Is the space capsule salted? Is there saltwater in the floating cabin?

Yes!

As is well known, in the # floating cabin #, even if we cannot swim, we can easily float on the surface of the water without sinking.

This is because the floating liquid in the floating cabin is a supersaturated mineral solution with a density of 1.29g/cm ³, which is much higher than the density of the human body. Therefore, humans can easily float without sinking.

As far as floating fluid is concerned, its proportion in floating cabins or floating therapy is not significant. Those who have read about the origin of floating development know that the addition of floating fluid is only to blur the body's boundaries as much as possible through the high-density and constant temperature liquid, thereby blocking touch.

So, don't take the appearance of floating too miraculous. It's just a high-density liquid. When it comes to efficacy, it still depends on the underlying technical logic, which is to limit environmental stimulation therapy and natural frequency technology. 

It is not difficult to see from the evolution of its name that the transition from the initial "sensory deprivation cabin" to the later "human energy balance cabin" and finally to the "floating cabin" introduced into China was just a result of fate and market demand.

And as I mentioned earlier, in China, floating liquids are usually artificially mixed with various minerals according to scientific ratios (salt, but not the salt we cook at home. 

Here, salt refers to a type of compound in chemistry that combines metal ions or ammonium ions (NH ₄+) with acid ions) or directly extracted from natural high-density mineral water, and then filtered and processed. There is essentially no difference between the two. However, in foreign countries, magnesium sulfate is more commonly used for blending.
