To be boring, it sounds like their density was lowered significantly to the boint they are lighter than water. It would also allow them to do said flips with less mass drawing them to Earth. The bleeding part is less clear. Obvious Jesus/Stigmata parallels, but they tend to be more or less harmless and stick to the hands. If it were causing the major arteries to burst, starting with the hands and moving up, it would cause blood to escape rapidly and three minutes should be long enough to bleed out with more than one rupture.
