When you dream, do you fly?

Hungarian photographer David Nemcsik has created a series called the "Levitation Project" where he invites his friends to answer the question "where were you in your last dream?" and then attempts to recreate the surrealism of experience by having them float in midair at the location.

Floating Water

Making water appear to levitate usually requires a strobe light to trick the eye. If you don't have a fancy system to control water flow, you can run water through a tube taped to a speaker playing very low frequency sound, and again use a strobe light to make the water appear to defy gravity. Or you can ditch the strobe, and sync the sound waves to the frame rate of a video camera to make water drops appear to hover.

Does this mean we get to fly?

Physicists have 'solved' mystery of levitation Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing ... the Casimir force, so that it repels instead of attracts. Their discovery could ultimately lead to frictionless micro-machines with moving parts that levitate. But they say that, in principle at least, the same effect could be used to levitate bigger objects too, even a person.

There is no support for this Israeli position.

There is no support for this Israeli position. If you do not believe me, then just look here and here. This girl seems to agree with me, but wants your input too [javascript required]. However, in all fairness, this guy doesn't think the Israelis have a leg to stand on, and this guy thinks its dope.
