What IF You Could Walk Through Walls ?

What if you could walk through walls? No more keys. No more locked doors. No more going around buildings. Just take a deep breath and walk straight through. As long as you don't breathe... because the moment you do, you're solid again. Wherever you are. In this animated What If story, we follow the real science of walking through walls: why atoms are almost completely empty and you still can't walk through them, how long a human can really hold their breath, why your brain could forget where your body ends, and why walking through a wall means walking blind. Where would YOU go first? Tell me in the comments. Every power has a price.
