight might be enough to give your contacts a soft glow under blacklight. But I just dont know!Anyone willing to try this with some "overused" contacts?Glow Ice, How-to

Glow stick guide

Today I saw heaps of instructables about glow sticks. I searched for a glow stick guide and I found nothing. I can't be bothered enough to make a guide... So I'm just telling anyone who reads this topic; If you want to make a guide, make it about glow sticks.

Sodium Glow

Sleep is not restful here. The clouds serve as reading lamps. The sodium vapor glows. Cloudless, moonless nights, I can see my feet. The darkness will not come. Night escapes we tired city dwellers. The sodium glows just as bright as before. The ancients knew what night was, They couldn't see their hands in front of their face. They went to sleep at dusk. We modern night owls fire up the street lights. The ugly sodium glow.

using glow stick fluid outside the stick help

Alright need some help. im wanting to fill a bunch of test tubes with the fluid from glow sticks for my halloween costume this year. but for some reason after removing the fluid from the glow sticks and putting it in the tubes it does not stay lit for very long at all. im talking anywhere from 3-4 mins to 60 seconds. i have tried breaking the inner container before and after putting it into the test tube, and for some reason mixing the two after seems to have a longer life. moving and shaking the test tubes does cause the mix to glow for less time and im going to be wearing them so i cant have this. does any one have any kind of knowledge if this area? i could really use your help. any ideas on how to fix the life span?

Custom Glow Table: need ideas!

Hello everybody! First of all i'd just like to say I just made an account but have been using this site for years and love you guys =] I have this idea for a tv stand / table and I am stuck. attached is a drawing of my table (tried my best). The idea is a table made out of a recycled door as the table top, clear 6'' diameter and 2' long tubes as the legs, a liquid that reacts to blacklight inside the legs of the table such as laundry soap to fill the inside of the legs, and one small waterproof fan in each of the front legs to create a vortex inside the tube. So essentially I want a table with legs made of clear tubes with a glowing tornado in each front leg and a black light mounted under the table to light em' up! I need help figuring out what would be the best / cheapest material to use to create the front legs. Also what type of fan to use that is waterproof and will have enough torque to turn the water. Any help is appreciated!!

Fading Led (leds) inside computer looking like heart beat.

Hi! First of all I want to apologize my English but its not my mothers language. So what I would like to do is add warm white led (leds) into my computer what would fade out and fade in like really slow pulse. How this could be done. I can do basic soldering and schematics but the easier the schematic is the better :) And as cheap as possible because I'm not that rich at the moment. I have googled this a bit but found so many different versions and also they all faded so fast and I want my led (leds) to fade slowly. And because the idea is to but them to my computer this project would be using either 5 or 12 volt source. Thanks for all who can help me! Make

Glow in the Dark collars for Kitties

This is my first actual post though I've loved the site for a long time now. Anyhow I have two new cats, beautiful friendly, I love them to bits. The only trouble is they are very dark furred and there's been a couple of times they've hidden in plain sight. Me and my fiance are both worried about stepping on them I thought some glowing type collar would be cool. I've been searching the web for an answer and I can't really find anything so I decided to make one of my own. I have limited experience with electronics, I saw the post with an ewire I think it was called collar for dogs. I should be able to figure that out however the cat collar would be much smaller and I don't think it would comfortably sport the battery unit. I ditched the idea of glow in the dark paint (flaking and the cats probably wouldn't appreciate the fumes). I considered some glow-in-thedark hot glue.. but I don't know how to do that without making a collar look lik ea stiff, plasticy, mess. Maybe weaving some of the glow in the dark plastic laces into a collar kinda like the paracord bracelets? Anyone have any other ideas? Anyone heard of some glowing material or even glowing material dye? Thanks :)

Nitro Rc Glow Plug onborad glow plug ignition

So I'm relatively new to nitro rc and i had a few questions about on board glow plug ignition system  . I know the igniter is cheep and bla bla bla easy however... Can one be made ? I have often thought that i might be able to use a third channel off my receiver with a wire directly to the glow plug and at the flip of a switch the glow plug would ignite but i don't know if it would work and don't wanna spend the money on a receiver  to find out. Is there someone out there willing to give it a go and let me know?  Really my question would be at what voltage does a glow plug ignite? would a 7.2 volt battery do the trick? Are there any CHEEP systems out there?

how do you get glow pigment into quartz (or other stones)?

I've seen a few people selling "glow in the dark natural quartz."  Obviously they've taken pieces of quartz and somehow saturated them with glow in the dark pigment of some type.  So I'm curious now.  How'd they do that?!  Anybody have any thoughts?

Are there Phosphors that react only to specific frequencies of light?

Are there phosphors that only produce a color of visible light when struck by a specific frequency? If so, what would happen if this phosphor was struck be two beams of light at right angles, with each beam at half the "trigger" frequency?  If this would not result in an effective "trigger" frequency at that point, is there another method of achieving that effective frequency at a point, with two beams crossing at a single point, where the phosphor lies?

LEDs that get brighter when they're closer.

Ohkay, so I have an idea for a cute gift. The idea is to make two heart pendants that get brighter depending on how close they are to each-other. The problem is, I have no idea how to go about the dimming aspect. I've never even held a soldering gun, let alone used one. But I'd be willing to pick it up for this if I had a good tutorial/instructable to go off of. Even a general idea of what to look into would be great. I've seen similar things like the WiFi detector t-shirt at ThinkGeek, but again I'm a n00b when it comes to this stuff, so I don't know how useful that is when applied to something like this. Any help would be much appreciated, this is most definitely a burning question that's been bothering me.

