The Bureau of Planet Shrinking used our Reduce-a-nator on a faraway planet to create this delightful rheoscopic sphere. Rheoscopic--what? Rheoscopic fluid is a special material that shows currents. Within this planet's shell you will see kinematic viscosity in action! Visualized currents in the sphere are beautiful and ever changing.
