Light Up A Game Of Toss With An LED Ball

Feeling like a game of catch, but the sun's gone down? Try out this DIY ball filled with LEDs. They light up randomly as the ball is shaken up, like a bunch of angry fireflies trapped in a globe.

It's a pretty simple process: gather up 15+ LEDs (this one uses 150) and a 3V battery. Dump inside transparent sphere. Have fun! [Instructables via Make Blog]
