Bulletproof technology has certainly come a long way since Marty McFly bluffed his way through that Wild West shootout, as evidenced by this incredible video of a bullet getting a taste of its own medicine courtesy of the next big thing in body armor.
Designed by Afsaneh Rabiei of North Carolina State University, the projectile-smashing material on show consists primarily of a super-strong yet ultra-light composite metal foam (CMF), made of hollow steel spheres – each measuring 2 millimeters in diameter – embedded in a stainless steel matrix. While you’d probably expect a bullet to make mincemeat of such a squishy substance, the foam actually absorbs the kinetic energy of the moving ammunition.
