  1. High temps and pressures, like space shuttle re-entry or the sun.


  2. by putting grapes in the microwave

  3. Plasma consists of a collection of free moving electrons and ions - atoms that have lost electrons. Energy is needed to strip electrons from atoms to make plasma. The energy can be of various origins: thermal, electrical, or light (ultraviolet light or intense visible light from a laser). With insufficient sustaining power, plasmas recombine into neutral gas.

    Plasma can be accelerated and steered by electric and magnetic fields, which allows it to be controlled and applied.

    An example of plasma is a neon sign. Just like a fluorescent light, neon signs are glass tubes filled with gas. When the light is turned on, the electricity flows through the tube. The electricity charges the gas, possibly neon, and creates plasma inside of the tube. The plasma glows a special color depending on what kind of gas is inside.
