When you're floating around in the International Space Station, you're constantly reminded that you're having a literally out-of-this-world experience. Case in point: this is what it looks like when you light a candle in microgravity~
Because of the lack of gravity, the air's density is the same in all directions, so that means the heat disperses evenly, making the flame all the same color. Wow~
