Canadian high school student Ann Makosinski demonstrating her body-heat powered Hollow Flashlight
At the tender age of 15, Canadian high school student Ann Makosinski has designed and built a flashlight powered by body heat. Her Hollow Flashlight secured her a finalist slot in the 15-16 age group of the Google Science Fair ahead of thousands of entries from more than 100 countries. My science project in tenth grade was a volcano that only worked about half the time, so I think she has me beat.
