523 Hi there, since I watched the movie I'm wondering what the Night Fury fire is made of. The official website says something about "a semi-solid mass, alight with an acetylene-oxygen flame" but:
1. Why does this flame has a such intense indigo colour? Acetylene burns with a yellow, sooty flame if it isn't mixed with enough PURE oxygen (air contains about 20 percent oxygen, and the fireball keeps its colour even during flight)
2. Why does the flame explode on impact and emit a ring of blue mist? Acetylene wouldn't emit blue light in case of an explosion, not even with pure oxygen. The only way I can imagine why that happens, is that the semi-solid mass only CONTAINS acetylene and maybe also a special thickener, which turns it into a non-Newtonic fluid, which means that its semi-solid during flight, but becomes a liquid like water upon striking the target, and the burning fluid gets splashed away in a ring. But where does the destructive shockwave come from then? Acetylene which is dissolved in a fluid (e.g. acetone) doesn't explode/decompose into hydrogen and carbon fast enough to create a shockwave.
Anyone got ideas how the Night Fury fire might work?

Weird. you'd think if they were able to explain what it actually was it would make sense with how it is shown in the film. Anyone else have any ideas?

525 Watched the movie again. The spot where Toothless burns the ground under him to prepare a warm sleeping place clearly shows an acetylene-oxygen flame, all other spots where he breathes fire in blasts definitely show something different. Maybe Night Furies can choose if they want to breathe a flame of pure acetylene, mixed with lots of air to bring in enough oxygen, and use this flame to warm their sleeping place (or maybe attack enemies at close range, which is not shown in the movie, just to not hurt themselves by an explosion), or mix the acetylene with a semi-solid, shear-thinning mass which maybe also contains an explosive component, and fire it with high precison and speed at the target? I could imagine that the semi-solid mass could contain ethanol, acetone or a mix of both. Ethanol burns with a perfectly indigo blue flame, while acetone normally tends to burn with a more yellowish flame, but is much more volatile and flammable. It's also a good solvent for polymers (thickeners) and many explosives. Both acetone and ethanol are good solvents for acetylene, I don't know which is better (but I've read that acetone is used in acetylene flasks to dissolve the acetylene and prevent an explosion-like decomposition, so I think that a mix is possible: Acetone as a solvent and to increase flammability, ethanol for an indigo flame and maybe to destabilize the acetylene and let it explode on impact.)

526 Ugh, I just woke up not to long ago... That made my head hurt. With me though, I don't question things in fiction. It happens because it happens.
