Perhaps, but transporting dangerous materials through the mail is
prohibited in most locales. It's generally shipped by special courier.
Some of the examples given, though, of things which can ignite it are
sparks (sparklers are apparently a popular way of igniting the stuff), or
anything where you've got metal that's burning (an angle grinder, I
imagine, throwing sparks could do it).
