Matchbook Flashlight

This is a matchbook flashlight that I made with instructions from the book "Show Off: How To do Absolutely Everything One Step at a Time"  by Sarah Hines-Stephens and Bethany Mann.  Simple, but fun.  ;)  Would be good for a group project for Girl or Boy Scouts, etc.  It takes two LEDs that I cannibalized from a string of on-sale christmas lights, one matchbook cover, and one watch battery.  The watch battery is the expensive part.
