In order to stump drunk people with a cork trick, you will need the following: 2 corks per person. Tuck the cork between the thumbs and forefingers. The rules are that you have to switch out the corks without using any other fingers, besides the thumbs and forefingers, and the exchange must be simultaneous. While bystanders are trying to swap them out according to the rules, you will need to rotate one hand. Grab the edges with your over rotated hands. It should look like your hands are interlocked. Then, when you pull your hands apart, it will seem like you performed the trick. However, the cork was never exchanged. You have to get the bystanders to believe that your fingers need to be interlocked to do the trick.
