Disentanglement - Teaser Balls

Teaser Balls
Designer:Anneke Treep & Christian Freeling
Craftsman:John Rausch
Material:Wooden Balls & Mountaineering Line

This puzzle exhibits the most desirable qualities for any puzzle. It is very simple with only one loop and one rope about 350mm long tied into a square (reef) knot. Neither ball will not fit through the loop in the blue ball. Yet it confuses even the most seasoned disentanglement puzzle solvers. Even those who manage to get it apart do so with such enthusiasm that they quickly pull the rope straight without paying attention to its position at the moment of success thereby making it much more difficult to put the knot back. You can easily make one for yourself - or buy one from Puzzle World.
