Before demonstrating magnetic levitation this video shows a small magnet being cooled to a superconducting temperature using liquid nitrogen. Once cooled the superconducting magnet is shown performing magnetic levitation above a section of magnetic track as seen in the featured image.
Further in the video the magnet is kept longer at superconducting temperatures by building a container of liquid nitrogen around it. It is then seen being whizzed along by hand while levitating above, clinging to the side and hanging below, a Möbius strip track plastered in neodymium magnets.
