How to float like a stone
What goes up no longer has to come down. British scientists have developed an antigravity machine that can float heavy stones, coins and lumps of metal in mid-air. Based around a powerful magnet, the device levitates objects in a similar way to how a maglev train runs above its tracks.
The device exploits diamagnetism. Place non-magnetic objects inside a strong enough magnetic field and they are forced to act like weak magnets themselves. Generate a field that is stronger below and weaker above, and the resulting upward magnetic force cancels out gravity.
It won't be long, folks, until exeryday applications of this technology takes us into the Jetson age.
