Product Story
This is the expansion pack for The Any Surface Marble Roller Coaster that adds an acrobatic element to existing courses by sending marbles bouncing off a trampoline. Marble run builders can see the physics of projectile motion, elastic collision, and trajectory in action as they position the trampoline so that marbles fly, catapult up to a higher track, or bounce downward. The set includes 12 building pieces that form a repositionable trampoline and two marbles. Ages 8 and up.
