Until now, the world thought cats drink like dogs. Dogs use their tongue as a spoon, collect water in it and move their tongue back in their mouth. A team of the boston zoo presented a study that proofed this theory wrong.
Cats use their tongue as a tunnel. They dip it into water and use the physics of liquid dynamics to suck it into their mouth. In the very perfect moment, they bite to stop the water in their mouth and drink it.
Thes phenomen was watched and explained by a group of scientists of the boston zoo.
The founder of the team, Roman Stocker, watched his cat Cutta Cutta and saw it forming a tunnel with its tongue.
It took the team multiple hours to create highspeed video material and they also used youtube videos for their studies.
It's not only house house cats that use this trick. Bigger cats like tigers use it aswell. Using the liquid dynamics shortens the process of drinking a lot what is very important in nature. Water spots are a dangerous place to stay at, so the animals got to drink as fast as possible.
To determine how good the cats know this trick, the scientists used a number called Froudenumber.
It desribes the hydrodynamic flow of liquids. If it is 0, the liquid doesn't flow, if it's 1, the flow of liquid is as fast as possible.
Every cat they watched had a Froudenumber close to 1.
The team of scientists invented a robot to imitate the cats behavior and test the hydrodynamic flow of liquids.
It looks like everyone of us got a little genius at home!
