Scientists at BAE Systems in Bristol, UK have come up with a "shear-thickening" (or dilatant) liquid that can be combined with Kevlar to create a new, more powerful bullet-proof material. Similar to the "body armor" used by some Olympic skiers, shear-thickening material acts as a lubricant at low velocities, but quickly hardens upon impact. The scientists describe it as "bullet-proof custard," which shouldn't make us hungry but is for some reason. According to the company, recent tests in which a large gas gun fired metal projectiles at over 300 meters / second into both thirty-one layers of untreated kevlar and ten layers of k
