Shake. Twirl. Calm. Bounce!

Get an up-close look at fluid dynamics with this beautiful bouncy ball filled with rheoscopic fluid! What's that? Rheoscopic fluid is a special material that is used to visualize liquid flow patterns like currents, turbulence, and laminar flow. The Sworld ball also has a glitter-like powder inside, and will turn into a mesmerizing and calming cloudy swirl when shaken.

It is honestly amazing to watch. The swirly fluid is completely mesmerizing and people love playing with these in our store!

Great for all ages.
