Extra Sensory Perception by Mark Strivings - TrickBack in The Jinx and subsequently in "Annemann's Practical Mental Effects", Theo Annemann published an absolutely fabulous idea. It was a devious and incredibly simple design duplication. I first came across it back in the mid 80's. But there's just one problem. As published, I haveyet to find anyone who could actually make it work. I suspect that has more to do with the way that materials have changed since the days of Annemann than anything else.
