      Absolutely! Ever wondered why the Sun is pretty much spherical? It’s a fire bubble 🙂
      Astronauts at the space station start fires all the time, because it’s very pretty:

      there’s also a neat video explaining why gravity matters for fire:

      Great question, Joef 😀

      Hmm. Sounds potentially terrifying!

      While Scott says the Sun is basically a fire bubble, I think it’s worth noting that the sun isn’t actually on fire 😉

      I don’t know enough about chemistry to be sure, but I think it would be difficult to make a bubble out of something which would burn!
