The actual German title translates to “Stages of Migration”, as it’s a “piece by piece” transposition of a glass and silk from one cabinet to another. No matter what you call it, the effect is novel and the mechanics behind the magic are ingeniously designed and perfectly constructed.
Here’s the routine:
The performer displays an upright cabinet with doors on the front and back which are swung open to allow a clear view through the obviously empty interior. A second cabinet is also displayed and the interior drawer is slid out to reveal a “Tom Collins style” cocktail glass that completely fills the drawer. The glass may be examined, along with a yellow silk. The silk is placed into the glass, which is placed back into the drawer. The drawer is slid shut. The doors of the first cabinet are also closed.
The performer states that he will make the glass and silk magically transpose from the one cabinet to the other, When the drawer of the second cabinet is opened, the audience will be surprised to find that the glass has vanished completely….but the yellow silk is still inside the drawer! (This will puzzle some magicians). The front door of the upright cabinet is swung open like before, and now standing tall inside is the empty glass! The transposition is not quite complete, so the door of the tall cabinet is closed once again. The performer then takes the yellow silk and places it into his hand. When his hand is opened, the silk has vanished!
When the door of the first cabinet is swung open now, the audience will be startled to see the yellow silk once again filling the glass! (And that part will really baffle most magicians, especially when you consider that no mirror glasses are used!)
I think this is one of Thomas Pohle’s most magical effects. It’s offbeat and surprising even to magicians. And the props he made are mini works of art. The mechanics are extremely clever. The drawer box is made so the drawer can be completely removed at the start…yet the glass will vanish as the silk remains. And the appearance of the silk filled glass in the tall cabinet is likewise very clever.
A very rare piece of magic. Boettcher’s instructions are dated 1990.
