This is downright scary! A family was at a zoo the other day, and a little girl was beating her chest in front of the silverback gorilla. Apparently the gorilla didn't take too kindly to this show of dominance in the animal world, and took a flying leap at the window! The gorilla attacked with such force, that you can see the glass crack. Luckily, the glass held, and the gorillas left the area afterwards and no one was hurt!
