Re: Does a tie or wet towel crack at the speed of sound like a whip

Dear Lalit

Thank you for your question. I'm not quite sure if I understand it 
correcty though. Even if someone waves a wet towel very rapidly though 
the air, I've never noticed a cracking sound, have you? The top of the 
towel just isn't fast enough. If the towel hits something the situation 
is different but the "bang" is mainly caused by the body which was hit, 
rather than by the towel itself.
