A vacuum pump is a device for pumping air out of a certain capacity, i.e. to create pressure, below atmospheric. With the help of such a pump and a vacuum chamber, it is possible to conduct interesting and spectacular experiments, for example, to observe how, when pumping air from a can, a marshmallow (marshmallow) or shaving foam begins to increase in volume (swell), because they contain gas. which, at atmospheric pressure, is not capable of exerting internal pressure on the body and it does not swell, unlike vacuum. Also in the vacuum chamber, the water boils at a lower temperature. And also with the help of such a pump, you can pump out the air from the sealed bags with food, which makes it possible to pump out...
