Glass so strong you can jump on it, a rubber-like coatingtough enough to absorb a bomb blast and protect a clay potdropped from 50 feet, endless varieties of plastic. Scientistsand engineers have created virtually indestructible versions ofcommon materials by manipulating the chains of interlockingatoms that give them strength—but have they made them tootough? Host David Pogue explores the fantastic chemistry behindthe everyday materials we depend on and how the quest fordurability can be balanced with products' environmental impact.
