   I listened to the podcast to this puzzle yesterday and took one night before listening to the answer.
   Now i wonder if someone wrote the solution i found.

   Steps to get the two ropes:
   1. climb rope 1 holding rope 2 at the highest point possible
   2. when you reach the top cut rope 1 and hold rope 2 so you don’t fall…
   3. climb to the top of rope 2

   i think to this point most solutions are similar.

   Now i need two points on rope 2, one point (a) very close to the ceiling and one point (b) a little bit lower.
   Now i start linking rope 1 to rope 2 on point (a) with one of those knods you can easily resolve by pulling on one end of the one rope. i let the longer part of rope 2 be the one to pull on.
   The shorter end of rope 2 i tie on point (b) of rope 1.

   Doing it this way which is possible(i tried it) i build a bridge.
   Now i can cut rope 1 between point (a) and point (b) without falling.
   Climbing down and pulling the longer part of rope 2, i resolve the upper knod and both ropes will fall down.

   All the rest should be easy.

   I hope you still read this and answer my question (did anyone else write this solution?)
   Im sorry if there are any mistakes of language.
   And i dont like writing my adress to a public forum but…
