Making waterproof & writable paper

  1. When cleaning up, Ramsey exposed the paper to UV light to dry it and make it easier to throw away. On a whim, she checked to see if the coating, which was enhanced with nanoparticles, made the paper impervious to pencils or ink.

    "For a minute, I was really disappointed. I could write on it all over the place," she said. "Then something clicked."

    It turned out that the coating, in combination with the makeshift apparatus, made the paper waterproof without making it waxy, brittle or changing its other characteristics. The original piece of paper has been submerged in water since June 6. It hasn't dissolved and Ramsey's original writing is still on it. She once even took it out of the water, wrote on it some more, and submerged it again.

    Now you don't need a bottle to get a message to someone. Well unless it sinks. nm

    That's really cool. Be sure to bring that substance with you in case you are stuck on an island in the middle of nowhere and needed help. Then you can send a SOS message on a coated piece of paper and for sure the person who run into it will definently be able to read the message. LOL... ^^"

    You could use it in the kitchen for recipes or something and not worry about getting food or wet on it. That's a good idea.
