It’s hard to capture in a photograph just how pretty this little bouncy ball is. The ‘ribbons’ inside are presumably suspended in some kind of gel, which means when the ball is spun the innards move at a slower rate than the ball itself. It really is quite lovely to look at.
Particularly so when the sun is shining through it, as when I photographed it. Lots of lovely colours shooting through it. And it bounces well, which I suppose is the most important thing in a bouncy ball!
