I live in Switzerland! so I guess the waterproof clothing idustry here would love also the idea!
My only doubt is how to accurate control the water pressure. I guess I can find some pump compressed air that give me a lecture of the pressure I'm applying ...
Thanks!

The paper surface is superhydrophobic. However, the external pressure on a drop of water (or a column of water) can destroy the superhydrophobic property and then the water will penetrate into the paper. So, what I'm trying to do is to compare different paper surfaces and see which one is more...
Thanks!
Yes, my aim is to improve the hydrostatic pressure resistance of different paper coatings, and I need an easy method to compare this resistance for different paper sheets.
If I understand you well you would attached somehow the paper sheets to the bottom of the column with some...
I need to build a customized hydraulic pressure resistance tester in the lab. The idea is to measure easily but with a good reliability the resistance to hydraulic pressure (either external pressure on the water drops or the pressure caused by a column of water for example) of different paper...
