People Spotted This Zoo Monkey Sharpening A Rock And Then Using It To Shatter His Glass Enclosure

If you’re like my husband, you hate zoos and think every animal trapped inside of one is wishing to break free. This story reaffirms his suspicions in every way.

Monkeys are some of the smartest animals out there, and so it figures that if any zoo animal could figure out a way to break free, it’d be a monkey.

Visitors at Zhengzhou Zoo in Central China noticed a cute little monkey innocently sharpening a rock in his enclosure. A little while later, that monkey showed everyone what he was really up to… planning his escape from Alcatraz!

The Columbian white-faced Capuchin used the freshly sharpened stone to break the glass on his enclosure. He fled the scene of the “crime” as soon as he realized what he had done.

According to The Daily Mail, a tourist by the name of Mr. Wang said that “the monkey was sharping the stone, then it started hitting it on the glass. The monkey scared itself away, but it came back to take another look and even touched it.”


So… was breaking the glass an accident? Or part of the monkey’s grand scheme? And was pretending to be frightened by the crash all part of his elaborate plan to avoid punishment? The world may never know!

According to the zoo’s staff, this monkey is unique from all other monkeys at the zoo.

“This monkey is unlike other monkeys,” said zoo worker Tian Shulia. “This one knows how to use tools to break walnuts.

When we feed walnuts to other monkeys, they only know to bite it. But it had never hit the glass before though.

This is the first time. It’s toughened glass, so it would never have got out. After it happened, we picked up all the rocks and took away all its ‘weapons’.”


It might sound impressive, but animals are far smarter than we give them credit for. Many animals use tools to their advantage.

For instance, chimpanzees use stone tools to create spears for hunting other primates.

It’s not just monkeys who utilize nature’s tools to their advantage. Crows use everything from twigs to their own feathers to get stuff done.

In addition, sea otters rely on rocks to hit abalone shells and crack them open.  Even octopuses with their eight gangly arms use tools – they use coconut shells as a type of portable armor.


The incident has everyone saying The Rise of The Planets of The Apes has begun… if that’s true, we better all re-watch the movies and take careful note!


Lucky for all of us, there’s video footage of the monkey breaking the glass using his sharpened stone tool. See for yourself below…

4 more reasons to fear the intelligence of monkeys:


Researchers found that monkeys create mental maps for efficiently traveling through the forest canopy from one fruit tree to another.

The same study found that Capuchins (the same type of monkey that broke the glass at the zoo in China) moved the farthest every day, covering over 1.8 miles (3,000 meters). By comparison, spider monkeys traversed 1.5 miles (2,500 meters) and howler monkeys covered .25 miles (400 meters).


In another experiment, monkeys showed the ability to recognize photos of their friends. They found that older monkeys were better able to understand the concept of a photograph compared to juvenile monkeys who were fascinated but puzzled by the photos.


Monkeys are capable of feeling self-doubt. Researchers discovered this by having monkeys play computer games, in which they noticed the monkeys would “pass” on questions they didn’t know rather than risk picking the wrong answer.


A 2007 study at Kyoto University found that a young male chimpanzee by the name of Ayumu was capable of recalling a random series of nine numbers, and then tapping them in the right order, even though the numbers had only been displayed for a fraction of a second before being replaced with white squares.

Many humans who have tried the same thing said they couldn’t do it with more than five numbers.
