Secretly dig your right thumb into the crayon.Keep hold of the crayon behind your back as you bring your right hand up to your forehead as if concentrating. Take a quick look at your nail – you will see bits of crayon in it and will know the chosen colour. Concentrate some more and then announce the colour.
