Some metals sparkle when you bend them because their surfaces get all wiggly and change how light bounces off. Imagine a calm lake, the water reflects the sky like a mirror. But if you throw stones into it, the ripples make the reflection look shimmering and sparkly. When you crumple aluminum foil or a soda can, it’s like throwing pebbles into the lake of metal: light bounces off in all directions, creating that sparkling effect.
Examples
- Bending a piece of metal and noticing how it seems to shimmer when you shine a flashlight on it.
