"Thanks," he mutters, surfacing from under the table, briefly, to pull the iron out of the case and plug it in, letting it get hot. When he disappears again, he continues, louder, "It'd be easier to do, like, Whiplash's gear. You'd still need a disproportionately big power source, since arc reactors? Sadly not a thing, yet. But you could hide that in a backpack or whatever."

There's another pause, as he surfaces from under the table finally, a handful of tools spread out on the table alongside the mask, now, and then, "And sure, yeah, you could probably carry a camel pack around, with the ethanol gel, but ... yeah, still not so plausible." You'd still have a very short window to actually be able to use the Ghostrider whip.
