How to set up the Boyle's Law Apparatus

In the video below, John demonstrates how to refill and set up the Boyle's Law apparatus. The apparatus consists of a reservoir with a Bourdon gauge and a column of gas in a tube. Some of the key features of the Boyle's Law Apparatus include:

The apparatus is free standing
The calibrated Bourdon gauge reads from 0 - 250kPa
The column of gas is mounted behind a safety screen and has clear calibrations to read the volume of the enclosed gas
The reservoir is fitted with a bicycle valve so that a simple bicycle pump can be used to increase the pressure
The liquid in the column is coloured for visibility
The apparatus is supplied with a bicycle pump and adaptor
