Two objects: a superconductor (the black brick) and a magnet. Magneto-optical film is placed on the magnet to visualize its magnetic properties. The magnet is placed on the superconductor: no sign of levitation since the superconductor is above the critical temperature. Pouring liquid nitrogen which has a temperature of 77 Kelvins (-196 Celsius).
