Introduction
In this article, I present a DIY hydrostatic pressure testing device (and test results for 30 fabrics) that allows me to measure the hydrostatic head of "waterproof' fabrics at home.
The device is made from readily-available and inexpensive parts. I also present my protocol for running the device and a discussion of some of the fabrics I tested.
