One screw, one battery cell, a few inches of copper wire, and a magnet.
1. Set the screw on the magnet, bend the wire.
2. Press and hold the top end of the wire to the top end of the battery, making an electrical connection from the top battery end to the wire.
3. Lightly touch the free end of the wire to the side of the magnet. The magnet and screw start to spin immediately. We can get ours up to 10,000 RPM in about fifteen seconds.
Is a espectacular experiment.
