Life goal: Mix liquid oxygen and liquid Hydrogen in a 1:2 ratio and light it up....
@freemo How to they react, when mixed up in liquid state like that?
Even without an ignition source, I would be curious to know.
@design_RG I would expect them to be stable, but im not sure. If you pour LOx on asphalt then it will explode if you step on it I hear. So I could be wrong.
@freemo It is a curious thing, really. The liquid qill be really cold, and that might inhibit it from starting a flame immediately when contacting a combustible material like the asphalt. But it's pure oxygen.
I have read a book on rocket fuels, and it was quite interesting. The amount of difficulties they experienced while looking for better ones, most were dangerous substances; poisonous, unstable, nasty things.
Great book, the author is a Chemistry professor and had a dark sense of humour.
@design_RG The auto ignition temperature of a substance has a non-linear relationship to the oxygen concentration. Too much oxygen will prevent ignition just as much as too little normally. But this is dealing with gases and when we talk about solids I dont even know, i only ever work with oxygen as a gas...
@design_RG Here we have coal against oxygen concentration itself, this is probably the most relevant chart I can find.
@freemo Thank you for the graph, quite interesting.
And I was lucky on finding the book I mentioned -- my copy here is somewhere I can't locate (possibly on my dropbox ebooks folders) but... Bing knows.
FULL pdf text of "Ignition!" is here : https://library.sciencemadness.org/library/books/ignition.pdf

@design_RG Now I want to know what the hell a "mach diamond" is!
@design_RG cccoooolllll! Man wave mechanics are everywhere. I love it
@freemo SR-71 in afterburner mode. Can't resist it.

Mach diamond patterns on the exhaust plume.
@design_RG sooo cool, when i have a minute i have to learn the physics behind what causes this. I cant immediately see what the resonant properties would be that would give rise to this
@freemo more pron.
F-16 taking off in Afghanistan. Mach diamond pattern on exhaust.
@design_RG A slightly better illustration, but without the autoignition temp itself. Still useful to get a mental picture though...
