Ball Kit for Bubble Tube
This kit consists of a second narrower tube for installation within the bubble tube, plus a set of balls. The balls rise quickly through the inner tube and fall slowly on the outside between both tubes. It creates a fascinating effect that encourages visual tracking.
Add additional visual interest to your bubble tube.

- 1 x methacrylate inner tube
- 6 x white balls
