Love the comments regarding uses of the thing...
"Strangling an enemy of the state."
"I can't see how you would ever get the cord wrapped back up into a bracelet shape, once you unravel it."
"If things are really bleak, you could hang yourself with it."

I want one made from synthetic spider silk or nanotubes. What?
