Superconductor Meissner Effect Levitation

I came across this video illustrating the Meissner effect with a high temperature superconductor from one of my labs today. Pretty fun! Magnetic fields cannot penetrate a superconductor. In order to prevent the magnetic field of the suspended magnet from entering, the superconductor sets up and opposite magnetic field that suspends the magnet.
