Kabooom!!
Of course my wife didn't understand my cackling when I watched that video. She's afraid I might take Grandpa's anvil out from under the work bench and give this a go in the back yard...NOT!! I think I'd rather watch from a safe distance. Obviously the shooters shouldn't wear things like nylon or polyester, it would suck to get a static shock at an inappropriate moment. Try explaining that one to your life insurance company!!
Gotta give 'em credit though, sure looks like fun.
