Money Wise by Michael Murray

Effect: Opening your wallet you display 3 different coloured tags. One of which you explain is attached to a banknote. After some humorous by play you offer the spectator a choice of any two colours stating that your carefully chosen words will have subtly influenced their decision making.

One by one the spectators remove two coloured tags and are even given a choice to change their mind up till the last second. Needless to say no bill is attached to the selected tags.

Suspecting that none of the tags are attached to a banknote, you offer the spectators themselves to remove the remaining tag. This is found to be stapled into the banknote!
