The way Quantum Entanglement works is actually a bit different from what you described. Essentially, every particle has a spin, a value that isn't necessarily the particle actually spinning the way we know it, but nevertheless is related to the angular momentum of objects (it's a bit weird). When the spin of a particle is measured in any way, it can only be seen to be one of two states, regardless of how the particles are oriented related to the device: spin up or spin down. Which of these values will be measured out is probabilistic, and which will be more likely depends on several factors.

There's a lot of complexity in the details of how it works, and I don't fully understand it myself, but when particles are entangled, they have interacted with each other such that their spins are linked. When one of the entangled particles has its spin measured, the other particle will have its spin return the exact opposite value, assuming the equipment is calibrated exactly the same (with some interesting math involving individual probabilities, but statistically producing the same result if they are different). This result holds true no matter how far you seperate those particles, so long as you can keep them entangled.

There's no known way of knowing which particle is which (without measuring and interacting with them, breaking the entanglement), and no way to know if or when the other entangled particle was measured, so there's no way to actually transmit that information faster than the speed of light, unfortunately. The only thing we do know is if that other particle is measured, it will return the opposite spin as a measurement.

I hope that wasn't too complicated for most people to understand, and I hope my understanding of the phenomenon is accurate enough that the description wasn't too far off. If anything I said was incorrect, please let me know!
