The following year, in 1643, he succeeded in becoming a professor of mathematics in Florence. In 1643, he set about atmospheric pressure and found a tool used to measure, the barometer.
In 1643, Torricelli made an experiment that could be said to be quite simple. This experiment was named Torricelli Experiment, which he used a powerful glass tube with a length of approximately 1 meter and one end is closed.
Using a glove facing up and using a funnel, she pours the mercury from the bottle into the tube to the brim. Then, he tries to close the open end of the tube by using his thumb and directly turn it over.

Quickly, he managed to remove the thumb from the end of the tube and put a vertical tube in a vessel filled with mercury.
He immediately observed the mercury surface in the falling tube then stopped at the height of the taxi column inside the 76 cm tube above the mercury surfaces in the vessel. The vacuum chamber is trapped above the mercury pool.
