These cool new Rheoscopic Fluid Planets from Mr. Sci Science Factory are bouncy ball-sized planets filled with rheoscopic fluid (used to visualize liquid flow patterns like currents, turbulence, convection, and laminar flow) and a glitter-like powder that combine into a mesmerizing and calming cloudy swirl when shaken. It even bounces without breaking and includes a rubber ring to keep it on display without rolling away when not in use. Perfect for relieving stress, staring into at the office all day, fortune tellers, astronauts, and even kids. Check out the video below to see it in action. Cool huh?
