A very mystifying close-up effect which you can present as a telekinetic mystery or just plain magic.
Effect: A metal nut is threaded on a 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 un-threaded itself right off the bolt!
Every thing can be immediately given for thorough examination.
This model is very well made and comes to you at an amazingly low price, making it an excellent value!
Complete with illustrated instructions.
