Step 4: Make a Wineglass Flashlight

Phosphorescent Flashlight
The green and aqua phosphorescent powders are bright enough that a simple glow flashlight can be made with them using a plastic wineglass. When charged with a UV light for 30 seconds, it will give out enough light for about ten minutes to read or easily walk around a totally dark room. It will then dim but continue to glow fairly brightly all night. While not that practical as a source of light, it is an interesting phenomenon.

The flashlight was made by first flattening the bottom by filling the inside bottom of the glass with a round plug of Oogoo. An Oogoo mix of 1 corn starch to 1 silicone caulk was used to make a flat and white reflective surface to take the Ooglo paint. After it cured, the bottom was then painted with two coats of Ooglo paint.

I wanted to keep the inside of the wineglass reflective, so I then then painted the outside of the wineglass with two coats of Ooglo. Over that I put a thin coat of white Oogoo to reflect back the light. Over that I did one more thin coat of blue Oogoo so the outside of the flashlight wouldnt be too bright to night adapted eyes.

The thumbnail pic shows the wineglass flashlight in daylight.

<p>I am wondering if you've used citrus solvent. You mentioned it in another oogoo instructable, but didn't really mention how it compares to the more toxic substances.</p>
<p>Citrus solvent works but it is more expensive and it can slow down the cure time and take days to lose its smell.</p><p>Naphtha is still the best, as it cures fast and mostly loses its smell overnight.</p>
What are the actual measurements for an ideal mix? I could imagine it being frustrating not having enough, or too much. <br>
How waterproof do you think this stuff is? I'm thinking of painting my dog's harness with this stuff so it glows in the dark when we run at night (bike lights are blinding and fly off - it gets expensive to replace them after a while!), but she goes swimming on the creek when we run. I'm wondering if the cornstarch will make it dissolve and fall apart if it gets wet repeatedly.
Instead of using cornstarch you could use Magnesium Silicate Hepta-Hydrate (talc powder). It does the job of transporting the water into the mixture, but is inorganic and thus not susceptible to degradation.
It also sets REALLY FAST.... just sayin'.
I have soaked it in water for more than a week. <br><br>It does not dissolve.
All of the phospho powders I found were sold by weight, and I was wondering if you could tell me approximately how many tablespoons, or fluid ounces an ounce as you purchase it equates to? thank you, that'd make it much easier to plan my project. Also, given that my &quot;gel&quot; may be thicker than your &quot;gel&quot; and thus may not spread as far, could you give me an idea of how far one tube of silicone goes, and about how much phospo what would require. The stuff is kinda pricey, and I can't afford to buy a bunch extra, even though the possibilities are endless! great instructable, which is par for course for yours from what I've seen. thanks again<br><br>also I found a supplier that claims a 14 hour glow here: http://unitednuclear.com/index.php?main_page=product_info&amp;cPath=28_45&amp;products_id=383
United Nuclear is a good place to find info and cool, obscure stuff in small samples, but for any larger experiments it is really expensive. Try sourcing the products you need elsewhere if possible. NurdRage has some videos on luminescent material, and he's a chemist who explains things well.
Actually it's a she.
One of my favorite things as a kid was a capsule with phosphorescent stuff at the bottom and a strong lens at the top. You had to keep it out of the light all day (by keeping the cap on it) then at night I would peer through the lens to see atomic particles leave a trail through the glow stuff (radium?) It was shaped like a little a-bomb with fins &amp; all.
Hey, how about magnetic Oogroo or Ooglo? Add fine powders of ferrous metals. Might be handy for some things.
Mikey77, <br>I want to paint my 4 house numbers. So where can a person can buy it all ready to use. <br>Richard
this is cool as<br><br>would mixing the Fluorescent paint and the glow paint make it any brighter?<br><br>and how much golw stuff would you need to make a thin bit of wire glow, eg, fillimant in alight globe?<br><br>and how is stuff go with heat?<br><br>p.s the ooglo suff is neat, good thinking
How can this article have no comments yet? There are some awesome possibilities here for making luminescent parts.<br><br>I think I'll coat my housekey with this stuff and see what happens.
i agree, infact a few uv led's as back lighting and this could be turned into a constant glow.
Can you make &quot;see the instructable on How to Be Creative&quot; a hyperlink to that instructable? I will search it but it would put your's over the top for user friendliness and quality. I am among a (hopefully) few lazybones who like to click the hyperlink rather than spend 2 seconds searching for it. I probably could have found it instead of typing this!!! Anyway great 'ible and great idea.

Nice instructable!<br><br>What about painting a wall or two in a bedroom?
I can see me getting in real trouble with this !
Why hasn't anyone commented on this? Its stunning! Good photography too. Nice job.
I was asleep when this was posted (I live in a different time zone). Sorry! ;-)<br>It is cool!
