See video Supercooled Beer

Similar to the demonstration of Supercooled Water, but this time with beer.

See video Cloud gravity waves

Gravity waves (not to be confused with gravitational waves) are waves generated at the interface between two media, for example the ripples created by a rock thrown into a pond. In the atmosphere, it is the result of air rising and sinking, gradually moving back towards its equilibrium point.

See video Supercooled Water

A demonstration of supercooled water 'snap freezing'. When water is supercooled it remains liquid below it's normal freezing point. Shaking it gently can activate the freezing process.
