Shapeshifting memory plastic

Researchers have invented a new plastic material that can change into three different shapes based on heat. The chemical engineers from MIT and the Helmhotz Association of German Research Centers demonstrated a plastic tube with three "programmed" diameters (4.5 mm, 6.9 mm, 5.8 mm) that are selected by altering the temperature.
