PLASMA

A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter." For example, because plasmas are made up of electrically charged particles, they are strongly influenced by electric and magnetic fields while neutral gases are not.

examples are
 the sun

• Welding arcs
• Lightning
• Auroras
• The upper atmosphere (the ionosphere)
• Stars and the Sun
• the solar wind
• interstellar gas clouds
• The fireball made by a nuclear weapon
• Comet tails

Supernovas are the most common cause of plasma disruption in the universe

here is an example

For comparison hiroshima bomb contains 20000 tons of TNT

and a full compressed supernova has 5 octilion million tons of TNT or (5000000000000000000000000000000000000000000)

You can trigger a Plasma explosion by positively charging a neutron to a deuterium oxide 

that will trigger a chain reaction which will deplete the neutron core so the nucleus explodes over and over
