If you give a gorilla a screwdriver, he will first be afraid of it, and then ignore it.
If you give a chimpanzee a screwdriver, he will use it to stab or pry, as the need arises.
If you give an orangutan a screwdriver, it will disappear as soon as your back is turned, and then, after you have left for the night, he will use it to dismantle his cage.

The news drones do not seem to have picked up on one of the obvious points, though: Karta wasn't trying to ESCAPE, she was just having fun.
As far as I know, no one has ever provided an orangutan with a pile of Duplo blocks. Could be interesting...
