A rocketship that puts out fires. Like a firetruck.

Probably the world’s greatest invention since lasers, definitely the awesomest thing that (unaccountably) has not been made yet.
Elon Musk: "I'm telling you man, soon as I'm done with SpaceX and Tesla it's on to rocketship firetrucks for me. Everything I've ever done will have been in vain if these don't become a thing!"

Donald Trump: "Vroom vroom, rocketship firetruck!!"
