I heard about this trick from David on the YouTube channel Magic Orthodoxy. I am putting together
the "ultimate magic kit" and I often rely on David when it comes to picking out a trick for the kit.
This is a nice little penetration effect, perfect for child just beginning magic. The only thing I
would say about this is the child needs to know a vanish or false transfer to really pull off tbe
effect. It won't work with a signed coin unless you can figure out a way to load it in the gimmick.
