   dangerous hairs in a swimming pool
  Some people were saying that, if you dive from a high height (like 10m) into a swimming pool, and there happens to be a floating hair at the location where you land in the water, the hair will act like a knife and can actually cut your foot off or be lethal.I tried to find something about this on the internet but wasn't able to. Is there anyone here who heard about this and knows whether or not this is true?   
  Methinks that's bullshit. The physics just don't work out. And you'd have quite a few hair-related injuries in the news every year if it were true.   ;  Sounds like crap to me.Dave   ;  Well, some people are crazy.   ;  Let's refer to the tensile strength of hair.Please remove a hair from your head.Now try to break it.   ;  It's true. Pubic hair is the worst, since it is inherently more wrinkly and can transmit STDs.   ;  if only beakman was around to give us a definite answer...   ;Quote:Original post by RavuyaLet's refer to the tensile strength of hair.Please remove a hair from your head.Now try to break it.That doesn't say anything about what happens when it's floating on water and a high speed object hits it though.   ;Quote:Original post by jfclavetteIt's true.

My half-sister's cousin threw himself into a pool from a great height, got his hand cut off by a pubic hair and caught AIDS in the process.
