|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.
|A solid that is lighter than air - SEAgel Aerogel||
Aerogel (aka frozen or solid smoke) is the lightest solid ever made. It is used for thermal insulation and by NASA to trap space dust particles. This video demonstrates SEAgel, which is so light it can be lifted with static electricity.
|Synchronisation of 5 coupled metronomes||
Synchronisation of 5 coupled metronomes done in Lancaster University, Physics Dep, Nonlinear dynamics and medical physics group.
|Spraying hot water at -20 degrees Fahrenheit||
When you squirt boiling water at -20 degrees Fahrenheit (-29 degrees Celsius) it instantly turns into snow (flash frozen).
|Chill A Coke In 2 Minutes||
Put it in a bowl of ice, water, and salt. The salt lowers the freezing point of water.
|Cymatics: Geometric Sound Patterns||
An interesting experiment which shows sand on a vibrating metal plate forming various geometric patterns as a result of changing frequencies. Warning: it is a good idea to lower your volume before watching this video.
|Pool filled with non-Newtonian fluid||
A pool is filled with a mix of cornstarch and water made on a concrete mixer truck, so it becomes a non-newtonian fluid.
