This experience need: finger battery and a single disk magnet. If you combine these 3 items on the scheme shown in the video, the screw comes into rotation with finger battery. In fact it is the easiest unipolar electromagnetic motor Faraday. It can be applied in various souvenirs and toys.
pretty cool... however i would have done it differently ... i would have attached some wire to each side of the motor, once it started spining too fast the two wires would fly out and hit some type of obstacle or complete a circuit that would disrupt the first circuit
