Paranormal Adept
At one time we could easily disprove that people could fly, then along came Yves Rossy. I knew an electrician once who was a solid old country no-nonsense kind of guy who told me about an incident at a shipyard where some guys were welding a huge steel plate with a high energy arc welder, and for some reason the guys arm slipped toward the plate with the electric line attached to it and it seemed that for a moment his arm went through the plate in a ghost like manner and people on the other side even saw it. Sure it's anecdotal, but solid matter is mostly space and the electron layer is the outer boundary between atoms, so who knows for sure that interposition of matter isn't possible with right technology?
There has been a great deal of research into sound wave bombardment and atomic structural rigidity. There is a pretty cool/entertaining UFO documentary called "UFOs: The Secret Evidence" that contains some unusual film/video documentation within it that supposedly shows solid metal turning very rubbery and becoming flexible due to this type of experimentation. Not sure if it's a hoax or not, but I have also seen water suspended atop what's being referred to as a "force field" in a Smithsonian Science publication.
