I love sewer explosions that send manhole covers 150ft in the air as much as the next MythBusters fan. It was a cool experiment. However, I really, really want to talk about the truck bed liner.
The first response at our house- why aren’t they making siding out of that? I’m not certain pieces of siding individually coated in the truck bed liner would have the same explosion proofing effects; it may be that the entire structure needs to be coated in one continuous layer, but still- a bomb proof house. How handy would that be for the zombie apocalypse?
