A child armed with a rock managed to crack a glass viewing window at the Oakland Zoo's bear exhibit, but the zoo insists the glass will not break before repairs are made next month.
The child, belonging to a visitor at the zoo, "repeatedly smashed a rock against the glass with such force that it shattered the laminate layer of the four inch-thick panes," the zoo said in a statement.
The zoo said "there is no way this glass, even shattered, will break," adding that the viewing window is bulletproof.

Another zoo guest reported the cracked window to zoo staff, according to the zoo.
A new glass pane cost the zoo $67,000. It is set to be installed the second week of December, the zoo said.
