At a Pavel lecture he presented a great effect for an on the spot stooge.....show a color wheel for paint color selection......containing 50 or more colors.....the kind that have a pivot point to swing out the various colors....

on the spot ask for a spectator to help...hand them the paint selection....on the first page it says "HEY...help me fool everyone....choose pink"....after they read that...have them scroll through all the colors....close it up ....and reveal the color they chose.....reveal any way you wish....Pavel used a balloon with a piece of paper in the balloon.
