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.

Old! And the source? #FakeNews! Even though it's apolitical. I'm totally leaving Soylent if this keeps up.

Well, what do you expect from desperate snowflakes. They're obviously looking for something to shield them from bullets that will be coming at them when Mueller comes after them.

Believe me, @BreitbartNews [twitter.com] wasn't great two years ago. Because Sloppy Steve was in charge. The Site is TREMENDOUSLY better now. It's not a guns thing, it's a MENTAL HEALTH thing.
