Magician brings forth a small brass vial, a magic potion and some metal filings are placed within the brass vial and a drop of postion added to them. A cork completes the ritual. A slight shake and the filings are dumped out revealing that they have changed to gold fillings. These are returned to the vial and more of the potion added. The vial is stirred and finally a golden nugget is produced from the vial.
