How cats drink

New York Times has a nice article about how cats use the front tip of their tongues to drink.

Writing in the Thursday issue of Science, the four engineers report that the cat’s lapping method depends on its instinctive ability to calculate the point at which gravitational force would overcome inertia and cause the water to fall.

What happens is that the cat darts its tongue, curving the upper side downward so that the tip lightly touches the surface of the water.

The tongue is then pulled upward at high speed, drawing a column of water behind it.

Just at the moment that gravity finally overcomes the rush of the water and starts to pull the column down — snap! The cat’s jaws have closed over the jet of water and swallowed it.

Here is a video of it.
