I came across this very interesting article please have a read below:

When the creature stoops to take a drink, for example, it must spread its front legs and lower its head to the water's surface. How a giraffe, the tallest animal on earth, then propels that water up its long neck to reach its stomach has been a mystery. Now, new research suggests the secret may lie with a simple device known as a plunger pump.

The spark that kindled this insight struck Philippe Binder last year in Namibia's Etosha National Park. He was sitting in a tour bus, watching a giraffe drink from a nearby watering hole.

"I thought, 'Wow, this is weird. Getting water up that long neck can't be easy,'" he said.

Binder is a physicist at the University of Hawaii at Hilo, where he studies nonlinear dynamics and chaos theory and seldom encounters giraffes. But while on sabbatical at the University of Cape Town in South Africa, Binder couldn't get the image of the thirsty giraffe out of his head.

"Physicists often have a childlike curiosity to know why things do what they do," he said. "I just wanted to understand how giraffes drink. It was sheer, pure fun."

He enlisted the help of Dale Taylor, a physicist at the University of Cape Town, and the two set about accumulating giraffe minutiae — neck length, esophagus capacity, length of typical drinking episodes — and searching for possible mechanisms behind the behaviour.
