When something disappears, it’s like a magic trick where a toy or object is there one moment and then, poof, it’s gone the next. Imagine drawing a picture on a chalkboard, and then you wipe it away with an eraser. The picture is no longer there, but you remember it was there before. That’s a bit like disappearing.
Think about the sun setting at night. During the day, the sun is bright and shining, but as night comes, it slowly goes away until it’s out of sight. The sun hasn’t really gone away forever; it’s just moved to a place where we can’t see it. That’s another way to think about disappearing.
Consider when you blow bubbles. You see the shiny bubble floating in the air, and then it pops and isn’t there anymore. The bubble disappeared, but you remember how it looked and how it floated. Disappearing is like when something you can see or touch goes away, but you know it was there before, like a fun game of hide and seek.
