'MythBusters' cannonball goes through nearby house

An experiment for the show 'MythBusters' goes wrong after a firing test shoots a cannonball into the wall of a California home. Msnbc.com's Dara Brown reports.

DUBLIN, Calif. -- A "MythBusters" experiment went awry Tuesday, sending a cannonball blasting through a home, the Alameda County Sheriff's Office said.

Sheriff's spokesman J.D. Nelson told NBCBayArea.com that a projectile from an Alameda County firing range in Dublin missed its intended target and hit a home near Tassajara Road and Somerset Lane -- going through one wall and exiting through another.

The Sheriff's Office said it was a cannonball fired by a "MythBusters" crew that "took a few unfortunate bounces." It was not known what the experiment entailed.

The zany team on the Discovery Channel TV series attempts to verify or debunk urban legends, popularly held beliefs and movie scenes by conducting experiments — repeatedly warning young viewers not to try them at home or without a parent.

"MythBusters" has examined whether a collision with a bug can kill a biker (debunked), whether it is possible to shoot the hat off a person’s head without harming the wearer (debunked) and whether drafting behind a big-rig truck can improve a car's fuel efficiency (confirmed).

The exit hole from a misfired cannonball is seen after it traveled through a Dublin, Calif., home on Dec. 6.

The MythBusters' Twitter account retweeted a post from one of the show's cast, Grant Imahara, stating the team was to be working with artillery. That post (along with the photo) has since been removed.

No one was injured. Authorities were still investigating the incident. It was unclear where the cannonball came to rest.
