Mining the Walls

“In George R. R. Martin’s fantasy epic adapted as the TV series “Game of Thrones,” the 700-foot-high wall of ice — impenetrable, tall, northern — is protected by ancient sorcery. But all walls are built with an element of magical thinking. For what is a wall but wish fulfillment made concrete?†

So how does a wall blow up?

Or are we fed up with blowing things up, yet?
