You surely remember the T-1000 terminator from the movie Terminator 2: Judgement Day. It was a shapeshifting liquid robot that made for some awesome special effects. Now the real world has something that approaches the T-1000. These robots are quite small (for now), but watching them is awesome. We get to see one liquify itself to escape jail bars and then turns back into a tiny human again when it's free! SciShow gives four minutes to the robots, and then talks about the odd movements of the earth's core.
