Chris' Science Fair '13

This year it was Chris' turn in the science fair.  He decided to prove perpetual motion.  It was a very elaborate set up.  Two different volume sized bins, 10 mouse traps and one catalyst (ping pong ball or a sponge).  With the toss of one ping pong ball all 10 mouse traps usually were set off.  But, if you tossed a sponge in there rarely did one even go off.  Can you tell me why?  Chris can!!

Here is Chris explaining to the judge the fine details of
perpetual motion.

Answering a few questions.

Awesome metal!!  Proud Dad!  They both had a great time!

Vanna White, I mean, Dad .... held up the props while Chris
explained to large gatherings of kids.
