Batteries? Not required to light up.

Best kept warm to enlighten.  It's not me I am talking about.  It's the "Hollow Flashlight", an invention by a 15 years old Canadian high school student, Ann Makosinski, that lighted up by the warmth of  her hand holding it.

Here is a video of her talking about her submission of the "Hollow Flashlight" for the Google Science Fair.

No batteries required?  Definitely, the torchlight of the future to have.
