Materials Science ... gel body armor!
I love to read about new technologies like this ... something truly futuristic ... a "viscous gel" in a vest that is fluid until struck or impacted ... then it turns to a hardened material. Afterwards ... it returns to a gel. Bullet-proof vests that morph ... very cool!
