Hutchison effect

The Hutchison effect is an effect (or series of related effects) discovered by John Hutchison based on extremely high frequency (EHF) electromagnetic radiation. The effects demonstrated include levitation (from floating to flying up to the ceiling), materials being embedded in other materials (such as wood in a block of metal), and metal rods and extrusions transmuting, bending, twisting, exploding, and ripping as if made of jelly. Many parallels have been drawn between the Hutchison effect and the Philadelphia experiment.

Fairly little is known about Hutchison's actual setup, though it involves multiple Tesla coils, a, and EHF.

Theories
Hutchison himself advocates the effects having root in the ideas of zero-point energy, new forces of nature, and gravity/time waves. Proponents of the effect often theorize it has connections to scalar waves.

Criticism
Some claim that the videos released by Hutchison are frauds, using tricks to create the fantastical effects demonstrated. Critics usually point out that a few levitation/anti-gravity demonstrations are easy to replicate through some combination of glue, invisible strings, and electromagnets. The effects involving the metal extrusions are noticeably less commonly "debunked," as is the video in which he demonstrates a number of household objects moving on a piece of metal.
