Next-generation body armor could be made out of liquid

Body armor has evolved quite a lot throughout human history. Leather and metal were traditionally the two primary components for most of our early years, with the type and design of the metal changing based on the technological capabilities of the people at the time. Since then, armor has had to evolve to protect against more modern weapons like guns and explosives, Kevlar being the most popular option. However, it looks like body armor is evolving yet again, and this time its a liquid.
