　　Across the world,humans buy around 1.3 billion single-use plastic bottles a day.However,only about 9% of them are recycled and most of them end up in landfills,the ocean or elsewhere in nature.
　　When beach-loving Madison Checketts noticed that many plastic bottles polluted the sand during her family trip to California,the American girl realized that this needed to be changed.So for her school science project,she decided to focus on reducing plastic litter.
　　During her research,Madison came across a special method of packing water within an eatable material—a gel membrane(凝胶膜).At that time,the girl got her idea:She would design an eatable water bottle called the Eco-Hero.
　　To carry out her idea,Madison developed the method by doing scientific tests with common food additives(添加剂).She also learned from previous research on eatable water bottles.Based on the past research,she improved the method and made her bottles bigger and able to last for a longer time.She found that water,lemon juice and other chemicals could be used together to make a gel bag that wouldn’t break.And the bag could hold up to 3/4 cup of water and could be kept in the fridge for three weeks.
　　“My biggest goal with this project is to help the world,” says the young inventor.She hopes her invention can encourage others to take better care of the planet.“It doesn’t necessarily have to be in a big way,” she adds.“People can make a difference in the world,even if it’s just in a small way.”
