Medicine dropper is a small device used to measure and dispense liquids, typically medication, in small amounts. It consists of a plastic or glass tube with a narrow tip at one end and a bulb or suction mechanism at the other end. To use a medicine dropper, the user compresses the bulb or suction mechanism to create a vacuum, dips the tip into the liquid medication, and then releases the bulb or suction mechanism to draw the liquid into the dropper. The user can then dispense the medication by gently squeezing the bulb or releasing the suction mechanism. Medicine droppers are commonly used for administering medication to infants and young children or for precise dosing in laboratory or medical settings.
