topology puzzle - without cut the rope, separate two rings hello I wonder whether this puzzle is possible to solve.
if possible, what kind of thing should I learn to solve this?
the problem is make left one to right one without cut the rope
only stretch and bending are allowed
I found out this puzzle here->(www.ocf.berkeley.edu/~wwu/riddles/hard.shtml/)


I wish this problem lead me to learn math intuitively.

This is a classical topological problem and magic trick.
The concept is fairly simple and the diagram is misleading. If you manufacture latex or plastic loops as per the diagram, it is an impossible task.
However, if you take a string then to create the loops, you need to tie 2 knots. That's the key. The idea is basically to pass one loop through the other's knot.
