Experimental Apparatus


Sparing no effort, I built a table similar in design to the one shown in the photographs of Miss Goligher. Cosmetic differences aside, this is a reasonable approximation of the table lifted and tilted by the medium studied by Crawford and should allow for some reasonable comparisons to be made.

An ordinary bathroom scale was used to determine how much the table weighs and how many kilograms it registers when used to lift the table at the edge. Multiplying by the gravitational constant of 9.81 gives the force in Newtons for either lifting or tilting the table.


Weighing the table shows that its mass is 6.44 kilograms. That means a force of about 63.2 Newtons would be needed to lift the table from the floor.


To lift the table directly, as shown here, would take a force of precisely the same magnitude as the weight.  The experiment bore out my calculation.  The scale registers exactly the weight of the table.

In the absence of convenient ectoplasm, I used a cardboard mailing tube because it is light enough to allow the scale to be zeroed before adding the table.


To simply tilt the table, however, requires 28 Newtons, as measured with the scale.  (My calculations indicated that it should take 26 Newtons to tilt the table, but the observed figure is close enough to make me happy with my methods.)

For control purposes, I waited for the table to lift or tilt due to spirit-controlled forces, even going so far as to request that any spirits present make themselves known by lifting the table. Rather sadly, nothing of the sort happened. (Not at all surprising, but still disappointing.) In the absence of an ectoplasm-producing spirit medium, I seem to be unable to reproduce the purported phenomena of the Goligher séances.


A picture was deemed anticlimactic.
