O_O woke up an realized something: There are no states of
  matter. Everything is varying degrees of foam! The only reason
  we don't see water vapor much when it boils away is the surface
  tension of water is broken. But it's still a loose foam. Gas is
  a really loose foam. Solid things are foam: Think of foam as:
  compressibility. A diamond would be a very hard foam but
  charcoal would be a diamond in a more foamy state.

  Foam is not a weird ''inbetween state of matter''. It *is* what
  matter is. Thoughts?
