The wiki description amounts to: You have a bunch of things that cannot be described properly without describing all of them, and describing them requires lots of scary math.

Well I don't know how it happens (and I seriously doubt I could explain it to you accurately if I did).
What occurs is pretty simple. Once you entangle two particles they become "linked". In the case of quantum "teleportation" this only a matter of information (in all explanations I see they use the "spin" of the particle). When you observe/measure/disturb one of the particles it picks one quantum state to be in at the exact same time the
entangled particle picks the same state.
Now, I feel I have a responsibility, even as a lay person, to explain that this isn't very useful for teleportation:
Imagine you have two locked boxes. Each of them has a random number generator inside. When you turn the key to open them the random number generator picks a value between 1 and 100, then tells the other one to do the same. They're now both stuck like that, displaying a number forever, in this case it is 54.
If the person who owns the other box opens it he'll see 54 but he won't know if it was like that before he opened it or if he was the one that caused it to change. And you don't know either, to find out you both have to communicate through some other method.

Its like a hole punched through space-time. Anything of the right size can pass through.
I wouldn't call it teleportation. The usual term is a short cut.
An understanding of the physics of it (beyond this famous simplification of the concept) would apparently require knowing what a "three-manifold of the nontrivial topology" is.
