Vanishing & Appearing Necklace by Mr. Magic - Trick
A necklace is shown on a display stand. Remove the necklace and place it in a bag with a mesh front. Cover the display with a hanky and place the bag containing the necklace in your closed hand. When you open your hand, the necklace has disappeared from the bag and reappeared back on the display stand under the hanky! Amazing and self-working. No skill required.
