You don't believe what can happen when you visit lions on a safari [video]

On a safari in South Africa, visitors find out in the worst possible way how clever lions are. In a video that is going viral this week, a girl films from the car a group of lions resting. One of the cats is curious and approaches the vehicle - but what the passengers did not expect is what would come next.

Fortunately no one was hurt, with one of the passengers managing to close the door quickly. “My God, I didn't know they could do that!” Says one of the girls after the moment of terror.

And you, what would you do in this terrifying situation? Could he have acted so fast?
