- The rope must absorb solution well.
- It should not have a plastic core (check the cross-section of the rope).
- For a cleaner look and better bubble performance, sew the ends together with needle and thread instead of tying a knot.
- Recommended folded rope length: 25 inches (635 mm).
As an alternative, you can use a string of beads instead of a rope — this makes the trick look more elegant and theatrical in performance.
