Here’s a new take on protecting our soldiers from I.E.D.s; beanbags.
Build armor of elastic spheres that will bounce around in a chaotic fashion. Because the balls have different masses, they move erratically, and much of the incoming kinetic energy gets transformed into heat and noise.To get the physics that follows, keep one idea in mind: if you want to punch someone out, you don’t wrap your fist in a beanbag
