How do ants drink water?

Okay this just came to me when I saw an ant on my desk and started wondering how he got all the way up to the 3rd floor. So how exactly do ants drink water? I have never seen an ant drink water, I have seen them eat a lot, but never drink. And when you think about it, when they do, how do they prevent themselves from getting sucked into the drop of water and dying, or being washed away in a tsunami that is a ripple in the water. But yeah, I mean they gotta get water some how, so I just do not know how they do it.
