Madison Checketts, during her leisurely walks along her favourite beach in California, US, was met with a frustrating sight.The once­beautiful shoreline was then packed with wasted plastic water bottles, a cruel reminder of the global plastic pollution crisis.For Madison, who held this beach dear to her heart, seeing it ruined by these non­biodegradable items was deeply upset. The astonishing statistic that Americans cast away 60 million plastic bottles daily, with many of them ultimately ending up in landfills or the vast ocean, was a call to action she couldn't ignore. Driven by a strong sense of responsibility, Madison headed home and immediately set to work on seeking an eco­friendly solution.She named her creative water bottle the Eco­Hero.The magic behind this unique water bottle lies in its material calcium lactate (乳酸钙), a chemical compound.When processed, it undergoes a fascinating transformation from a soft material into a solid, edible shell.This not only makes the Eco­Hero an environmentally friendly option, as it is biodegradable and can break down naturally over time, but also offers a novel and enjoyable experience.The bottle has a delicate sweet flavour, which even gives the water inside a subtle sweet taste. Madison's remarkable invention has rightfully earned her a spot in the final of a renowned US science competition for young people.Beyond the prizes, she has a far­reaching aspiration.She hopes that her Eco­Hero will serve as a motivation, inspiring countless other young students to take steps, no matter how small, towards making the world a more sustainable and beautiful place.
