In rural Bihar, many children cannot afford good schools, and struggling students are often ignored. Rohit Kumar, a vegetable seller who once struggled in school himself, solved this by turning his rooftop into a free or low-cost classroom. He uses simple experiments and kind methods to help kids truly understand science. Today, over 1,000 students learn on his roof. This benefits the community by giving every child a chance to study with dignity, regardless of their family's income.
