KNEX TOP GEAR Car Darts Challenge Building Set

The Challenge: Build up two crash cars and then an incredible launching mechanism that blasts them off toward your target!  Play alone or against a friend to try to score the most points!  Place the buildable front-loader on the bullseye, or haul the launcher around to your next demolition site just like on the show! 

Set includes a label sheet to customize your build, and a full set of step-by-step building instructions. 
Ages 7+
