Plasma globe. Close-up of a plasma globe. A plasma globe is a large glass vessel,inside which is a gas at low pressure. A voltage of static electricity is applied between the metal sphere at centre and the glass. Static discharge across the gas causes its atoms to lose their electrons,a 'plasma' state. When the nuclei and their electrons recombine,they emit a characteristic coloured light streams as seen here | |
