Find tube where a magnet can just fit inside
Wrap wire all around it, attaching the ends to the LED light
Tape the LED light to the top of tube
Close tube with magnet inside
Quickly shake the tube so that the magnet moves up and down
The charges will try to oppose a change in magnetic flux. when the magnet moves up and down, this occurs in the copper wires. Charges will flow such that it opposes the direction of motion of the magnet, causing current to flow through the led, and so light!
