What Is Quantum Entanglement?

Quantum entanglement is like having two magical coins that are connected. When one coin lands on heads, the other always lands on tails, even if they're miles apart. Scientists don't know exactly why this happens, but it feels like the coins have a special bond.

How It Works

Imagine you and your friend each get a coin from the same magic box. You go to one end of the world, and your friend goes to the other. When you flip your coin, no matter what it shows, your friend’s coin always matches, even if they didn't flip theirs yet.

It's like having two coins that talk secretly through space.
