The performer enters eating Pringle's Potato Chips and drinking a Coke. After "emptying out" the chips and "draining" the Coke, the performer puts the empty bottle, neck first into the empty Pringle's can. He has a spectator hold the can from the top and bottom, so nothing can get in or out. He then introduces a handkerchief, which he causes to vanish.
When the Pringle's can is opened and the bottle is "poured out" into the spectator's hand, the previously vanished silk is found to be inside.
This effect is an absolute crowd pleaser that you will be able to perform within minutes with complete success.
