Aurora Borealis Tube Display |
| A plasma tube is a vacuum tube containing colored gasses that are influenced by an external magnet that a person holds up to the tube. The plasma tube contains high voltages. Vivid streamers of electrified plasma demonstrate what electric discharges look like at various gas pressures. Plasma is the fourth state of matter. With a solid, liquid, or gas, electrons are tightly bound to an individual atom. However, electrons in a plasma can roam freely from atom to atom, carrying electricity. |
