This is not an illusion. The magnet between the hand floats there touching nothing but air. The figure is about 7 inches tall and made of solid 99.99% bismuth. The walnut stand, (with either acrylic or oak posts) and magnet are about an inch and a half taller. Comes with a large new earth magnet above with several smaller floaters of various dimensions to experiment with. For the science aficionados, and those who love them, this modern bismuth metal sculpture is the perfect blending of art, chemistry and physics – a truly unique gift they’ll always treasure. Diamagnetic things repel all magnetic fields. North Pole, South Pole, it doesn’t matter. It’s a very weak effect and is barely detectable in most elements or molecules that possess this trait. Bismuth happens to be the most diamagnetic metal there is. A pair of bismuth crystals properly arranged in conjunction with a pair of magnets can reveal the force at work.
