It's Too perfect; No Wires, nothing underneath, nothing on top, volunteer can do it. [edited] It cant be done.
I was thinking the same thing. The way it has been described, nothing in the water, nothing above, a spectator can walk around while you walk on it...I mean, there's got to be something to it unless you're doing the real deal. The Zaney Blaney levitation, probably the best of it's kind on the market, still has angles and needs special props to "prove" there's nothing extra, but they at least are honest about it in the description (something the SAM and IBM make you swear support to in their oath).
I don't doubt you've done amazing work here, Richards, but I just think you're leaving things out. I'm not saying you have to tip the method, but perhaps recognize that there is one. Personally, I hope for it to be as perfect as you say, and I wish you luck, man, though if it is, you don't need my blessing
