Learning Moment and Science

We had a great family learning moment and experiment I thought I would share.  It was so simple to setup that if you have the parts, it only takes a moment.

Over dinner, my son (3rd grade) talked about a video they watched at school about a young girl who invented a flashlight that worked by the heat of your hand.  I later found the video here: http://www.youtube.com/watch?v=9CCGUMkcbjg.  Big congrats to her, way to go!
