A system is provided for forming small accurately-spherical objects. Preformed largely-spherical objects (18) are supported at the opening of a conduit (16) on the update of hot gas emitted from the opening, so the object is in a molten state. The conduit is suddenly jerked away at a downward incline, to allow the molten object to drop in free fall, so that surface tension forms a precise sphere. The conduit portion that has the opening, lies in a moderate-vacuum chamber 40, and the falling sphere passes through the chamber and through a briefly-opened valve (30) into a tall drop tower (32) that contains a lower pressure, to allow the sphere to cool without deformation caused by falling through air.
