Engineering Makerspace Kinetic Machines STEM Kit

I'm selling a barely used Engineering Kinetic Machines STEM Experiment Kit! It's perfect for kids ages 6+. The kit includes 108 pieces and a 24-page manual to make five awesome machines and learn about the physics of force, motion, and energy. Construct a rubber band-powered car that zooms across the room, build a catapult and launch objects through the air, set up a launching device that propels a motorized car to a higher level, and design a wind-powered dragonfly model and a wind-activated sculpture to experiment with force.
