Hi there,
I hate to burst some reader's bubbles, but most of what you've heard is modern marketing hype surrounding an invention that has existed for roughly twenty years (and in the case of multi-ball work, since about the 1500's).
What the Fushigi ball actually is, is a solid chrome sphere surrounded by a thin layer of acrylic or polycarbonate. Previous contact juggling balls were made of pure crystal, acrylic, chrome, rubber, or even wood! The original Fushigi ball was simply an acrylic contact juggling ball, but it had the unfortunate side effect of causing fires if left in direct sunlight, which is why they have now stuck a chrome ball in the center.
Just to be clear, there is no magic trick or gimmick, no mechanism inside that actually make it defy gravity and float away. This is a perceptual illusion called "isolation", which you can see in many Youtube videos if you search for "contact juggling".
I do have to say, though, that any acrylic ball, even a Fushigi ball, looks quite striking when maneuvered correctly. But contrary to what is implied in the commercials, be aware that the artists involved have put in many months if not years perfecting the visual aspects of this beautiful art form! And there's a reason for that: contact juggling is extremely addictive!!
