Play Sil-x 100mm Juggling Stage Balls have a very special feature; 1/3 of its internal volume is filled with a special LIQUID SILICONE. This gives it a very low center of gravity and makes the ball super stable on high throws and easy for foot catches and head rolling/balancing. The LIQUID SILICONE, unlike any kind of grain, slides perfectly inside the ball so that even when the ball is thrown with a spin it doesn't wobble in the air.
This 100mm version of the Sil-X ball is amazing for body rolls and has become very popular amongst contact jugglers. the latest generation of the Play Sil-X stage ball has a very slight matt feel which feels lovely in the palm.
