No. 114: Nov-Dec 1997
You now have an antigravity machine; any object positioned above or below the rings will be weightless!
This recipe is based on a claim by Finnish scientist E.E. Podkletnov at the Tampere University of Technology. Podkletnov discovered this amazing effect when researching superconducting materials, However, he used only a single ring, which resulted in a 2% weight reduction. Since antigravity effects are probably additive, it seems reasonable that fifty rings will create a 100% weight reduction. Obviously, more than fifty rings will be required to launch spacecraft from earth!
Sure, it's a wild claim, but NASA is checking it out at the University of Alabama in a project headed by N. Li.

Comment. Facetiousness aside, it is pertinent to add here that physicist P.M.S. Blackett once seriously hypothesized that a magnetic field is generated by a rotating mass, such as the sun.
