Stop what you're doing right now and WATCH THE TRAILER. You'll see a punched hole MOVE, BY ITSELF, from one end of a card to another. The card is signed and given away after the effect. Never, EVER, has a moving hole effect looked so visual. Porthole comes with the precision-made prop you need to perform the effect, and it will last a lifetime. The apparatus takes care of everything for you--no sleights required at all. Some more things to consider: You start and finish completely clean. You can perform "Porthole" surrounded. Easy To Do. No Threads - No Wires. You can perform this with playing cards, business cards or Similar. No forces - No Switch. Performance and explanation footage included in DVD. We shy away from using words like "ultimate" or "definitive" but it's hard to imagine a cleaner version of the moving hole plot. This looks as close to real magic as you can get! "Porthole is one of the coolest new effects I've seen in a long time. It totally freaked me out when Darryl showed it to me. I've Not been blown away by an effect in a long time and this one did it!"--Roy Kueppers. "The Best Animating Hole I've Seen. A Real Worker!"--Robert Barna - Professional Magician.
