  1. make your own!!!! by Unknown+Poltroon · · Score: 3, Interesting

    get some clean dry sand
    get old frying pan
    heat sand till it will scorch paper put on top of it
    get some wax/parrifin
    melt wax sparingly into sand, just enough to coat it
    let cool
    break up and repowder
    sand now stays dry!!!!

    THis might be redundant as i havent read the page yet.

    Would a windshield coated with the stuff not need wipers?

    on an aside, it would look just like real sand if it wasn't so darn blue.
