Build your own gumball machines to perform super sweet stunts—and chew on a few physics lessons while you play! Try 12 hands-on experiments as you move the track segments around the base, creating new versions of your gumball machine. Create a pulley lift, pendulum, funnel, trampoline, variable-slope ramp, pinball launcher, and domino slide. Each segment of the track teaches a different lesson in mechanical physics so you can explore simple machines, force, motion, momentum, gravity, Newton’s laws, energy transfer, and more. Will your gumball successfully make it to the end of the track, or will you have to reengineer your gumball machine to make it work? Get started to find out! DIY gumball machine kit works with standard machine-size, 16mm (5/8”) gumballs and includes a small supply to get started. Includes 12 experiments and a manual. Caution: Contains small pieces. 16 ½” x 11 ½” x 3”. Ages 6+. Imported.
