Ángela Karime Hernández Venegas, a 17-year-old student at CETIS 78 in Altamira, Tamaulipas, won the gold medal at the ISIF 2026 International Science and Technology Competition in Indonesia with "Vortex Tech", a prototype acoustic extinguisher that uses low-frequency sound waves to put out fires without water or chemicals. The project, created with her uncle José Arturo Hernández Muñoz, beat 110 other entrants at the International Science and Invention Fair in Jakarta.

The prototype uses 30-hertz waves generated by a 12-volt battery connected to an amplifier and a speaker.
The vibrations create vortex rings that displace oxygen and destabilize the flame without chemical agents or water.
So far it can extinguish flames at a distance of 2 meters, and its creators continue to refine the model.
