(Scroll down for video) A group of chimpanzees raided farms in Guinea, in order to steal alcoholic drinks.

In Bossou, the raffia palm trees produce a sap that quickly turns into alcohol.

Farmers gather the alcoholic sap in buckets and drink them. Recently, researchers recorded 51 incidents in which chimpanzees raided the farms to steal the alcoholic sap.

The chimpanzees used folded leaves to dip into the buckets holding the sap and then licking them. Some chimpanzees preferred to drink alone while others drank with a partner.

The alcohol content of the sap is about 3.1 percent. Scientists estimate that the chimpanzees drank between a tenth of an ounce to nearly three ounces at once.

After drinking the sap, some adult male chimpanzees seemed anxious, moving from one tree to another in an agitated manner.
