Giant 4" Prism Ribbon Water Ball. The Hi Bounce Prism Ribbon Water Ball is like a party contained in a clear ball. You can do so much with this cool stress toy. Bounce it on your desk or off the wall. You can also roll it across the office floor or on a table. It's filled with colorful confetti-like prism ribbons that add a little fun to your workday. Spin it to see the ribbons swirl around the clear liquid and watch as some the prismatic effect seems to change the color of the ribbon as it shines in the light. It's even great for playing a game of catch.
