This is a ball thrower. Wnen you place a ball in the scooper and flick your wrist down quickly it throws the ball about 5 feet. Abby and I first desinged a device which could slap people but then we decided that we needed to make something that would actually be helpful in the long run. Thus came the idea of the ball thrower using some of the design ideas from the slapper. The Lastest Scoop is for people who don't have a hand but still have the motion of their wrist. All of the parts of this machine, exluidng the ball, screws and string, have been designed on the Rhino software.
