Quantum tea entanglement is a phenomenon where two tea particles become connected in such a way that the state of one particle can be instantaneously affected by the state of the other, even if they are separated by vast distances.
It's not just a fancy way of saying that you can taste the tea you're drinking, but rather a fundamental aspect of quantum mechanics.
But don't worry, it's not like it's going to give you a headache or anything. Unless, of course, you're drinking tea that's been entangled with a particularly grumpy particle.
Disclaimer: Do not try this at home. Or do. We're not really sure what the consequences would be. Actually, we're pretty sure it would be fine. See some experiments! Ask more questions.
