Yeah, you read the title right. It’s called X-Flex bombproof wallpaper and based on PopSci’s test video I’d say it works. Sure, this isn’t a full sized wall, like you’d find in a building or home, but one can only hope that the wallpaper’s strength scales relative to the wall size.
Applying the X-Flex wallpaper is just like any other. Just peel off the plastic, expose the sticky backing and apply to your wall of choice.
