A "MythBusters" experiment went awry Tuesday when the Discovery Channel's crew missed its target, and sent a cantaloupe-sized cannonball flying through a Dublin, California neighborhood.

Amazingly no one was hurt or killed, but check out the incredible path of destruction, and watch the news story after the jump.

The cannonball went straight through a cinder-block wall, then flew about 700 yards into a residential area, bounced in front of a home and ripped through its front door, then through a bedroom where a family slept. It exited the home, crossed a six-lane highway, hit the roof of another home, and finally slammed into a parked minivan.
