I upvoted this video because the parents said no to some pretty cool science. Also you picked a decent video with some passion and preparation on the video shots.. You should leave comments in the youtube video this young man can see steemit! I am a bit concerned about the either in the water (yea, not the flames but the either!) but the stuff sticking around if your swimming lol... Probably no biggie. I just googled it and it seems to be petroleum based. That kind of sucks.

The liquid and dry ice is a clear winner though! This is the video that sold me on YouTube science..
