[QUOTE=TonyPTX;32279]Think of it this way…if you took a piece of pipe and put it in the water, but the end of the pipe was just above surface of the water. Now if you took a spoon, and scooped “water” from the inside of the pipe and put it in a bucket. Do you propose that you’d be able to dig a hole in the water?..no and why’s that? The hydrostatic pressure (at the depth of the other end of the pipe) would push water back into the pipe so that the level is always the same.[/QUOTE]
An explanation even a decky could understand.
