Wandong Machine Simulator New Version Dynamic Art Wandong Device Stable Electromagnetic Drive Low Sound Suitable for Teaching
More stable, lower sound: This upgraded version of the perpetual motion device runs stably with lower sound, beating out the old version driven by noisy motors. Please watch our video to see how loud the device sounds when it is running. Caring customers please think twice before buying.
Fun Science Physics Gadget: You can literally watch the steel ball rolling all day long! The Magoog Perpetual Motion Machine uses electromagnetic induction and the law of gravity to make the ball "dance" continuously, attracting students to learn more about physical science. In addition, adults will also feel relaxed when playing with the ball.
Continuous 3 hours after full charge: Use the Type-C cable to charge the perpetual motion machine. Charge for 3.5 hours and play continuously for 2.5-3 hours. Note: Do not play while charging, otherwise it may not work properly. When fully charged, the indicator light will turn green.
Easy to Play: Just unbox and fully charge the perpetual motion machine toy, then turn it on with the smart touch, put a metal ball on it and watch it "dance and dance". Even adults will find it fun. No assembly or extra batteries required.
Need to know before buying: To make it appear to onlookers that gravity is enough to push the ball back into the tray, the charging port and LED indicator light are located underneath the base. The base has a nearly invisible touch-sensitive on/off button. The truth is, there is an electromagnet in the base that gives the ball an increased speed. We apologize for the potential inconvenience of a potentially confusing design.
