What is an eye dropper and how does it work?
An eye dropper is a small, handheld device used to dispense precise amounts of liquid, typically in the form of drops. It consists of a glass or plastic tube with a rubber bulb at one end and a narrow nozzle at the other. The bulb is squeezed to create suction, drawing liquid into the tube, and then released to dispense the liquid in the form of drops. This simple yet effective design allows for accurate and controlled dispensing of liquids, making it an essential tool in various fields such as medicine, laboratory research, and cosmetics.
The working principle of an eye dropper is based on the concept of suction and pressure. When the rubber bulb is squeezed, it creates a partial vacuum inside the tube, allowing the liquid to flow in. As the bulb is released, the pressure inside the tube increases, forcing the liquid out through the nozzle in the form of drops. The size and number of drops can be controlled by adjusting the amount of pressure applied to the bulb and the size of the nozzle. With practice and patience, one can master the art of using an eye dropper to dispense precise amounts of liquid with ease and accuracy.
