Meet Vick Tan: The Minnesota student who turned a teabag into a low-cost arsenic filter

In a groundbreaking initiative, a student has engineered a teabag designed to extract arsenic from polluted water. This clever pouch incorporates eggshells and magnetic iron oxide, successfully removing over ninety-eight percent of arsenic during rigorous laboratory assessments. Researchers are also investigating possibilities for its reuse and economical manufacturing. This innovation represents a significant leap towards providing accessible and safe drinking water.
