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.
Evaporating water can cool the head of a novelty store drinking bird, causing it to tip over and drink.
A magnet floating above a superconducting pellet is spun in order to show the dynamic response of the magnetic field expulsion.
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.
A 1-2-3 yttrium barium copper oxide superconducting pellet is cooled in liquid nitrogen and placed on an inverted foam cup. When a magnet is placed above the pellet, it is levitated by the superconductor.
Water in a sealed flask is made to boil below its normal boiling point by cooling the water vapor in the flask.
