Quantum Entanglement... Tied together races

BOne of the more basic topics within quantum physics is the idea of quantum entanglement.  Though I said this is basic, this is still a very advanced idea that has been theorized by many physicists; however, I believe that this can be described as well as demonstrated into simpler terms.  As almost everyone knows, the world is made up by particles.  In the past century, there has been research that particles work as pairs.  The reason why they work as pairs is because every particles as a spin.  If we relate this spin back to quantum computing, there is spin up and spin down. Spin up is when the particle is align with the magnetic field, and spin down is when the particle is aligned reverse to the field.  However, if we look at normal physics we know that all momentum must be conserved. This includes angular momentum.  So whenever we observe the spins of two quantumlly entangled particles, we notice that one spin is up and the other spin is down.  While this is interesting what is more interesting is when one particle is both spin up and spin down. Though there is a ratio of whether a particle is spin up or spin down. The quantumlly entangles pair will always fulfill one being up and one being down as if they were attached by imaginary strings that sends information faster than the speed of light. Does this mean that there is a chance we can send information faster than the speed of light. Most likely, that is not possible as particle act in very random and unreliable ways. This means that our information is too complex to be sent through quantumlly entangled particles.
