Look at the picture of the bubbler I posted.

The bubble on the bottom is what you fill with water. In my picture, there is a shotgun/carb hole on the other side of the bubbler (not pictured), so you fill that up with water, and the bubble on the bottom of the pipe, fills up with water. There is a stem tube (not removable) that goes down from the top of the bowl, down into the bubble part. When you smoke, it goes through that water cooling the smoke.

It's pretty much a cross between a pipe and a bong. You can use it dry or with water, doesn't matter.
