That's right. Quantum Levitation. Think about that this morning. Your Monday will never be the same. Imagine the possibilities!
Here's a little bit of info on what you're looking at (via NPR through Wired News):
This levitation effect is explained by the Meissner effect, which describes how, when a material makes the transition from its normal to its superconducting state, it actively excludes magnetic fields from its interior, leaving only a thin layer on its surface.
When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place.
Scientists are constantly re-imagining how we interact with our world. They're not necessarily always inventing new things, they're completely deconstructing what's already here and re-understanding what it does or what it might be capable of doing. Science rules.
