You really think so? Because, that is the first time I was introduced to it (that and Silver Dream). Later I learned that it was invented by J.C.
NONONONONO! lol
John Cornelius did NOT invent the muscle pass. Arthur Buckley (1890-1953) did. It's in his book, Principles and Deceptions.
John Cornelius pioneered just one of its uses- "the coin that falls up".
Unfortunately, DG didn't invent this use of the MP (penetrations through glass or objects), either.
Ray Kosby did a similar penetration in his coins through hand,
John Kennedy and
Jay Sankey both did a similar penetration for the final coin of his coins through table, and
Curtis Kam did a similar thing (he used it as a production of a bunch of coins from a wall).
These routines are all "pre-Quarters".
I have a penetration using the MP in my upcoming book; a coin falls through the lid of an Okito box.
Scott.
