could you break the glass around the crystal? i think that would make it cooler

You should try to mix in some fluorescent dye; from a highlighter or a spent 'light stick'. the fast crystallization might even allow several dyes in a swirl pattern within the bulb.....

I tried it with 3 UV LEDs, but it doesn't work like the bulb in the Video

THe bulb in the video is a UV bulb. Which, would not be normaly visable light, but the camera "sees" in a ifferent spectrum than we do. So, on a recording we can see it.

instant warm compress is sodium acetate i believe. its also the same stuff as in those instant hot packs for sporting injuries. you can get it from a chemists. yes it does stay solid. its not actual ice when hardened it is a compound that is similar to sodium chloride (table salt) but in a big solid block. so it will dissolve if it gets wet. LED's come in lots of different types with different power outputs. so the uv led's shown here are most probably high intensity ones which are several times brighter than a standard one. usually cost around $5 ish each. i havent seen high intensity uv ones before but i would assume they exist. just ask in places that sell electrical components or on ebay
