What Causes the ‘Shine’ on a Wet Street?

Imagine a street like a chocolate bar. When it's dry, light bounces off the rough surface, which makes it look dull. But when it gets wet, the water fills in all the tiny bumps and cracks, making the surface smooth like a mirror. Then, the light bounces off in one direction, so it seems to shine brightly, like magic!

Why It Matters

When you walk on a wet street, it feels slippery too, just like chocolate with melted candy! The water helps make everything look brighter and easier to slide on.
