دستمال ظاهر شدن تخم مرغ

Show both sides of a handkerchief to the audience. The handkerchief is empty, just as your hands are empty. Now fold the handkerchief cloth together, and an egg will magically appear; and you can casually pop the egg into your hat. That is not all, this handkerchief can continue popping out those eggs, repeatedly, over and over; until your entire hat is full of eggs. This is a simple yet impressive trick.
