P2i is a company that makes a product called Aridion. It’s a “nano-coating technology” that applicable to a number of product and materials “making them liquid repellant without changing the look or feel”. It blocks liquids from getting into your technological devices.
The company released this demonstration video of CTO Dr. Stephen Coulson at CES 2012 performing a test of the Aridion with tissues. It’s pretty fascinating, especially when he puts the second tissue into the bowl of test water.
