Mexican student builds sound-based fire extinguisher, wins gold medal at an international science fair
Mexican student Ángela Karime Venegas Hernández won a gold medal at the International Science and Invention Fair for creating a sound-based fire extinguisher. The device uses low-frequency sound waves to create a vortex that displaces oxygen, effectively extinguishing flames without chemicals.
Why it matters
This innovation offers a potential non-destructive alternative for fire suppression, particularly for sensitive electronics.

I like to think the world continues to provide in beautiful ways. Technology, in the right hands, is about finding solutions to real-world problems, and would continue to evolve to refine those solutions--and not create an alternate timeline many of us would prefer to live in.
This was the quest of Ángela Karime Venegas Hernández, a 17-year-old girl living in Tamaulipas, Mexico. As an electronics student at CETis 78, a public technical high school, Hernández set out to discover how to put out fire without water, foam, or powder -- the very properties of a fire extinguisher.
