How Could You Walk Through Walls?

You can walk through walls if they're made of something as light and flexible as a piece of paper.

Imagine you're holding a big, soft blanket, it's easy to push your hand right through it. Now think of a wall that's like that blanket, but much bigger and thinner. If the wall is made of tiny, stretchy threads, just like the fibers in a sock, then when you walk toward it, those threads can gently move aside, kind of like how water flows around your fingers when you dip them into a pond.

A regular brick wall feels hard because its bricks and cement are all packed tightly together. But if the wall is made of something like air pockets or soft foam, it’s much easier to walk through, just like how you can press your face into a pillow and it gives way.

Most walls are heavy and stiff, so they don’t move easily. But if they were made of something light and bendy, like the wall in your favorite cartoon, then walking through them would be as easy as sliding through a doorway!
