Why can't the pneumatic watering can water the watering can?

It may be that the water in the watering can is too full. Be careful to leave some air in it to let the air pressure overflow the water pressure. Be sure to leave some air, and don't fill the water too full.

Introduction:

A watering can refers to a pot filled with water to water flowers. The water spraying part is like a lotus, with many small holes.

Expand:

Air pressure is the atmospheric pressure acting on the unit area, which is equal to the weight of the vertical air column extending upward to the upper limit of the atmosphere. The famous experiment in the Madeborg hemisphere proved its existence. The international system unit of air pressure is Pascal, abbreviated as Pa, and the symbol is PA.

Reasons for formation:

According to the theory of molecular dynamics, the pressure of gas is caused by the frequent collision of a large number of molecules with the container wall. The impact time of a single molecule on the container wall is very short, and the effect is discontinuous, but a large number of molecules frequently collide with the container wall, and the force on the container wall is continuous and uniform. The ratio of this pressure to the wall area of the container is the pressure.
