Description
Here is an explosion tutorial as Leth requested, although I don't think I'm so good at explosions that I can teach how to draw them... But I can teach some of the principles behind them!But the best thing to do is really to watch video of explosions. (Some links are supplied in the Flash)
Edit: I just learned that "flame" explosions are officially called BLEVEs (pronounced "blev-ee"), or Boiling Liquid Expanding Vapor Explosions. You can look up this term on youtube to see a bunch of them!
Additionally, a deviant named ~ProfessorDoom has commented about the collapsing of the mystery of gamma ray bursters (pun intended):
"The core of the hypernova collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly the speed of light. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts. In recent years a great deal of observational data on gamma ray bursts significantly increased our understanding of these events, and made clear that the collapse model produces explosions that differ only in detail from more or less ordinary supernovae. Nevertheless, they continue to sometimes be referred to in the literature as hypernovae. The word hypernova itself was coined by S.E. Woosley. [link] " Check the link for more information!

Wait, grenades do that even with the atmosphere. My bad.

In space, the heat of a fire will not rise up because of the lack of gravity. It will just spread out, searching for oxygen. So therefore, the explosion would NOT be red, but instead, blue and spherical. Not gonna happen in a vacuum, though, due to lack of oxygen (for dynamites, regular fireworks, etc.), but pressure from the interior (e.g. grenade) would create either a visible or invisible burst, depending on wavelength, sending shrapnel all over the place.

I learned more about explosions in the few minutes I spent on this than I probably ever will for the rest of my life.

A BLEVE is when pressurized fluid such as steam or refrigerant rapidly escapes its container. The youtube videos are incorrectly labeled.

Awesome! But the colour has to do with the colourtemperature, not so much with the normal colour spectrum. Colourtemperature does not contain green, it is replaced by white. Red, Yellow, White, Cyan, Blue - thats how the colours from the "coldest" to the hottest flames etc. are.

Very cool thing here! And also funny sometimes! It as a pleasure to go through it!

A very good tutorial...very, very good.
Little more info for you...because you seem to be collecting the info
They have determined, as of 2008-2011, that GRBs are caused when a supermassive star detonates, and forces the core into a singularity(black hole) that begins immediately feeding off of the surrounding material. The gravity and rotation of the singularity force the material it's 'feeding' off of into a rotating disk called an accretion disk in which the closer the gasses are to the Event Horizon, the more compressed they become and begin to emit higher and higher levels of radiation until they finally meet the Event Horizon and a small amount of gamma radiation manages exceeds the escape velocity of the black hole and fires off into space as a pair of twin-jets of high energy gas, dust, and lethal radiation along the axes of rotation.
Physicists calculate that GRB 'hypernovae' occur approximately 100 times a day through out the universe, and about once every 10-20 thousand years in the milky way galaxy alone, and the Crab Nebula Supernova Remains are the result of a GRB detonation that occurred approximately one-two thousand years ago and was recorded by the early Chinese(currently this blast stands as the third most powerful and 4th brightest explosion observed in the universe to date).
The exact details of the nature of a GRB are still enigmatic, however.

I don't know how this helps me at all...I'm not even sure how I got here, but I learned a valuable lesson from this.
Wolves tend to cause spontaneous combustion to the air around them.

I like you! We have a lot in common, in fact--at least from what I can ascertain from this artful and enlightening guide. You seem like a rather left-minded fellow, and yet artistically talented. I am in a very similar predicament, in fact.
Anyways, great job. I enjoyed your explosive depictions. ;D

I just wanted to say THANK YOU!!!!
I wanted to draw an explosion in the background for a drawing for my sister and this helped me SO MUCH!!!!

I suck at Physics... but you totally explained it in a way I understand. The flash was pretty clear and gives you the basics to work with, plus explained different types of explosions (which I had no idea existed).

WOW!! this goes into so much information, and most of this i didn't know of till now! thanks for this tutorial, this helps alot, in regard of basics.

thanks for putting this tutorial i was having trouble with the shock waves of an explosion to push clouds. thanks for putting this up.

Awesome tutorial. I just realised I can never draw a realistic explosion, I can barely draw a fake one (actually I kinda can't) but thanks for the lesson.
BTW when fart and fire are mixed they kinda explode is that a chemical reaction?
