[EN VIDÉO] Amazing chemistry experiments: colorful flames fireworks. Its colors that illuminate the sky adorn our eyes.
As the saying goes, above all, don’t try to do the same thing… on your space station! Lighting a candle in space carries risks. However, this is the experience that two astronauts from the Chinese space station have just had. They wanted to show how fire burns in the absence of gravity.
In space, fires are spherical
In such circumstances, fires burn strangely. There are no teardrop shapes as there were on our good old Earth. In space, it is the rule of spherical fires. The reason is weak convection currents, which allow the flame to spread in all directions.
Remember that since the fire that occurred aboard the Mir space station in 1997, instructions in this area for astronauts have been very strict. Combustion experiments are conducted aboard the International Space Station in a dedicated rack. Even if NASA has already conducted experiments “Opens”. But she was on a ship…with no crew!
