THE EFFECT: You ask the spectator 9-10 simple maths questions e.g. 2+2, 3x5, 9-7 etc. You then tell the spectator that you will write down the name of a vegetable on a piece of paper and when they say their vegetable, it will match and it does!
THE SECRET: The first thing you have to do is to write on one side of a piece of paper "CELERY" and on the other side "CARROT". You then ask them the ten simple maths questions to get their brain warmed up. When you ask them to name a vegetable 80-90% of the time they will say Carrot and if they don't, the odds are that they will say Celery instead. HOW COOL!
