How to (Pass Your Hand Through A Wall Like A Ghost)?

You can pass your hand through a wall like a ghost by learning how to be invisible to the wall, just like how you’re invisible to a blanket when you sneak under it at night.

Imagine the wall is made of tiny, sleepy blocks that don’t want to be touched. When you try to push your hand through them, they get mad and say "No!", which makes you feel resistance, like you're pushing against something solid.

But if you learn how to move quietly and slowly, the wall’s blocks won’t notice you at all. You’re like a quiet sneaker who slides under the blanket without waking anyone up.

How it works

Think of your hand as a soft, sleepy creature that can slip between the gaps in the wall, just like how a cat can squeeze through a tiny door.

If you move fast and loud, the wall’s blocks wake up and block your way. But if you move slow and soft, they stay asleep, and you pass right through, like a ghost!
