1. Toast always lands buttter side down.
2. Cats always land on their feet.
3. A spinning magnet can generate elctricity.
Tape a piece of buttered toast to the back of a cat. Tape two magnets on either side of the cat.
Drop it from a height. It will get confused and start spinnning rapidly, inches above the ground. Surround the cat with a loop of copper wire.
Perpetual motion! Free electricty!
