How do zippers work?
Quick Answer
A zipper works when a small slider pulls two rows of teeth together so they lock, or pushes them apart to open. Inside the slider are grooves that guide the teeth into place—like a tiny track that snaps them together.

Story Synopsis
Zippers are everywhere—jackets, backpacks, pajamas—and kids notice them long before they know how they work. This story answers that question with a simple picture: two rows of little teeth and a slider that travels between them. The story explains that the teeth are shaped so they can lock together. When you pull the slider up, grooves inside the slider guide the teeth toward each other and snap them into one strong line. When you pull the slider down, it guides them apart so the zipper opens again. Miluna keeps the tone gentle and playful, helping children feel proud that they can understand “grown-up” tools. It also encourages slow observation: you can watch the teeth join and separate as you move the slider. Curiosity stories build more than knowledge. They nurture attention, patience, and a love of reading—because kids learn that a calm story can answer real questions about the world around them.
