A very mystifying close-up effect which you can present a a telekinetic mystery, or just plain magic.
Effect :- A metal Nut is threaded on a large metal bolt with a collar and dropped into a tube. A shake of the tube, and the contents of the tube are tipped to show the nut has magically threaded right off the bolt. And every thing can be immediately given for thorough examination.
This is not new, and there are several models of the effect available. This model is very well made, and comes to you at an amazingly low price, making it excellent value. Complete with illustrated instructions.
