The kids participated in the Awana Grand Prix. It seems pretty easy to make one of these cars but we realized quickly that they are a huge pain! Getting the wheels to balance, to meet weight requirements etc. it was sort of harder then we thought. Despite that the Roper clan did pretty good! Jacob got 1st place in the design of his YouTube car and Katie and I got 3rd place in speed in the adult competition. No matter what though we had fun and that's all that matters.
