Ed Leedskrum (spelling?) created Coral Castle in Florida, Moved the dang thing and supposedly did it with anti-gravity machines. There are numerous other anti-gravity claims out there that claim harmonic and desonate frquencies can nullify gravity, and the evidence is video documented, BUT the experiments can never be reproduced.

Is there any work that proves or disproves the notes and designs of the machines he used. And I do think a 100 lb man (Ed's weight) can use block and tackle to move large stones. And there is even one post here that suggest you can move 2 tons on waterellon rinds.
