In this supplemental episode, we look at the study of hydraulics related to pulling water up a pipe by Galileo Galilei. This leads us to the development of the mercury barometer by Torricelli and the investigations of atmospheric pressure and vacuums by Blaise Pascal and Florin Perier. This, in turns leads us to the work of von Geuricke and Robert Boyle.
