I know the new toy I need to get. Zero Toys have a smoke machine gun that shoots smoke rings upto 14 feet. Now combine this with the bioluminescent stuff you can add to water to make it glow brightly for 15 minutes, and it would look so cool.

Hmmm... I was looking for a link to the bioluminescent stuff, but I can't find it. I know a couple years ago it was available for sale. Anyone know what this stuff was called, and if it's still available?
