rub a doub(le )

in the book: Best of friends from 1985 Dan Garrett wrote a rub a dub force by the name:
"Force-Ooth" (page 268)
In his method you force a different card from your hand.
In my version the card is already on the table Laid on another card
After you reveal 1 card take 2 cards together and put them on the table
rub a card and spread the top card to make it appear
A friend magician told me In the DVD devil's picturebook, Derren brown play with a very similar move (3 card routine)
have fun play with it and and keep the magic alive(:
