      At the top there should be very little pressure, as the condensor connected
      to there is open to atmosphere.

      Most of the pressure occurs in the headspace above the pot, due to the
      slight obstruction that the column packing makes. When packing the column
      though, you don't want to do it too tight - it should be loose enough to
      easily breath through for precisely this reason - you don't want a great
      amount of pressure in the system.
