90mm Coloured Crystal Ball — PMMA Contact Juggling Ball

Product Description:

The world bends around it.

This 90mm contact juggling ball is machined from optical-grade PMMA and saturated with rich translucent colour — catching, filtering, and bending light as it moves across your hand. Unlike opaque props, the colour lives inside the ball itself, shifting in intensity depending on the angle and light source. In sunlight it glows. Under stage lighting it commands attention.

At 90mm, this is a serious single-ball prop. The size creates the full convex lens effect that makes isolation work — where the ball appears completely motionless in space — visually impossible to explain. Heavier and more commanding than smaller sizes, it slows down every movement and demands precision.

Contact juggling is one of the slowest, most meditative forms of flow arts — the ball appears to float, suspended in space, as the hand moves invisibly beneath it. This ball is built for that illusion.

Available in multiple colours — select above.
