    Looking at the photo I see that the AH has leveling screws which allow one to have a large surface area without large quantities of liquid.

    The assistant is hovering over the AH to get it level.

    I can not tell from the photo what liquid is being used.

    Wikipedia tells me summertime high temperatures in Antartica by the coast might be in the +5 to +15 degrees Centigrade. What that means at the pole is a guess but liquid mercury strikes me as not improbable.
