Why does a new baseball glove feel so stiff?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does a new baseball glove feel so stiff?

The Big Idea

A brand-new baseball glove feels super stiff! Players have to break it in. What does that mean?

Stiff Leather

Step one: Stiff Leather. A new glove is made of stiff leather that hasn't yet bent into the shape of a hand. It's hard to close at first.

Breaking In

Step two: Breaking In. Players soften it by catching balls, adding glove oil, and shaping the pocket. This is called breaking in.

Softening

Step three: Softening. As leather fibers stretch and relax, the glove folds around the ball more easily. A well-formed glove closes smoothly and traps the ball.

A Closer Look

Let's take a closer look! Play catch. Add glove oil. Form the pocket. Stretch and relax.

Quick Facts

Quick facts! Leather is a natural material made from animal hide. New gloves are stiff. Oil softens leather. Catching shapes it.

Think Like a Scientist

Now, think like a scientist! Find a new, stiff leather belt. Find an old, soft one. Bend each one gently. Compare how easily they bend. How is this like a glove?

Outro

A new baseball glove is stiff because its leather hasn't bent to a hand's shape yet. Players break it in by catching, oiling, and shaping it, so the fibers relax and the glove closes smoothly around the ball. Science is amazing!
