The Maker Studio Gears Set by ThinkFun Games is designed by Engineers for Budding Engineers. The Maker Studio Gears Set inspires imagination and a love for engineering for your child. In this set featuring gears, your child will be able to build a race car, a cable car, a 3-wheeler and a motorcycle. For each build your child is given Engineering Challenges – experiment with friction, torque and propulsion as they engineer their solutions.
