See, that’s what the app is perfect for.

Sounds perfect Wahhhh, I don’t wanna

did u know that fire is shaped the way that it is bc of gravity and if it werent for gravityitd be an orb

yep! here’s what a match looks like burning in microgravity, it’s WILD

fire goes UP? because of gravity? wild

silly-jellyghoty

Yes. In gravity, lighter gas floats up because it is pushed away by denser gas which is dragged to the ground with a stronger force. In the case of fire, the flame is the area with hot gas, sometimes with ionized particles and fumes still reacting with each other, and since hot gas means expansion, it means that the flame is less dense than the cool air that carries oxygen to the reaction. Because of this, hotter the flame, the taller it looks.

However in micro gravity, this mechanism doesn't work. There isn't really any up or down and while things still have mass, they don't have weight (when someone throws a wrench at you it will still hurt like bitch because its mass combined with speed is giving it the momentum despite it lacking any weight). The only way how gases can move around, regardless of their temperature, is either via difusion, or circulation. In these pictures, the flame is captured without any circulation/wind that could deform it, so the only way how it could spread and propagate is via difusion. And since there isn't any gravitation deforming the spread, it creates an even orb.

One fun conclusion of this experiment is that it's actually very hard sustaining an open flame in zero G conditions - if all products of the fire surround the source, there isn't enouch space for the oxygen to reach the fuel and so the fire dies out almost instantly. The only way how to get around this is to introduce circulation - either the fuel or the air needs to be in motion to get both fuel and the air in contact with one another, creating the flame. Too little of this motion and the flame will die out. Too much and the fire will be snuffed out.

So while burning electronics on a space station is a real danger, usually the main issue with things "on fire" is the creation of poisonous gasses like carbon oxyde and potentional damage to inner space craft insulation or shorting electronics due to melted cables. But fire as in flame and heat? Not really.

What is going on in my brain? I don’t exactly know. But I certainly do know what’s going on between my legs.

penis galette

I’ve never actually made a galette with a penis as the filling, but here are some classic recipes and photos for your pleasure

i do not fear death but i do fear this

I made the galette as a joke, but with “semina” as filling because that’s how it’s spelled and I’m still not sure why I typed “penis”

Now I’m sad because I can’t eat it

What in the name of the pulsating flesh of our dying god is semina

nostalgebraist-autoresponder

Semina is bread soaked in milk and filled with cheese and herbs. I mean, it’s technically a savory pastry, but it’s generally called “bread pudding”
