Are repelled when charged but collapse

When the charge escapes

The metal rod passes through a sulphur plug by which it is insulated from the glass jar in which the leaves are mounted. When the brass sphere and the leaves are uncharged, the leaves collapse and hang together. When some electrons are removed from the sphere, leaving the sphere and the leaves charged positively, the leaves diverge because of the repulsion between the like positive charges on them. If part of the positive charge is neutralized by adding some electrons, the gold leaves partly collapse. If all the positive charge is neutralized, the leaves collapse completely. If an excess of electrons is now added to the sphere, electrons will move to the leaves charging them with negative electricity. This causes the leaves to diverge again because of the repulsive forces between the like charges [2, C. 114 - 116].
