well you don't make the holes so small that the water comes out in little
high pressure streams. The key is to make enough holes that the water comes
out slower at lower pressure. I use 3/16" or 1/4" drill bits and make LOTS
of holes. You can also drill the holes so that they point at the glass or
into the corner. Then the water currents will be diffused even more.
