EKVILI Steel Balance Toy, Balance Airplane, Decompressive Physics Toy for Office/Desk EKV-04

Classical things never fade. This is a wonderful balance toy popular in 1960s to 1980s. A slight push will make it rotate for a while. Great ornament to your desk or windowsill. This little toy does not wobble forever due the existence of frictions caused by air or contacting point. To play it, you simply push the sphere gently and slowly: 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 unbalanced.
