Plasma - Archetypal Material

This exhibit is currently not on display at Technorama.
Solid, liquid and gas – these are the three states of matter which everybody knows about. However, 99% of the visible matter in the universe is in a fourth state – a plasma. In a plasma the atoms are ionized – that is, the electrons are either partly or completely separated from the atomic nuclei and move about freely. The Aurorae (Northern Lights), sunlight, sodium lamps, even ordinary flames, are examples of glowing plasmas. You can control the discharges in the biggest plasma ball in the world with your bare hand!
