for the sky to catch fire?

Seriously... I'm sure I heard it on the news once but it might have been a dream... I'm not sure...!

In and of itself, no.

Any flammable gasses are not in enough concentration to actually burn. It takes a certain concentration of flammable gas plus a certain concentration of oxygen to support the combustion. Methane, for example, in a confined space will explode (a very rapid burn) when it is between 4% and 19% in concentration. It is most explosive around 9%. Below 4% there is not enough methane to burn. Above 19% in concentration, the methane excludes too much oxygen, so it won't burn. You can't live in it either.

Circumstances have to really be extraordinary for the sky to catch fire, except if you are a science fiction writer.

By the way, Romin - Nitrogen makes up 78% of what you are breathing and it is NOT flammable. Oxygen is about 21% and Argon about 0.93%. Carbon Dioxide and others make up the rest. Do your homework next time.

I DO NT THINK SO !
But here is an experiment that i did : i brought a jar , i sprayed some "Au do toilet " in it and then i threw a match in it and the flames of fire rose up for about 10 centimeters(but Pl dint try this at home kiddo !) you may also spray some spray in the air and then light a match (dint try this at home either)BUT i dint think that the sky (clouds and stuff.....)would catch in fire !!?

If a combustible gas in a high enough concentration was ignited, it might seem that the sky was on fire. This would quickly dissipate however due to gas expansion and reduced concentration levels.

The sky itself no because the dominate gases in the atmosphere are not flammable but something can come into the sky that is already on fire like comets or metorites.

The whole sky wouldn't. Unless the world was ending.

But suppose you had some sort of combustible gas or liquid in the air, then it might ignite for a few second.

Oxygen assists fire (oxidation). Nitrogen is flammable. But it is not concentrated enough to burn in the atmosphere.
