The magician displays a white satin bag to the audience. Reaching inside he discovers the bag is empty. The bag is turned inside out revealing the inside (now the outside) is green in colour. The bag is once again turned inside out revealing a yellow bag! Next the magician turns the bag inside out again and is stunned to discover that the bag is now bright red! This is repeated again and the bag changes to black! The magician reaches into the bag and produces a small item, silk, sweets, shot glass, etc.
This is a great comedy effect suitable for children or adults which becomes more hilarious the more confused and frustrated the magician appears.
