I was cleaning out my shop this past weekend and ran across 8 left over porcelain tiles from a previous project. From what I remember being told, FHM spawn on the underside of flat surfaces. I was thinking about using them along with some bricks to make a structure like this:
The tiles are about 20"x20" and 1/2" thick. I would use bricks to space them which would put them about 3-3.5" apart. I was thinking about making two sets of 4 tiles placed on one of the more gentle slopes. I was going to place the top tile at about 2' of water and go down from there.
