In microgravity or zero gravity,[seventy four] like an ecosystem in outer Room, convection now not takes place, as well as the flame turns into spherical, with a bent to become more blue and even more productive (although it may perhaps go out Otherwise moved steadily, as the CO2 from combustion does not disperse as easily in microgravity, and has a tendency to smother the flame).
