Armor-Piercing Bullet Turned to Dust When Fired at Composite Metal Foam

Essentially a metal sponge consisting of hollow metal beads within solid metal, composite metal foam (CMF) generally retains some physical properties of its base materials. While its defining characteristic is ultra-high porosity, CMF boasts 5 to 6 times greater strength as well as over 7 times higher energy absorption than previously developed metal foams. Typically created by melting aluminum around hollow metal spheres, it is impressively 70% lighter than sheet metal and 80 times more energy absorbent than steel.

The foam is claimed to be non-toxic, resistant to radiation, fire and heat resistant.

    I know, let's make schoolbooks out of this stuff. Problem solved.

    Then, when the next second amendment activist Trump supporter decides to shoot up a school, the kids will have a better chance of survival.
