4+wiffle+Ball+Launcher

1.) The name of our invention is Wiffle Ball Launcher. It is called this because it launches wiffle balls. 2.) Our materials used in our project include, a leaf blower, duct tape, cardboard tubes, a plastic baseball bat, and a wiffle ball. 3.) Our invention is to be used for outdoor play. 4.) The way our invention works is we roll a wiffle ball down a tube. The tube leads into another tube known as the launcher. The leaf blower is putting a massive stream of air blowing through it. The wiffle ball will be flung on the jetstream and out the tube which leads to the outside.
