When you take a bite of a crisp apple, it crunches because the apple is full of tiny air pockets. When you bite down, these pockets burst and make a noise. It’s like popping a bubble! The more air pockets there are, the crunchier the apple feels. Crunch happens when things break in a noisy way.
Examples
- Biting into a fresh apple is like popping bubble wrap.
- A crunchy apple feels like walking on pebbles in your mouth.
- An old, soft apple is like eating wet sand.
