When penetrated by a tiny projectile at a high velocity, the material melted into a liquid that stopped the fast-moving object and actually sealed the hole it made. During their research, they found an excellent model material called a polystyrene-polydimethylsiloxane diblock-copolymer. Using two different methods, the team was eventually able to cross-section the structure to determine the depth of the bullets, and according to their study, the layers showed the ability to deform without breaking."
