The barometer was rising so we thought it would be a good day for a picnic
A barometer using water,would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water.
Is platinum a base metal or an alloy? What are its uses besides in jewlery? Where is it found generally and geographically? Why is it so dear?
This device is called a barometer. It typically uses a dial or digital face to measure the air pressure by utilizing thin metal cells containing pockets of air.
A portable barometer that uses a small flexible metal box instead of liquid is called an aneroid barometer.

The aneroid barometer was invented by Lucien Vidi, a Frenchman, in 1844. It is a type of barometer that uses a small, flexible metal box called an aneroid cell to measure air pressure.
The kind of barometer you are referring to is a aneroid barometer. It uses a metal chamber (an aneroid cell) which expands or contracts with changes in air pressure. This movement is then converted into a reading of air pressure on a dial.
