The dark 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 scientists envisage the slime could potentially be useful in the digestive system, for example in reducing the harm from a small swallowed battery.
