Our Department of Planetoid shrinking used the patented Nano-o-Tron on a neighboring planet to create this wonderful rheoscopic toy. Rheoscopic, what? Rheoscopic fluid is a special material that shows currents. Within this planet's shell, you will see fluid dynamics visualized in spectacular ways.
Play with fluid dynamics.
See this world come alive.
Strong and resilient like you.
Take a breath and settle your particles.
