When I was in, I believe, High School my dad brought a friend of his over to our house. I can't remember his name. I believe he was a teacher, but he was also a magician. He performed quite a few tricks for me and I was really amazed. At that point I knew a little about magic and new some of the methods on a couple of things, but certainly did not let on. I think he did some form of "Oil and Water." That would have been the first time I saw this trick performed. The second time, I believe, was on the Tom Snyder" nightime show "The Tomorrow Show." It was performed by Derek Dingle. It blew me away. He may have also performed another card trick or two that night.
