This "Hutchison Effect" has been claimed for years, without any independent verification - ever. In fact, its originator can't even replicated [sic] it on demand. This has been investigated more than once, been part of documentaries on the discovery channel, but still never seems to pass critical muster. This is in the category of folklore. In general, the "American Antigravity" web site caters to such folklore and its enthusiasts.
