So recently, I discovered this: http://www.magicwhiteboard.co.uk/
It's a statically charged polypropylene sheet that sticks to walls, paper, etc. Apparently they retain their static for a long time.
How do they charge these? A giant Van de Graaff generator? Rubbing it against a large carpet? Or is the sheet charged somehow during the process of production?
