This is WebWhen making a simple Torricelli barometer, the tube is initially fully filled with the substance (e.g. Mercury). It is then capped off and inverted into a basin containing the same fluid and the cap is taken off. This method actually causes a vacuum to be formed once the barometer's fluid height changes when the atmospheric pressure is sensed.
