Quantum Levitation Demonstration at North Museum 5
The North Museum of Natural History & Science in Lancaster, PA previews its newest attraction: a quantum levitator. It's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics.

Purchased for about $7,000 from Tel-Aviv University, the levitator is believed to be the only one of its kind in a United States museum.

The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of foam is placed on top and held in place with household plastic wrap. The disc is then dipped into a brew of liquid nitrogen (temperature: minus-300 degrees Fahrenheit).

This means you can make a train (or a car) run on a track like this without need for a steam engine! All you need is enough push to reach a calculated distance and an enough counter force to stop the train at a certain point!
