Backyard Trebuchet

Well, the neighbors had their loud music playing one night to many, so some retribution was in order.

It was decided that it would come in the form of weighted tennis balls from above.  The method of doing so- a trebuchet.

It is over all about 8 feet tall.  The counter wight in sixty pounds of disks.  Average range is about 120 feet with a 12oz projectile.
