Just when you thought you'd seen every use for cardboard boxes (i.e., containers) imaginable, along comes a company somewhat appropriately tagged Explo (seems they left off the "de" in the naming process) with an entirely new way to put the wood-pressed product to work.
Got about six million pounds of explosive powder lying around? Grab a ton of cardboard boxes and start shovelin'. Just be sure you don't hit something sparkable with that there spade or you'll be launched quicker'n a Congressperson can take a pay raise. And, make sure you company's execs are way out of the country (as in Korea) just in case a detonation factor kicks in.
