So I'm working on a story & I was wondering if blood & viscera could extinguish Napalm or Tar.

Like I have superhuman people in mind but I was still wondering if covering yourself completely in human blood & viscera could potentially put out napalm.

I'm envisioning two clashing armies, one much smaller than the other & the smaller army just being lit up by some "napalmish" type substance but charging through the flames & slaughtering the much larger army so fast that the carnage just drowned the "tar".

Tar and napalm are so deadly not because they burn but because they stick to things and burn. Blood is mostly water and could put out fires, but regular water would not be very effective because it flows down pretty quickly. Also napalm and tar are hot, so they would evaporate water quickly. A lot of water would do it but it would be enough that the fire was completely suffocated of oxygen and enough to absorb the thermal energy

They say there’s no such thing as a stupid question... Clearly whoever said that has that has never been to vine...

You could form some idea based in this.

I don't really know how it will fair against high energy combustion, like napalm fire,

but in fiction you can be stretchy with the science to any level of impossibilities.

What you've never imagined yourself in flames & just picking a dude up over your head & ripping him in half, extinguishing the flames with your enemies blood & guts?

Sure I do it all the time

What kind of question is this?
