Moving slime – level 3

07-04-2022 15:00

Scientists from the Chinese University of Hong Kong created a magnetic slime that squeezes through narrow spaces, encircles smaller objects, and heals itself.

Magnets control the slime, and it can act as both a solid and a liquid. Scientists envisage that the slime could potentially be useful in the digestive system, such as in reducing the harm from accidentally swallowed objects like batteries.

Scientists move the slime with external magnets. Although the magnetic parts are toxic, they’re safe when they’re covered in a silicone compound. The so-called soft robot can also bend, travel, and reshape to form O and C shapes.

People on social media compared the dark blob to Flubber, the eponymous substance in the 1997 sci-fi film, and they described it as amazing and a bit terrifying.

Difficult words: envisage (to imagine or expect something in the future), silicone compound (a colorless rubber-like substance), eponymous (named after something else).
