This self-healing “skin,” funded partly by NASA and developed at the University of Michigan, is composed of two polymer sheets with a reactive liquid between them. When the sheets are punctured by a high-velocity projectile, a chemical within the liquid reacts with oxygen to seal the hole in a matter of seconds.
