A stunt for the TV show "MythBusters" sent an errant cannonball through a California family's East Dublin home and into the window of a parked minivan a few hundred feet away.
Producers for the Discovery Channel show fired the cannonball Tuesday at the Alameda County Sheriff's Department bomb range behind the Santa Rita Jail when it misfired.
Sheriff's spokesman J.D. Nelson told the Contra Costa Times that no one was injured and the home's residents didn't even wake up.
Nelson is a consultant for the show and says the cannonball was supposed to go through a few water-filled barrels and a concrete wall. Instead, it passed over the barrels, through the wall, then through the house's front door and out a back wall before landing in the van.
