One of the best gimmicks ever created for predictions is the Swami Gimmick, or Nail Writer. Theoretically, the sky is the limit with such a gimmick, because it allows you to secretly make a "prediction" long after it is supposed to have been made, and after the outcome of the event predicted is known to you. With just a modest amount of practice, it is possible to produce mind-boggling effects with this simple gimmick. This is an adjustable crescent style gimmick, made of brass, to fit all thumbs and take various sizes of lead. Pre-fitted with lead, this writer includes two pages of detailed instructions.
