Here's an awesome weekend project that could leave you with a fearsome "Ping Pong Ball Mauler" capable of firing hundreds of balls a minute at your unsuspecting neighbors.

Christian Reed built it out of a poly drum and a homemade pneumatic device. He turned a standard shop vacuum into a high volume, low pressure system that allows his contraption to continually fire a constant stream of ping pong balls at a rate of hundreds of balls a minute. Best of all, all of the parts he used can be bought at any well-stocked home improvement store!
