Scientists have created a moving magnetic slime capable of encircling smaller objects, self-healing and “very large deformation” to squeeze and travel through narrow spaces. The slime, which is controlled by magnets, is also a good electrical conductor and can be used to interconnect electrodes, its creators said. The dark-colored magnetic blob has been compared on social media to Flubber, the eponymous substance in the 1997 sci-fi film, and described as a “magnetic turd” and “amazing and a tiny bit terrifying.” The slime contains magnetic particles so that it can be manipulated to travel, rotate, or form O and C shapes when external magnets
