Braided Stream Use a lever to change the flow of air through fine powder, creating channels that form along the path of least resistance. This process of forming and deepening channels mimics the formation of water-filled streambeds on Earth and on Mars. Streambeds have also been cut by lava flows on our Moon. See convection cells form and change in a deep layer of fluid heated from below. Cyclone Cyclones are large vortices of atmospheric pressure surrounded by wind.
Hurricanes are cyclones that originate over warm oceans while tornadoes form over land.
A pump at the bottom of the sculpture spins the fluid into a vortex. Vortexes are found in atmospheric storms on Jupiter, Mars and the Earth. Static Landscape Tip a large disc to allow steel balls to cascade over the surface, building up a static charge. Rub your hands over the disc to generate additional electric charges. The balls organize themselves into branching patterns that resemble lightning.
