The term GLOWING PARTICLE can be summarized as a SPARK, which is a five-letter word. A SPARK is a small particle or burst of light that is produced by a sudden electrical discharge. Sparks are usually seen in the form of a bright flash of light and are often accompanied by a loud noise. Sparks are created when two objects with different electrical charges come into contact with each other, causing an electric current to flow between them. Sparks can also be created when an electric current passes through a gas or liquid.
