Bag Stab & Polymerization

A plastic bag is made of polymers, long chains of individual molecules called monomers. When a sharp pencil pierces the bag the polymer chains separate without breaking. The chains of molecules then squeeze tightly around the pencil creating a seal that prevents it from leaking. Polymers find use in our everyday life, from water bottles and Tupperware to tires for automobiles. The word […]

MEDIEVAL ENGINEERS: THE SCIENCE BEHIND THE CATAPULT
