We can't walk through walls because they're made of tiny building blocks called atoms, and those atoms don’t like to move apart. Imagine your body is full of little balls that are stuck together tightly, when you try to go through a wall, the little balls in the wall push back against yours. It's like trying to squeeze through a crowd of people who all want to stay where they are!
Examples
- Trying to walk through a wall feels like trying to push your hand through a solid block of ice.
- It's like pressing your face into a big, hard blanket that won’t let you go through.
- If walls could feel pain, they’d probably be annoyed when we try to walk through them.
