What do you get when you combine a super-sturdy bouncing ball with our Pearl Swirl rheoscopic fluid? We’re not completely sure either, but we do know that it makes one really fun toy! The Pearl Swirl Ball is our new favorite toy at the Spangler Science office. Plus, not only is it fun to play with, it also demonstrates a fascinating lesson in currents and Newton’s First Law of Motion. WARNING: The Pearl Swirl Ball has proven to be highly addictive, so proceed with caution! Recommended for children 4 and up.

What's included?

• Pearl Swirl Ball, 100 mm, in assorted colors (pink, purple, green and blue)

What does it teach?

Just like our Pearl Swirl, the Pearl Swirl Ball is great for teaching the motion of currents. Bounce the ball and watch the swirling motion inside. Also, the continuous motion of the fluid, even when the ball isn’t moving, is a great visual aid for Newton’s Law that “...an object in motion stays in motion...”.
