The word plastic is a physical term (from high school physics) and it refers to the physical state of matter. Most of the time we think of matter as being solid, liquid, or gas. A plastic is a liquid that takes on a solid appearance at room temperature. It will melt if warmed sufficiently.

Nature invented plastics long before man came along.

Glass was one of the first form of man-made plastic. If you've ever seen window panes that are 2-300 years old you'll notice the flow lines; it is slowly feeling the effects of gravity.

OK, enough physics. I'd rather talk about beads.
