Contraptions 50 Piece Kit

Contraptions 50 Piece Kit
Product Description
Contraptions are ramps and chutes, tracks and towers, tunnels, funnels, and more made by simply stacking planks. No glue or connectors are used, just gravity and imagination. Two specially designed balls provide bouncy action and surprising moves. Make the ball roll, twist, bounce, hop, and stop through your contraption. The contraption guidebook shows you how. It's packed with full color photos, tips, and instructions to build numerous clever contraptions, but the fun really rolls when builders design their own.
