This is fun. Show three mini magic wands.
Picking one of them up you shake it to show that it makes a loud rattling sound.
You pick up the other two wands and shake them to show that they DO NOT make a sound.
You mix the wands up and ask that someone point to the 'Rattling Wand'.

They make the attempt, but no matter how they try or how slow you move the wands, they are always wrong!
