Three Indian sixteen-year-olds won this year's Earth Prize. The award is for eco-challenges. The teenagers made a special powder made from the seeds of the tamarind fruit. Microplastics in water stick to the powder. They are then removed from the water with a magnet. The powder is a simple way to make water safer to drink.

The teenagers were very happy to win the award. They said it was "incredibly special". Microplastics are in our drinking water. The teenagers said their powder is like a magnet for microplastics. The collected plastic is recycled "so it can't return to nature". The powder will protect our planet from microplastic pollution.
