A modern classic, Nielsen Bottles are the undisputed highest quality vanishing bottles on the market.
Effect: Place a ketchup bottle into a paper bag. Snap your fingers, proclaim that the bottle is gone, but then reproduce the bottle from the bag before showing the bag empty. The audience will be unimpressed. Offer to repeat the trick. Someone in the audience is bound to say, “It’s in the bag,” to which you respond, “Let me look.” But they won’t take your word for it. The back and forth banter with the audience continues as you misinterpret their calls for you to turn the bag around, turn it upside down, etc. Finally, as if frustrated with how the trick is going, crush the bag into a tiny ball, proving that the bottle has vanished as an afterthought.
