The audience are shown 3 leather
holders each containing a different coloured envelope.
You explain that one of the
envelopes contains a banknote and the other two contain nothing of value. Ask
two spectators to each freely select either the red, blue or yellow envelope.
After they check the contents of their envelopes and only find your business
card, reveal that the remaining envelope contains the banknote. The effect comes
complete with special leather holders, envelopes and detailed instructions.
