My good friend Doug Gorman has featured this effect in his act for years and this is easily the most streamlined version. Highly Recommended! The effect that professionals have cherished for over 20 years can finally be yours! streamlined and entertaining twist on Nate Leipzig’s favorite effect Sympathetic Thirteen! Super Strong for Parlor or Stage- Easy to Perform-Totally Astounding. This is Jörg Alexander’s pet routine, finally published on DVD, with all necessary gimmicks! All you need are two wine glasses and a silk. An effect people will talk about!
