   Science is cool!
   And this thing here even more so.
   I got to take apart an Adiabatic Demagnetisation Refrigerator Cryostat with the wonderful @stdlogicvector , a small cryostat that was used to cool a transition edge sensor to ~40 mK.
   It works by applying a magnetic field to some funny materials, and when removing that field the material cools down below its original temperature, which is 4.2 kelvin in this case.
   The main cooling is done by a huge amount of LN2 and LHe.
