A group of scientists from Tel Aviv University has shown on the public a series of experiments with superconductors in a magnetic field, which demonstrated the potential of so-called quantum levitation. Quantum levitation is based on the Meissner effect, and a soaring of the superconductor in a magnetic field. Scientists were able to demonstrate the most unusual tricks, related to quantum levitation, using superconductors with different thickness and a combination of several different magnetic fields intensity and focus, that has caused excitement among the public. However, the practical use of quantum levitation is not for entertainment purposes is still very difficult, because not yet been developed to room temperature superconductors, and must use only those materials that exhibit superconducting properties only when cooling them to very low temperatures, using liquid nitrogen.
