| In an enviroment of zero gravity
and no air currents, what shape would a flame take ? Perhaps the shape of
the object being burnt? | |

| Think! for a flame to occur in
space BOTH components of the reaction have to be supplied. These may begin as solid, liquid or gas, Liquids need conversion to gas before reaction, solids can react in solid form. Some solid reactions produce gas others do not. For a rocket you need solids which produce gas when reacted. The shape of a flame will depend on the setup. | |

It'll be a dim spherical flame.  Soupie twist, Ed G.  | |

| Flames always head up - due to
heat rising - what happens to a naked flame in zero gravity? It cannot go
up, there is no up!! | |

| It goes spherically outwards in
all directions from the source of fuel. However, because of this oxygen
cannot get to the centre of the flame by convection, so it can only
diffuse in very slowly, which make the flame burn only very weakly. The
result is a weak blue spherical flame. They tried this over 20 years ago
on the space station Skylab. Soupie twist, Ed G. | |
