Talk:Whipcracking
From Wikipedia, the free encyclopedia
The thing about the 3rd British Whipcracking thing is outdated, somebody fix it.
[edit] whipcracking tricks
last month I've stumbled upon a TV programme about some cowboy festival in America. A lady did amazing tricks with the whip including hitting a penny off the tongue of her partner. `'Míkka 18:41, 30 July 2007 (UTC)
[edit] Physics
The physics section mentions a vacuum, which is incorrect. The crack comes from the shock wave produced when the whip exceeds the speed of sound, and this does not create a vacuum. I checked the reference for it and it doesn't mention anything about a vacuum either. (Jatoo (talk) 12:55, 8 January 2008 (UTC))
