Sweet (Bonus - Birthday Card) by Diamond Jim Tyler - DVD
DJ's effect SWEET is one where an initialed coin or borrowed ring vanishes and reappears inside of a sealed sweetener packet that has been in view the whole time. This effect leaves them speechless or in some cases causes the onlookers to develop Tourette's Syndrome right on the spot!
As a bonus DJ teaches another reputation maker called the BIRTHDAY CARD. The birthday person selects a card and signs it and the magician has trouble finding it, so to divert their attention he presents them with a sealed greeting card envelope. He claims that inside is a birthday card. Instead they find a playing card with a different colored back with a personal birthday message. To their surprise it is their signed card!
Diamond Jim has used both of these reputation makers for over 15 years to slay spectators! The DVD was shot before a live audience and includes the necessary gimmicks.
