Okay kiddo, have you ever tasted something really yucky and bitter that made you want to spit it out? Well, that yucky taste is intentionally put into some products like cleaning solutions, pesticides, and even some electronic devices to keep us from accidentally eating or drinking them because they could make us very sick or hurt us.
This yucky taste is called bitterant, and it's a chemical that is added to things to discourage us from consuming them. It's kind of like how your parents might put a bad tasting medicine in your mouth so you won't want to take it again. The bitterant is like that bad tasting medicine, but for grown-ups and things that are not safe for us to eat or drink.
So, next time you taste something gross and bitter, remember that it's there to protect you and keep you safe!
