In the past few years, we have covered a whole host of cool levitating gadgets. You don’t always need a power source to get objects floating. This Pyrolytic Graphite Dimagnetic Levitation kit ships with a multi-magnet ring that generates a powerful magnetic field. You can simply put thin Pyrolytic Graphite sheets on the ring and give them a spin.
You don’t need any power source to get started and the levitated Pyrolytic Graphite sheets will spin for a while before stopping. Pretty cool, don’t you think?
