Break the sound barrier!!

Well, actually most of us have broken the sound barrier. If you feel you haven't, then just carry out this simple experiment. Moisten a handkerchief with some water, now hold it from the opposite ends and whirl it in air so that the dangling corners wind up around the diagonal forming, kind of a rope. Hold it tightly along the corners, leave one of the corners and simultaneously whip it in air.

In the first few attempts you might not get any thing, but after some time, when you get the hang of it, you'll here a crackling sound. This crackling sound is due to the tip of the wet handkerchief crossing the sound barrier and the sound produced is a sonic boom!! The tip of the chief crosses a speed of 750 mph.

For those of you not able to get it right, you can go to ebay and buy a bullwhip for yourself. Bullwhips were used in earlier times to gather the cows, not by hitting them, but by whipping it in air to produce this crackling sound. But please play safe, a bullwhip or a wet handkerchief can cause a lot of pain if it hits you.
