In one of his TV specials, David Blaine stops to speak to a homeless man drinking a cup of coffee. He kneels down and takes the cup from him. After he gives it a few shakes, the coffee disappears right before his eyes, and the cup overflows with coins.
Take a look at David Blaine’s performance here.
How is it done?
The trick involves the use of a gimmick cup that you can make at home. You have to prepare the cup first before you can do the trick. This likely means that the homeless man in David Blaine’s video was an actor, but that’s getting off topic.
To do the trick, you need a sponge, scissors, and two plastic cups. View the tutorial video below.
