Hey, who likes science? My brother is doing his thesis speech on quantum entanglement so I made him a little gif to show off the process. This is how he explains it:

Identical supercold atoms, at under 1 nanodegree above absolute zero, smash into each other whilst part of a Bose-Einstein Condensate, a fourth form of matter. These collisions subtly change how the atoms spin, with each atom being left with a quantum memory of the other. This is called entanglement, and if something now happens to one particle, the other particle reacts to it, even if they’re separated by extremely large distances.
