Why is fudge smooth but rock candy crunchy?
Both are sugar crystals, but they are different sizes. Rock candy forms slowly and grows large crystals you can crunch. Fudge makers cool the hot candy mixture and then beat it, which starts millions of tiny crystals that are too small to feel, so it is smooth. The size of the crystals decides the texture. Cooking hot sugar is for grown-ups only.

A Closer Look
Let's take a closer look! Rock candy crunches. Fudge is smooth. Big is crunchy. Tiny is creamy.
Quick Facts
Quick facts! Making the crystals smaller makes candy feel creamier. Slow makes big. Beating makes tiny. Hot sugar is for grown-ups.
Think Like a Scientist
Now, think like a scientist! Put a pinch of coarse sugar on a plate. Put a pinch of powdered sugar beside it. Rub each between your fingers. Which feels smoother? Why do you think so?
Outro
Fudge is smooth and rock candy is crunchy because of crystal size. Rock candy grows big crystals slowly, while beating fudge makes millions of tiny crystals too small to feel. Crystal size changes everything about candy. Remember, only grown-ups should cook hot sugar. Then everyone can enjoy the treat! Science is amazing! The world is full of surprises.
