In 1877, photographer Eadweard Muybridge settled a longstanding debate on whether or not a horse completely leaves the ground at any point during its gallop by taking a single photograph of a horse completely airborne. In the same way, photography was also used recently by a group of researchers to uncover the mystery of how cats drink.
Using high speed cameras, they discovered that cats touch the surface of liquids with their tongues (up to four times per second) before quickly pulling back up, causing a stream of liquid to rise upward. Before gravity pulls the stream back down, the cat closes its mouth around some of it, capturing the liquid. The process is quite different from dogs, which cup the water using their tongues and haul it back into their mouths.

Yay for the usefulness of photography!

… 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.
The cat laps four times a second — too fast for the human eye to see anything but a blur — and its tongue moves at a speed of one meter per second.
