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.

    It's in the Bible!

    "Ashes to ashes,
    Bullets to dust."

    Something like that. Book of Armaments, Chapter Three?

    And Saint Attila raised the hand grenade up on high, saying, "O Lord, bless this Thy hand grenade that with it Thou mayest blow Thine enemies to tiny bits, in Thy mercy." And the Lord did grin and the people did feast upon the lambs and sloths and carp and anchovies and orangutans and breakfast cereals, and fruit bats and large chu... [At this point, the friar is urged by Brother Maynard to "skip a bit, brother"]... And the Lord spake, saying, "First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who being naughty in my sight, shall snuff it." Amen.

    Could've swore it was part of the Book of Islam, according to the Runway2566 the infidel and coward. Book of Armaments, Chapter 2, Verses 9-21 [arstechnica.com]
