This SWOLRD's shell is strong and resilient like you! You can bounce it. Give it a twirl and watch a bazillion microscopic shimmering particles flow. After the turbulence, the SWORLD will calm and the particles will settle.
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.
