Control the Pauli Exclusion Principle. Sometimes I wanna turn it
  off, fall through the chair, bounce back up again.

  I'd have to jump first, so that I land back above ground so I
  can turn it back on quickly enough to land on solid ground
  again.

  Otherwise.. bounce bounce bounce bounce, through the earth and
  back again 'til I reach the middle.

  NOTE: a number of other special powers may be required with the
  package, including NOT DYING and being able to harden some human
  abilities such as PAIN.
