Solution to the “Self-tying” Knot Trick from TAM9
Posted by mattusmaximus on July 24, 2011
This is the solution to the puzzle presented in my previous blog post – Self-Tying Knot Trick from TAM9 – wherein I show you how to supposedly tie a knot in a length of rope without releasing the ends. Of course, it is a trick, so watch the video carefully to see just how the trick is done. And have fun with some friends, family, or (if you’re a teacher) students with this puzzle. It is a wonderful exercise in critical thinking!
One last thing: I cannot claim credit for inventing this trick. I learned about it from Penn & Teller’s old book “Cruel Tricks for Dear Friends”, so credit should go to them🙂
