Morphing pasta and beyond
Researchers have developed a method where they imprint tiny patterned grooves onto swellable sheets, such as flat pasta dough or silicone rubber, and watch it "morph" into spirals, tubes, twists and flowers. The method could lead to more effective food packaging by reducing packing space during ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)
