What are syringes?

A syringe is like a tiny straw you can push and pull to move something from one place to another.

Imagine you have a juice box, and you want to pour the juice into a cup. Instead of tipping the box, you could use a straw, that’s kind of what a syringe does, but with more control.

How it works

A syringe has two main parts: a plunger (like a small piston) and a tube attached to it. When you push the plunger in, it moves liquid out of the tube, like when you squeeze juice from a bottle. When you pull the plunger back, it draws liquid into the tube, like when you suck up soda through a straw.

Why we use them

People use syringes to move medicine or other liquids into the body, like when doctors give shots. It’s like using a tiny straw to send a message (the medicine) from one place (a bottle) to another (your arm). No magic, just science you can touch!
