The exit hole from a misfired cannonball is seen in the second story wall after it traveled through a Dublin, Calif., home on Cassata Place on Tuesday, Dec. 6, 2011. The cannonball misfired during the taping of an episode of the Discovery Channel show "MythBusters." The cannonball, fired at the Alameda County Bomb Disposal Range in Dublin, also damaged minivan parked a few blocks away on Springvale Drive. There were no injuries. Sheriff's spokesman J.D.

(CBS/AP) The "MythBusters" did some unplanned wall busting -- with an out-of-control cannonball. The Discovery Channel show was shooting a segment that involved firing a cannon on Tuesday when the plan went awry.
The segment took place at Alameda County Sheriff's Department bomb range in Dublin, Calif. The cannon was supposed to go through several barrels of water and a cinder block wall before hitting the bomb range. But instead, it sailed over the water-filled barrels and a concrete wall.
It then tore through a home and smashed a window in a minivan. Sheriff's spokesman J.D. Nelson told the Contra Costa Times no one was injured. The people in the home were asleep at the time.
