I remember seeing on TV a black and white clip of a scientist making
this small wood frame float using some kind of ion propulsion. But
that was when I was a kid, but now I saw a commerical for one of those
air puriafiers that does the same thing. They called it the Zenion
Effect, but searching that just brings up commerical sites, its just a
trademarked name. I was wondering what is the scientific name. And is
this something I could go to radio shack to build and experiment with?
