Someone has invented bomb-proof wallpaper. It is stronger than the wall it papers. Testing showed one thickness of the wallpaper was enough to prevent a wrecking ball from destroying a concrete and a brick wall. It’s a Kevlar-type material, in between sheets of elastic polymer wrap, which provides flexibility and strength. From PopSci, where they even have a video in action. Very cool. It’s called X-Flex and the Army is considering its use in Afghanistan. It comes in a peel and stick roll.

Edit: Got a family member that’s deployed and need a Christmas gift? There’s not much better.
