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.

    Considering what wikitionary returns for smake [wiktionary.org], whatever happens on IRC should stay on IRC, I reckon.

      Oh, you have no idea! Seriously, no idea! And you should probably not want to have one.

      So, now it's ok for me to use smake in scrabble?

    Hi there and sorry to barge in like this...

    Just wanted to make the case for linking the most recent journal entries on the right hand side of the main page to the actual post and not the journal itself. Why this matters? Because currently we get very strange link colors as if we had already visited some new journal posting while the only thing we have visited in the journal itself. So basically a case of link text saying A while the link points to B leading to general mayhem.

    Thank you've you've been a wonderful audience! (pun intended)

      That's been on my personal wishlist for a while now, yep.
