What is a vacuum cup and how does it work?
A vacuum cup, also known as a suction cup, is a device that uses air pressure to create a vacuum seal on a surface, allowing it to lift and move objects. It consists of a flexible rubber or silicone cup with a hole in the center, which is connected to a handle or a machine that creates the vacuum. When the cup is pressed onto a surface, the air inside the cup is removed, creating a partial vacuum that causes the cup to stick to the surface.
The vacuum cup works by exploiting the difference in air pressure between the inside and outside of the cup. When the air is removed, the pressure inside the cup decreases, creating an area of low pressure. The surrounding air, which is at a higher pressure, pushes the cup onto the surface, creating a strong seal. This seal is strong enough to lift and move objects, making vacuum cups a versatile tool for a variety of applications, from industrial manufacturing to household use.
