Answer: While many plastic objects have little marks on them where the liquid plastic is injected into the mold, expanded polystyrene objects ("Styrofoam") aren't made this way. Instead, small granules of plastic are pre-treated with steam in a large hopper, which causes them to expand into little foam pellets.
