Meet Rachel Brouwer, a brilliant young inventor from Bedford, Nova Scotia, who began her mission to change the world at just 11 years old. She developed a solar-powered water purification system that uses renewable energy to kill harmful bacteria using UV radiation. Her invention includes a smart soybean wax indicator that changes color to show when the water is safe — a breakthrough in affordable water purification technology.
Her innovative work earned her a gold medal at Canada’s national science fair, a top award at the International Science and Engineering Fair, and even led to an asteroid being named after her — an honor reserved for extraordinary contributors to science.
