What are molds?

Molds are like cooks who make things grow inside a container.

Imagine you have a favorite cupcake tin, that’s like a mold. When you put dough or batter into the tin, it takes on the shape of the tin as it cooks. Molds work in the same way, but instead of cupcakes, they help things like bread, chocolate, and even plastic toys take shape.

Molds are usually made of metal or rubber, and they have little pockets where the material can go inside. When you heat up something like chocolate or plastic, it becomes soft and flows into the mold’s pockets. Once it cools down, it hardens and keeps that shape, just like how your cupcake turns into a perfect round cake when it bakes.

Sometimes, molds are used again and again, just like your favorite cupcake tin. They help things become stronger and nicer-looking, even if they start off messy or soft.
