If you are into uv light magic then check out http://www.biotoy.com
they sell a natural product that makes water glow bright blue in the dark - Bioluminescence!! ( no uv light needed)
though not intended for consumption the makers believe it to be safe to drink but do not yet have F.D.A. approval .
i find this quite interesting for use in combination with uv magic and got a good reaction from a mate when after drinking some of the glowing water the veins in my arm glowed bright blue!!
the water looks amazing when its in your mouth and i think a lot more effective than a plastic fluorescent cup filled with normal water
dont know how many times i'd like to try it though as the thought of looking like a blue ready- brek kid all the time doesnt really appeal
$9.99 a pop plus shipping
