Maybe you don't have any cattle to drive to market, but cracking a bullwhip isn't just for cowboys or Spanish vaqueros anymore. Just ask Indiana Jones--seen here in the whip crackin' trailer for the great first movie in the series, "Raiders of the Lost Ark." Read on to be like Indy and break the sound barrier with the popper, which is the end of a bullwhip. You'll be rewarded with a sonic "crack."
