A family at a zoo in Nebraska got quite the scare when they decided to check out the ape enclosure.
As the family took cell phone video of the gorillas, a little girl started beating on her chest.
In the video, you can hear a little boy tell her to stop.
Seconds later, a gorilla charges the glass barrier separating the family from the ape enclosure.
The gorilla ran with such force that the glass actually broke.
