Exhibit Group D
September 2006, Paul Doherty
Air blowing over sand or snow creates ripples, waves and dunes which change the flow of the air. A complex process that makes interesting patterns.
Blow bubbles into the clouds and watch them spiral.
There is a commercial toy known as the Airzooka that blows vortex rings.
Volcanos sometimes blow vortex rings of smoke.
Most waves are created by wind.
Geyser physics, how to build a small geyser and how they work.
A model for how magma intrudes the crust of the earth creating chambers and volcanos.
Sea of Clouds
When water bubbles up through sand, quicksand may result.
(Vibrating Sandbox) The forefront of physics involves the study of "Soft matter" like the vibrating sand and air mixture in this exhibit. It also feels good!
