Thanks for the reply. I've been doing well with understanding the implications of the test and the after effects but I struggled with understanding the state of the two particles themselves. Namely, the trouble was with understanding that no one but the people who entangled the particles are actually aware that they are entangled. There is no way for a stranger to look at two particles (given they were entangled by someone else) that those particles are entangled. They'll look like two normal particles. The answers here have helped me understand this.

I think all particles are basically entangled. When you get a photon from the sun it's probability of it being in a given state depends to an extent on the state of all the other photons coming out of the sun. But it's too complicated to figure and so appears random. It's only in simple experiments where exactly two particles are entangled and don't interact with others that you can figure out and notice the effects.
