A Tamaulipas teen built a fire extinguisher that puts out flames using sound
The prototype so impressed education officials that the 17-year-old Altamira resident advanced through regional, state and national competitions to qualify for an international student science fair in Indonesia, where she is presenting this week.

A 17-year-old Tamaulipas native, Ángela Karime Venegas Hernández, is representing her country at the International Science and Invention Fair in Indonesia with a unique fire extinguisher prototype. The device, named Vortex Tech, puts out small flames using sound waves instead of traditional water or chemical methods.
Venegas, who spent a year developing Vortex Tech with the help of her uncle, José Arturo Hernández Muñoz, was inspired by a video of a sonic cannon extinguishing a flame using air movement. Her invention comprises a 12-volt battery, a frequency generator set to 30 hertz, an amplifier, a speaker, and a modified bucket to channel the sound output toward a flame.
The sound waves generate swirling rings of air that disrupt the oxygen supply essential for combustion, effectively extinguishing small flames within seconds. The technology, currently in the experimental stage, works best on nearby flames and is not intended to replace conventional extinguishers for large fires.
Venegas advanced through regional, state, and national competitions to qualify for the Indonesian fair. Tamaulipas Education Minister Miguel Ángel Valdez García praised her achievement and pledged support for her and her uncle's participation.
