An ancient story tells of a king in which everything he touches turns to gold. Now you can re-tell the story by turning a bronze coin into gold right before your spectator’s eyes. Show a 2p, rub the coin and it slowly turns into a £1 which can be passed around for examination but wait, there’s more!
Rub your empty hands together and another coin appears which of course can be examined.
With this versatile prop many tricks can be performed, close up, with devastating results.
