Squeeze bottle facts for kids
A squeeze bottle is a special kind of plastic bottle. You can push on it with your hand to make liquids come out. It works because when you squeeze the bottle, the liquid inside gets pushed out through a small opening called a nozzle. This makes it easy to get out things like sauces or glues.

How Squeeze Bottles Work
Squeeze bottles are designed to be flexible. When you press on the bottle, its sides bend inwards. This makes the space inside the bottle smaller.
The liquid inside has nowhere else to go. So, the pressure pushes it out through the nozzle. When you let go, the bottle usually springs back to its original shape. This lets air back in, ready for the next squeeze.
Different Kinds of Squeeze Bottles
You probably see squeeze bottles every day! They are used for many different things.
Everyday Examples
- Sauces: Many of your favorite sauces, like ketchup, mustard, or barbecue sauce, come in squeeze bottles. This helps you put just the right amount on your food.
- Adhesives: Glues and other sticky liquids often come in squeeze bottles. This allows for precise application, so you don't make a mess.
- Wash Bottles: In science labs, students use wash bottles to squirt water or other liquids. They are great for rinsing glassware.
Atomizers
Some squeeze bottles work a little differently. An atomizer is a type of squeeze bottle that sprays a fine mist. Instead of squeezing the liquid directly, you squeeze a part that pushes air. This air then mixes with the liquid to create a spray. Think of perfume bottles or some cleaning sprays.
Why Squeeze Bottles Are Useful
Squeeze bottles are very handy for several reasons:
- Easy to Use: They are simple to operate, even for young children.
- Control: You can control how much liquid comes out. This helps prevent waste.
- Cleanliness: They often have caps that keep the nozzle clean. This also stops spills.
- Portability: They are usually light and easy to carry around.
