try do a karate chop on a drinking plastic straw with its 2 ends held tight by a friend.
You just can't break it no matter how hard you hit it with your bare hand.
it's just too resilient, or it will just slip off your friend's grips.
However if you just thread the straw through a piece of ice (ring shaped ) and you do a karate chop on that piece of ice, the straw suddenly become so "brittle" and it will break easily.
Can anybody explain why this is so??
First i thought the straw was cut by the ice, but then on closer look i found that was not the case.
So i am looking for experts in physics to help. Anybody please?
