Shake it. Twirl it. Bounce it. Watch a bazillion shimmering particles flow. After the turbulence, the SWORLD will calm and the particles will settle. Within this shell you will see kinematic viscosity in action. Visualized currents in the sphere are beautiful and ever changing. Plus it’s just cool! Choose gold Mars or green Venus.
Keep out of direct sunlight and away from heat.
