What do a bulletproof vest and a plastic milk jug have in common? Or a diamondring and pencil lead? Theyre actually made from similar materials. It all hasto do with materials science. Scientists study the microscopic parts ofmaterials such as plastic glass or stainless steel. They learn how each partmakes something hard or soft strong or weak or good or bad at carrying heat.Then they use that knowledge to create supermaterials. Supermaterials help makebetter sports equipment tinier computer chips and much more. Learn howscientists are using tiny particles to make big inventions in this glimpse intotwentyfirstcentury materials science. «
