@MugsysRapSheet if you held a string up in the air like that and let go, it would collapse. The tension in the plastic is holding it up.

@ElleGray
That was my point exactly. It has nothing to do with the string being "stressed out" and everything to do with it being *stretched* out (you could have done the same thing with a single piece of plastic. It simply looks more "confusing" using multiple staggered strips.)
