Solid, liquid and gaseous aggregate states of matter have been known to man for centuries. However, there is also a fourth aggregate state, which is plasma! Stars, interplanetary and interstellar space are in a state of plasma, while on planet Earth plasma occurs as a rare natural phenomenon. It is estimated that about 1 % of matter in the universe is in the usual three aggregate states, while the rest of about 99 % is in the plasma state. Plasma can also be created artificially, and today it has great applications in physical chemistry, technology, medicine... Find out how you can make plasma at home using a microwave oven and a single match and how this plasma differs from the plasma that exists on the Sun.
