Got glow-in-dark paint? UV keychain flashlight? Combine the two. Imagine what you could build. Get UV LEDs from All Electronics or Electronics Goldmine. Get yellow-green "Night glo" Speedball(tm) fabric screen ink from art supply stores. (This is a very early test-video of mine from last April, shot in thumbnail mode.)

Yep, it works well with a 405nM violet laser pulled from a dead blue-ray. The LEDs and that laser aren't really UV, that's just marketing hype. It's visible violet light. Blue and violet light can cause fluorescence. The edge of actual invisible UV starts farther out, around 380nM.

TV without vacuum
unless it only works with certain wavelengths of light. (hence the UV LED) but you said you could charge it with incandescent light?
Sorry if im making a stupid comment, i dont understand much about it.
Wikipediaing now.
i never put that together - that "wave lengths" of light are only visable in a particular spectrum due to their size.
i seriously learn and understand more by watching/reading youtube/wikipedia than i did in highschool
Because its INTERESTING (TO ANY TEACHER READING THIS).
