Dilution is like when you mix a smaller amount of something into a bigger amount of something else. It's like when mommy adds a little bit of milkshake mix to a big cup of milk to make it a bit sweeter. Dilution can be used to make something weaker or to spread out its effects. For example, if you have a yummy chocolate sauce that is too strong, you could add some water to it and make it less intense. Dilution can be used with lots of things, like cleaning products, medicine, and food.
