A long time ago I bought a video, can't recall the title, which had several magicians performing some pet effects. I remember Derek Dingle performing an ace trick and I wonder if anybody knows what the effect of the trick was and if it had a title. Was this published or did he just do it specifically for this video. I remember the video also featured Bernard Billis, Paul Harris, David Roth, Frank Garcia, and Tony Hassini. At the time the video seemed more geared toward the younger magician, but I remember the Dingle routine being somewhat challenging for me then (classic Dingle) and I would like to try to relearn it now. I don't have the video now so any help is appreciated?
