One illusion that I know how to do is this one. First, you have a long sleeve shirt on. Next you get a pencil. Put the eraser part under your nostril. Put the led in your sleeve, but make sure no one sees you do this. You slide your hand up the pencil and you move your hand over to your ear and then you release. Voila, it looks like you're putting the pencil up your nose and then taking it out of your ear.
