Get a long length of "U" channel made of aluminum or copper. Take a molybdenum magnet (or any really strong magnet) and give it a slight push from the raised end of the channel. It will then accelerate down the channel, frictionless, as it levitates per Lenz's law. OR, put an aluminum disk on a thrust bearing shaft so it will rotate freely. With the end of a few inches of masking tape afixed to the magnet, spin the aluminum disk and lower the magnet to the disk and show how it levitates. Then, hold the magnet in your fingers and force it down to the spinning disk (without touching) and show how it slows to nearly a stop----and how disk brakes could use the same principle (no friction wear), with conventional pads "kicking in" for the needed final "stop".
