The ISS created a fire jellyfish



    The flame has always attracted the attention of a person - both when our ancestors were still warming around the fires in the caves, and now, when we ourselves are warming ourselves by the fireplace, sitting in a comfortable chair (well, or by the fire in the forest, on a camping trip).

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

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

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

    Two needles were used in the system, with which heptane and isooctane were mixed. Then they set it on fire, after which the area of ​​ignition broke up into several separate foci surrounded by a blue halo. Inside the system, additional sources of flame began to form - 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 imagine:



    Generally speaking, all this was carried out not for beauty, but for a better understanding of the possible ways of spreading the fire to the ISS, and thinking out ways to eliminate the fire. Nevertheless, this is probably one of the most spectacular fire experiments in the history of fire fighting.
