On the ISS created a fire jellyfish

The flame has always attracted the attention of a person - as when our ancestors were still warming themselves by the fires in caves, and now, when we warm ourselves by the fireplace, sitting in a comfortable chair (well, or by the fire in the forest, during a hike).

The other day, astronauts on the ISS conducted a series of interesting experiments with fire, which led to the creation of a medus-like education, which was very similar to a living organism.

In general, the current experiment was not the first, earlier astronauts performed literally playing with fire on the ISS, and several times the flame behaved like a living organism, heading towards the maximum oxygen concentration. After such experiments, biologists even had to write that the flame is by no means a living organism, just very similar.

The fact is that the flame in low gravity conditions or its absence breaks up into separate foci, and all this is enveloped in a dim fiery sphere. It looks very impressive. In order to make the experiment even more interesting, astronaut Reid Wiseman used the original system.

The system used two needles, with the help of which heptane and isooctane were mixed. Then all this was set on fire, after which the area of ​​ignition broke up into several separate chambers surrounded by a blue halo. Inside the system began to form additional sources of flame - smoldering soot with temperatures up to 2000 degrees Kelvin.

And the whole system began to move in one direction, while in one of the "poles" a gap formed, which then became similar to the edges of a jellyfish umbrella. In general, it is better to see than to try to present:



Generally speaking, all this was done not for beauty, but for a better understanding of the possible ways of propagation of a fire on the ISS, and thinking through ways to eliminate the fire. Nevertheless, this is probably one of the most spectacular fire-fighting experiments in the entire history of fire fighting.
