Man, I hated the execution of the Cavendish experiment. Not only come
in at night *but also* try to time the buildings HVAC system to get a
good run... Arrgh.

If anyone wants to do a real equipment experiment involving gravity,
Tel-Atomic has a version of the Cavendish experiment that uses a
computer to analyze the data. The apparatus cost ~ $2,000. In the
past this experiment often didn't get done due to the weakness of the
force and the sensitivity of the apparatus to vibration. If anyone
wanted to do it when I took advanced lab they had to come in at night.
