Figure1: Illustration of the key experimental setup. Several variations of this
setup were also used in the actual experiments as described in the text. For
example, in one variation, the manipulation was heating the water in the 3rd
reservoir to boiling point and then cooling it down. In a second variation, the
gravity measurement was eliminated and the manipulations were first adding
5ml concentrated HCl (30%) to the third reservoir, then adding 20g NaOH to the
same and third heating the same to boiling point. In a third variation, the Dewar
was located more than 500 feet away from the site of measurement. In fourth
variation, the gravity and pH measurements were eliminated and the
temperature measurements were carried out more than 50 miles away from the
location of the Dewar.
