DUBLIN, Calif. (KTLA) -- A house in northern California was hit by a cannonball when experiment by the Discovery Channel show "Mythbusters" went a bit askew, the Alameda County sheriff's office said.
The myth was about whether other things are just as effective as a cannonball when fired from a cannon. Instead, the mythbusters found out how effective a cannonball is when it misses its target.
The cannonball was traveling as fast as a bullet when it bounced off a sidewalk, blasted through the front door of a house, and whizzed across the bedroom of a sleeping couple.
The cannonball went through the bedroom wall, leaving a 10-inch hole. It then bounced across four lanes of traffic and hit another home, before finally smashing into a minivan.
