Why couldn't I have been this inventive as a youth? Inventor Jörg Sprave has a habit of taking innocent objects and weaponizing them.  His videos are as entertaining as they are informative.  On his YouTube page, The Slingshot Channel, he takes ordinary, everyday items you find in most homes and turns them into potentially deadly weapons.  And we love it.  Below, he demonstrates his full-auto arrow gun and full-auto ping pong ball Gatling Gun.  Enjoy!
