What are smudges?

Smudges are like fingerprints that don’t want to be clean.

Imagine you're drawing on a window with your finger, not using crayons or markers, just your finger. When you touch the glass, it leaves a smudge, which is kind of like a blurry line or spot. It’s not clear, and it doesn’t look like a real drawing, but it's still there because your finger made it.

Smudges happen when something, like your finger, a pencil, or even a toy, touches a surface and leaves behind a fuzzy mark. This usually happens if the surface is shiny or wet, like a window or a mirror.

If you try to wipe it away with another finger or a cloth, sometimes it just moves the smudge around instead of making it go away completely.

Smudges can be really fun because they look different every time, sometimes big, sometimes small, and sometimes even wiggly. You can make your own smudge art on windows or mirrors by pressing your finger or hand against them and moving it around like you're drawing with your skin!
