- This reminds me. A while back, I saw a television show where a guy called
- 'Mr. Knot' demonstated the 'flying bowline'. He tossed a short length of
- rope in the air and caught it at both ends. Sure enough, it had tied itself
- into a bowline. It was not clear that this wasn't a camera trick, but it
- looked like an incredibly smooth camera trick.
-
- So can this be done?
-
- If so/if not, then what are the 'knots' which can be tied in this way?
-
- An interesting aspect of this question is that this is one problem about
- knots which knot theory looks powerless to solve.
