Instant Transferrence Of A Coin From One Hand To The Other

I attended a Magic Conference many years ago, and showed a simple trick I learned from my father. I was quite young at the time, and was astounded by the reaction from the seasoned practitioners looking on. It seems that they were approaching the riddle by searching for some complicated explanation. It was, in fact, "what you see is what you get", but they insisted there must be more to it. As you will see by the disclosure, it's a case of "the hand is quicker than the eye". This is a concept they wouldn't accept. "The hand cannot be quicker than the eye", they posed. "It's misdirection of some kind." Just goes to prove that sometimes the simplest answer is the best answer. They refused to accept my explanation, so I walked away resigned and just a tiny bit smug.
