What are some simple puzzles you think are hard to work out and are not well known?
E.G
Tie two ends of a rope together, place it on someone’s arm, get them to grab their side with the same arm and get them to remove it without letting go of their side or untying or damaging the rope.
Can you think of some other similar puzzles that are not too common and slightly challenging to work out.
