I am not exactly sure if this topic if relevant to this thread, so sorry in advance if it is not. I am currently in the 9th Grade, my AP Physics class is doing a individual project and I have absolutely no ideas. I am thinking about a Gauss Cannon or something. Maybe a levitating device such as the proposed idea of how " UFO's" fly. Using a magnetic field. Any help would be asolutely fantastic, and great site by the way.
