Satin vs. Satin

For a long time now I have had this plan to buy satin sheets, and attempt to slide across the aforementioned sheets while wearing a pair of satin pajamas.
A few days ago I finally bought satin sheets.
Now all I need is someone with a stop watch. A stop watch is required because this is a very scientific experiment, the results of which will more than likely end in some sort of scientific break through.
