The Effect of Cooling Down a Superconductor

electrons are both negatively charged, right? And so they don't like to hang out with each other. But when you cool down a superconductor, suddenly it becomes possible and even preferable for them to pair up. So can you describe the effect here? Like, why do they pair up and how that helps them flow through the material? Mm hmm. The reason they pair up is that they essentially they deform the lattice in the same way.
