With the small, fast-spinning gyroscope in this Gyroscopes and Flywheels kit, you can build models and perform experiments that appear to defy the force of gravity by balancing and standing upright when common sense would tell you they should fall over. Build a model of a break-dancer that uses the gyroscope to spin and balance on its head. Construct a gyroscopic vehicle that keeps its balance like a Segway but with just one wheel. Assemble a cool robot that can zoom along a thin rail on two inline wheels without falling down. Includes a 32-page, full-color manual with illustrated step-by-step instructions. Recommended for ages 8 years and older.
