Here’s a great demonstration of a levitating magnet with 2 high-speed rotating cylinders.
Maybe someone can take this idea further and make us some hoverboards please!
While working on science museum exhibits in 1990 I came up with the above idea: it is known that a spinning metal disk will lift and fling a strong magnet. Therefore, metal rods with opposite spin will lift a magnet but WON’T fling it sideways. It works! I used “sched-80″ heavy wall copper tubes about 1-3/8
