Build your own gumball machines and learn physics lessons in the process.
It's a gumball machine meets a marble run meets a roller coaster meets a pinball machine!
As they roll down the track, the gumballs perform cool stunts and tricks; add a pendulum, pulley cups, trampoline, and more to see these wacky stunts in action.
Each segment of track teaches a different lesson in physics, demonstrating principles like force, motion, momentum, gravity, energy, simple machines, and more.
Compatible with standard machine-size, 16-mm (5/8-inch) gumballs, the kit comes with a small supply to get started.
