Physicists generate balllightning in the lab
Ball-lightning is described as a luminous phenomenon occurring during thunderstorms. It is a mystery, however, that they should be visible not as a brief flash, i.e. just for microseconds, but exist for several seconds, i.e. a hundred thousand times as long as a flash of lightning. Besides such famous figures as the Roman philosopher Seneca, Pliny the Elder, Charlemagne and Henry II of England, in modern times the Nobel Prize winners in physics, Niels Bohr and Pjotr Kapitza, claim to have observed this phenomenon.
