I interviewed Adam “Crack” Winrich at the Renaissance Festival. He does shows involving whips as well as fire.
Adam Crack practices two to three hours a day and has broken more than one world record, including the loudest whip crack. He got his first whip when he was about 7 or 8 years old. He says that the most dangerous thing about the job is risking cutting your skin open with a whip, especially with fire.
It was really entertaining to interview Adam Crack and I want to go to the Arizona Renaissance Festival again.
