I’m with the girl, I don’t believe that either, i doubt you could actually ever get a knot that tight simply by shaking your foot around, and i really really doubt that if it were possible, a human would have the amount of coordination and fast reflexes to actually do it that fast…

You never know there are many things people say a human cannot do but they find a way, coordination? Have you seen skateboarders or snowboarders, etc. I think this is real the knot does not look all that tight.

i know someone who can do that it’s soooooo cool
but he won’t tell me how he does it

There was a video in slow motion on youtube.com or myspace.com that showed how it was done. I don’t have the spare time or boredom to try this though
