    Hi,
    I'd like to ask, if its possible to shape a fire. Would it be possible on tealight ?
    I dont want complex shapes just simple ones like sphere, cylinder...

    martin1512: What is a tealight? If you want to "shape" fire I suggest you study this first, then you may decide for yourself what is possible:

    The shape of a tealight (or any small candle/match/lighter flame) is driven by buoyancy and convective flow. Take away gravity, and flames become spherical. Of course, once you take away convective flow, you have to control the flow of fuel and oxidizer otherwise the flame will burn out:
