Waterproof Paper

The Blue Squirrel Newsletter this month offered me some waterproof paper - yes waterproof paper - if I invested in some of their software.
You can spray, dunk, submerge, drench, and soak the paper in sleet, rain, snow or even a lake and it completely retains its solid form. The Squirrel's didn't believe it either, until we tested Rite in the Rain's paper for ourselves. The squirrel's turned on the sink water full blast, gushing water all over the paper and couldn't believe what we saw. We could write on the paper with pencils while wet, and still read the written and printed ink. When we turned off the water, the paper was 100% still in tact as though nothing had happened.
Of course there are practical applications for waterproof paper - but you know, the more I thought about it, the more I remembered a story about the Fisher SpacePen and how the Americans spent millions of dollars developing a pen that would write in space; and the Russians used a pencil.
