A cork is removed from a small brass can and four types of peas drop on the table; one is chosen by a spectator. Ask "Would it be magic if the only thing that comes out is the pea you selected?"All peas are put back into the can. The spectator says as instructed "I want my pea!"Cork is removed and warm water is poured into the spectator's hand (which is mistaken as pee by the spectator).