Entire glow in the dark room?

Ignoring the practicalitites of expense, chemicals etc, would it be possible to paint and ENTIRE room, or at least a whole ceiling, in glow-in-the-dark paint? I'm thinking what would it be like to have an off-the-grid room that would have a useable amount of light, using glow-in-the-dark paint, for say 4 hours after sunset. Can anyone find any pictures of a room painted like this?

glow in the dark bike

After getting hit by a car while riding at night (even though I had lights) I am considering powder-coating the frame of my bike with a glow in the dark additive. I was wondering if anyone had attempted this before, and if you had thoughts on it. Also, can you powder-coat spokes? I know powder-coating the rims is bad because it interferes with the brake pads functioning, but I'd really like my bike to be as visible as possible.

Glow in the dark paint for styrofoam balls

Hello, I made a Zelda-style fairy (as seen in this guide https://www.instructables.com/id/Zelda-Style-Fairy-In-A-Bottle/). I was thinking that I might be able to give the styrofoam ball a little more character when not lit up if I could give it a light coat of paint. If there's a glow in the dark paint I can use for this, even better. I don't want to add so much paint that it will smother the light when it's switched on. I know spray paint will melt styrofoam, so that's out. Would I be able to sort of dry-brush acrylic paint used for miniatures onto it? I have a few pots of Citadel paint on hand, or I can always run to the craft store. Heck would food coloring work? Or is the whole idea more trouble than it's worth? Thanks for any help Dave

GID Vials, Tritium, TRASERS, Powders and Chemicals GLOW IN THE DARK!

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

Do people make requests for instructables too? + growing glowing geodes + making your own slime

Hey, I saw a instructible or two featured on here that reminded me of something that has prompted a question in my mind. Is there a typical way that people make requests for instructibles, aside from comments on existing instructables, or here in the forum? Or is this forum the typical place (I haven't scanned through to find out on my own)? Anyway, I have a request that I'll try to lay out here... In a badass local toy/education/science shop, they sell these kits of weird or "gross" science experiments. Like growing glowing geodes, making volcanoes, making glowing slime...stuff like that. The problem is, these kits are a bit pricey, but they DO have an ingredients list on the outside of the box. I took photos of the kits/lists in the store, with the idea that I could probably find info online to be able to replicate the "experiments" more cheaply by picking up the components elsewhere. I haven't gotten around to it, and so I thought Instructables would be the perfect place for people that would do the same thing and share the info to all of us. Specifically, I really want to do that glowing geode thing. Some of the other kits were pretty spiffy too, but I don't have the info in front of me to give you further details. (I'm sure I could google around, and eventually I'm sure I will).

Fluorescent Plants

Recently I presented a science teacher in my school, Mr. Zhang with the idea of growing plants with tonic water which contains quinine to see if they would glow under a black light. Today we saw that these bean sprouts had defused and taken in the tonic water, as a result the bean sprouts were fluorescent under the black light. I first chose the mung bean / bean sprout because I know that bean sprouts are translucent and it would be easier to see the glow, but now I want to find out if the seed will take in the quinine, and if so would the quinine be in the flesh of the plant at all. Another test that Mr. Zhang and I were considering was to use a tonic water in a hydroponic system to see if the plants utilize the quinine. Dr. Paul Williams suggested that I grow fastplants in the dark, because their stem is translucent is grown in the dark. (Mr. Zhang knew him from a workshop he did involving fastplants) I'll be updating this as I continue the study, I'll start growing very soon, as soon as I order the supplies that are necessary. The picture below, is of two mung beans, the one on the left took in the quinine, and the one of the right is normal.

Free idea for the glowing contest

Here is a free idea for the glowing contest. I don't have the time or inclination to make it, so y'all can fight over who does it if you want.Basically, the idea is just a yellow or pale green led or series of leds that glow in the same pattern as female fireflies, in the theory that this will attract males to your garden or whatever. I know that you are supposed to get rid of extraneous light sources to attract fireflies, but this sounds like it could work to me. Feel free to do it, so long as you give me credit for the original idea in the first line of the ible.Doesn't anybody like it...even a little bit...?

Assassin's Creed 1 & 2 Piece of Eden Apple

Everybody has been making their own hidden blades, but how about we try another item from the game? The Piece of Eden apples. They are glowing, futuristic spheres, which have the ability to control people's minds and cause intense Hallucinations. From seeing them, it looks like we can use the same basic Idea as this guy here with a Glowing box: https://www.instructables.com/id/Awesome-led-cube/ The Apple looks very similar in that the light emanates from behind the metal pieces, glowing at times, and you'd also need a way to turn it off and on, or for an added effect, but an electomagnetic switch inside instead of a pushbutton, where you can hold it and make it glow, but when you hand it off, it fades, or it only glows when placed on a base or something of the such. Just thought i'd get the ball rolling and see what we can come up with!

How to make an LED heart

Hello, I am designing and making a prop for a music concert and would like some advice on the best way to go about it. The prop needs to be a glowing/lit heart that starts off on stage as a series of glowing rods. The artist then constructs the shape onstage and it becomes this glowing heart. I am thinking of using some sort of plastic tubing and LED lights, but Im not sure how to construct them so that they can: - start of as individual rods then fitted together in a specific shape - they need to turn on and off an be able to have the batteries replaced. - must be bright red glow - lightweight and low heat. If anyone has some good ideas or advice on how to construct it I would be really grateful. Thanks guys!
