Where the hell is my cat?
Quantum Entanglement is like when you know exactly where your cat is in the house, but also somehow in the neighbor's house, and also on the moon, and also in a parallel universe.
It's like your cat's position is connected to the position of another particle on the other side of the universe, but only when you're not looking.
When you do look, the cat disappears from all places, but reappears in a different place, and you're left wondering if it ever existed at all.
