Quantum Levitating Toy Train

Back in 2011, Scientists at Tel Aviv University discovered how to levitate an object in what they called Quantum Levitation. There have been many entertaining applications of this technology since, but this new clip is worthy of attention. A Japanese scientist demonstrates what happens when you mix quantum levitation and model trains. You get a levitating toy train. So cool!

The hovering object must be extremely cold, hence the many applications of liquid nitrogen.
