why does your skin bubble when it gets severely burnt? And what’s the fluid?

The fluid is usually either blood plasma, which is the stuff that makes up your blood that isn’t a white or red blood cell, or Serum which is the same thing as plasma, but without any of the clotting factor that plasma has.

Some blisters can become filled with blood directly after injuries. They have the sadly boring name “blood blisters.”
