Girl Wins Google Science Fair and $25,000 Scholorship by Inventing Body-Heat Powered Flashlight
Meet Ann Makosinski. She's 15-years-old, from Canada and is probably smarter than you.
She entered the Google Science Fair 2013 with her project, to invent a flashlight that ran solely on body heat. No batteries needed! After she explains on the science-y stuff, she shows you that it does, indeed work.
Now if I can only get her to make a Lego that doesn't hurt when you step on it in the middle of the night, I think she'll have a billion dollar industry.
