      Just needs a supply of Dioxygen difluoride Chlorine trifluoride [ref] which when spilled in large quantities “burned its way through a foot of concrete floor and chewed up another meter of sand and gravel beneath”

        A quick visit to wikipedia gives me this lovely paragraph which makes me nervous:

        The other main property of this unstable compound is it’s oxidizing power, although most experimental reactions have been conducted near -100 °C (173 K). Several experiments with the compound resulted in a series of fires and explosions. Some of the compounds that produced violent reactions with O2F2 include ethyl alcohol, methane, ammonia, and even water ice.

        Flourine is really scary stuff. If we’re going to toss some FOOF at the concrete, we could also use ClF3. Clorine Triflouride is another angry oxidizer that I’m pretty sure is hypergolic with sand of all things.
