Magic straw: Scientists create self-folding, liquid-propelling straw from new material

Canberra scientists have developed a self-pumping straw that can propel liquid with a new material that fold into a tube when water touches it. Researchers from Australian National University have created a new paper-like material that responds to even a tiny droplet of water by folding into a tube several centimetres long. The material self-assembles itself into a tube-like straw and once assembled, the capillary delivers fluids.
