Perfect Mental SHOCKER!!
Take a piece of paper out of a bag, cleanly hand it to the spectator.
You have a little contest in free choice.
Have them mix up e disks, each has a different shap on one side. They lay face down on the table.
THEY choose one disks for you & one for them & puts inside the bag.
ALL SEEMS FAIR SO FAR right?
They open the paper from earlier thats been in plain view, unfold it...........
Its perfect the symbols location matches!!!
Free Choice ! Super Clever! NO Switches!
