How do they do that magic trick?
The real interest in quick change is that we do not know how they do it. Many have pretty good guesses, but are not 100% sure. Like all magic tricks. Once you know how it is done, you loose interest. I have seen quick change done so well that it could not have been any of the methods that are claimed. That is why the magician’s code is to never tell how it is done. Enjoy and guess.
