Vacuum has been a frequent matter of philosophical debate given that historic Greek periods, but was not studied empirically right up until the 17th century. Evangelista Torricelli produced the 1st laboratory vacuum in 1643, and other experimental methods have been developed as a end result of his theories of atmospheric strain. A torricellian vacuum is developed by filling a tall glass container closed at 1 conclude with mercury and then inverting the container into a bowl to include the mercury.
