An effect likely the Alan Warner Collectors have not even seen or heard about from the very early years of Mr. Warner's craftsmanship. The Magi-Meter measures magical powers and it is used to test the assistant to see if they possess the necessary powers to perform the next trick.
The magician shows that both the long and short cord run up and down freely yet when the prospective assistant pulls on the short cord it becomes longer and the long cord becomes short proving that indeed some magical power exists!
Beautifully made of wood and in beautiful condition. Includes instructions and a Rare if not impossible Alan Warner item to find for a collection.
