Two teenagers from Texas have developed a pen-sized device that uses sound waves to remove up to 90% of microplastics from water in a single pass. The device works by generating acoustic vibrations that cause microplastic particles to cluster together, making them easier to separate from water.
Unlike filters that clog or require replacement, this method uses physics instead of chemicals, making it energy-efficient and reusable. The prototype is small, portable, and could be scaled for household, industrial, or emergency use.
Their innovation earned them $50,000 in awards, but its real value lies in its potential. Microplastics are now found in oceans, drinking water, and even the human body — and removing them is one of the biggest environmental challenges of our time.
These teens proved that young minds aren’t just imagining the future — they’re actively cleaning it.
