discharge tubes
Ionized gas vessels
Discharge tubes are sealed glass tubes containing gas at low pressure through which electric current passes, producing light.
The glowing results from electrons exciting gas molecules.
Neon signs, fluorescent lights, and plasma globes all use discharge tubes.
Early physicists used them to study cathode rays and discover electrons.
