What changes the shape of a Styrofoam cup?
We can change the form of the cups by placing them into the rapidly boiling water and heating the polystyrene plastic to a point where it becomes soft and mold-able. Since the rubber bands are stretched tightly around the outside of the cup, this creates pressure in these areas causing the cup to deform.
