Superconductivy Live!

It is always amazing to browse through YouTube, specially if you are looking for science material. Here is an example of superconductivity: take a superconductor and a magnet at room temperature. Nothing happens. Now cool down the superconductor using liquid nitrogen. The superconductor starts “superconducting” and boom! here comes in the Meissner effect. As always, a picture (movie) is better than a page of equations to show how wonderful physics is.
