KEVA CONTRAPTIONS 50 PLANKS

Recommended for ages 7 to 12 years      50 pieces     

Construct tracks, tunnels, funnels, ramps, and chutes. Bring your creations and innovations to life when you set the ball rolling! A skill developing set for sure! Kids build using trial and error and gain understanding of physics and engineering concepts. The equally sized planks seem simple to stack, but complex logic is required to complete a working ball track. Kids use fine motor skills to ensure their creations maintain balance and structural stability. No glue or connectors are needed, only simple stacking and gravity. If you reach an impasse in completing your contraption, the Idea Book will help. 50 pine planks and 2 balls offer endless contraption-making fun!
