You give a nut to examine and a shoelace. Thread the nut over the shoelace and have two spectators hold the ends of the shoelace. You cover the whole thing with a scarf or towel and, without the spectators letting go of the ends of the shoelace, you untie the nut from the shoelace and can give everything to be examined again!
- Extremely easy to do! - A 100% visual flash effect - It fits in the pocket!
