Superconductivity - Part 2 of 3

At higher temperatures, a magnet is shown to rest on top of the superconducting pellet. Once the pellet is cooled sufficiently, the magnet levitates above the pellet.

Vapor Pressure: Collapsing Balloon

Balloons are placed on the tops of two Erlenmeyer flasks, one containing boiling water and the other containing hot air. As the flasks cool, the balloon on the flask of water is drawn into the flask.
