Imagine you're like a tiny toy car, and the wall is made of millions of little blocks that are all glued together. When you try to walk through it, those blocks push back against your legs, just like when you try to push through a big pile of sand! That's why we can't walk through walls like in cartoons.
Examples
- A child tries to walk through a pile of blocks, but the blocks just push back at her.
- A cat walks into a paper wall, only to find it still there.
