An apple that defies gravity and walks a tightrope ó what would Isaac Newton have thought? Build a cute apple robot that walks along a tightrope. How? Thanks to the robotís main component, a motorized gyroscope, it can maintain its balance and perform this fun trick without falling over. Through five experiments, you can discover the astonishing powers of the motorized gyroscope and explore the physics behind its amazing behaviors. Experiment with getting the gyrobot to walk on the different included tracks and on a string, investigate the gyrobotís center of gravity, play a ring-toss game, and watch the gyrobot spin on a flat surface.
