This afternoon, we spent a ridiculous amount of time learning about how to crack a whip. I'm not sure what the practical application is of this knowledge, given that we don't live on a cattle ranch and Harrison Ford pretty much has the market cornered when it comes to whip cracks in movie sound tracks and Jimmy Buffett songs, but we learned about it, anyway.
This is an excellent "How To" video on whip cracking. My kids found it quite interesting and entertaining. Now Thing 3 wants a whip for Christmas.
