Turbulence in Earth's atmosphere causes weather patterns.

How it works

Spin the sphere slowly, then quickly and compare different patterns in the fluid.

Things to try or ask around the exhibit

What does the spinning globe look like?

Background

As you spin the sphere, friction causes the fluid to drag as it flows. This causes the fluid to move in a turbulent and chaotic way.

Finding the science in your world

Earth's atmosphere and ocean currents are affected by the spinning of the planet, which in turn affects weather systems and ocean temperatures.
