Stack, Drop and Pop

The Stack, Drop & Pop! Activity Toy from Manhattan Toy Company is designed to engage little engineering minds, where exploring principles of gravity and motion are disguised as fun building cool stuff. Includes 30 pieces: spinners, funnels, a trampoline bouncer, three balls and simple instructions (probably written for the parents, yes?) This is a variation of the classic marble maze toy, but designed to be used by little ones one year and up.
