A sprayer is a special tool that helps people spray water, chemicals, or other liquids from a container onto things like plants, bugs, or even dirty stuff. It's kind of like a water gun, but instead of shooting out water, it sprays out a liquid mist. People use sprayers in different ways, like to water plants or to get rid of pests that might be crawling around. They come in all shapes and sizes, from teeny tiny hand-held ones to big machines that farmers use to spray their crops. Almost anything can be sprayed with a sprayer, but it's important to be careful and follow the instructions to make sure it's being used safely and effectively.
