Description Build this motorized marble run and learn some basic laws of motion. Place the marbles at the top of the circuit and watch them race to the finish until it starts again and again! Be mesmerized watching the marbles spin and spin and then disappear into the rotor, only to appear at the top again! Have fun playing and learning! Kids will learn interesting scientific facts while building and playing and they won’t even realise it. Children feel a real sense of achievement after building it and being able to play with it. Ages: 5 years and up.
