Such regenerating materials are equipped with tiny parallel tubes containing two chemicals that “bleed” when any damage occurs. As the two chemicals mix, they form a gel that spreads across the damaged areas, closing cracks and holes. As the gel solidifies, it forms a tough substance that restores the material’s original strength.
