Imagine this: a gumball machine meets a marble run meets a roller coaster meets a pinball machine. That's what you get with the Gumball Machine Maker! Build your own gumball machines and learn physics lessons in the process. A turn of the handle dispenses one gumball at a time out of the clear storage globe and down the track. The track is made up of different segments which can be moved around on the base of the machine to create an almost limitless number of different gumball machines.
