This came from an old magician’s estate purchase. Maker not known. No original instructions but we will supply something that explains the working if you are not familiar with this. The rings have some light rust as can be seen in the picture.
Effect: The Goblin Tube is a mini-miracle performed under test conditions. The basic effect is that the performer hands out a small metal tube for examination. Two metal rings and two pieces of tissue are also given to the spectator. They are requested to seal both ends of the tube with the rings and tissue, thereby forming a drumhead.
The magician then takes the sealed tube from the spectator; shows both hands empty; breaks through the tissue and produces a silk handkerchief!
Everything, both before and after the effect may be examined.
No silk supplied.
