    No. What water is in space isn’t dense enough to allow the propellers to push it.

    My only issue with this video is that he said you could propel it using the rockets from the warheads, but didn’t address manoeuvring at all. Like, how do you orient the rockets to deorbit, and how do you keep that orientation while they’re firing without spinning wildly out of control and winding up with almost no meaningful change in your trajectory?

    I just don’t think this is very practical advice. It could get people killed if they try it for themselves.

    Well obviously no. You took it out of water! According to ChatGPT, once in space it’s a ‘vacuumine’ because you’re navigating the vacuum of space instead of water!

      Thanks for answering the question, now there’s absolutely no reason to watch this neat, clearly comedic video explaining why. You’re a hero.

      This isn’t clickbait, this is a video version of a question posed in Randall Munroe’s book What If?: Scientific Answers to Absurd Questions
