Classical things never fade. This is a wonderful balance toy popular in 1960s to 1980s. A slight push will make it wobble for a while. Great ornament to your desk or shelf. This little toy does not rotate forever due the existence of friction caused by air or contacting point. To play it, you simply push the sphere gently: it stands on a small area so if push hardly or quickly it might will drop to ground which might will change its center of gravity and thus make it out of balance.
