As part of the World Science Festival going on in New York this weekend, The Flame Challenge (presented by Alan Alda) asked adults to come up with a way to explain what a flame is to an 11-year old.  The finalists will be judged by a panel of, well, 11-year olds, fittingly enough.  This particular animated video, “What is a Flame?” caught my eye, and my ear, with its graphics, comedy, and music.  But, does it meet the challenge?  We will find out on 6/2/2012.  You can see the other finalists on this page, and judge for yourself who should be the winner.
