Being Giovanni, I didn't even watch the demo, I just bought it. Later, friends have told me this is
a very old trick that he used to teach when he lectured. Only difficult sleight is the one handed
knot, other than that, everything is doable. It's a little pricey, but I guess you are paying for
the guarantee that this is a worker. Giovanni is old school magic; not what's new and cool, gimmicky
magic. Instead, it is all based on basic magic fundamentals made to perplex and entertain.
