A hollow metallic ball 80 mm in diameter is connected to an absolute pressure gauge. Submerging the metal ball in ice water causes pressure to drop, while submerging it in hot water increased the pressure. Utilizing several data points students can calculate the value for absolute zero.
The Superior Jolly Bulb has two scales. The inside scale measures in kPa and the outside scale measures in PSI.
