Here we go. 18 lbs of screws being hung in the center of the bottom of the sink.
This actually has a few things wrong with it. First of all, in this pic, all of the 18 lbs is hung directly in the middle. With water, all the weight would be spread out across the entire length of 15 inches.
That means this torture test is way above what would be possible in real life.
Secondly, there would be several coats of Por 15 on top of the inside of the sink bottom, which would add strength, and a minimum of 3 not 2 coats of Epoxy on the bottom of the sink.
