The Invisible Harmonica doesn’t use hidden electronics, portable speakers, or phone applications. This is a real harmonica that hides in plain sight and allows you to produce multiple tones from any borrowed object or even thin air. This devious device includes a complete tutorial video that gives you many routine ideas and options to produce this quirky effect. Perfect for close-up, parlor, and stage, The Invisible Harmonica is an offbeat effect that audiences love.
I am selling this because even though I like the trick, it is not for me. I have never performed it and have never used it. It is virtually brand new but technically I would have to say it is used.
Printed inside of the box is the link and password for the tutorial.
