eldavojohn writes: Scientists have long been criticized of their inability to communicate complex ideas adequately to the rest of society. Similar to his questions on PBS' Scientific American Frontiers, actor Alan Alda wrote to the Journal of Science with a proposition called The Flame Challenge. Contestants would have to explain a flame to an eleven year old kid and the entries would be judged by thousands of children across the country. The winner of The Flame Challenge is quantum physics grad student Ben Ames whose animated video covers concepts like pyrolysis, chemiluminescence, oxidation and incandescence boiled into a humorous video complete with song. Now they are asking children age 10-12 to suggest the next question for the Flame Challenge. Kids out there, what would you like scientists to explain?
