Ángela Karime Venegas Hernández, a 16-year-old student from CETIS 78 in Altamira, Tamaulipas, invented a device called "Vortex Tech" that extinguishes fires using sound vibrations. Her device uses a 12-volt battery, frequency generator, and speaker to emit 30 pulses per second, pushing oxygen away from flames and extinguishing fires in 5-8 seconds without pollution or residue.
