Yet Another air BLOwer: YABLOFree
The application produces a sound that can turn off a candle light. The sound waves increases the air velocity due to the pressure related to the wavelength of the wave. As the speed increases, the boundary of the flame, in which the combustion takes place, is disrupted and eventually the flame turns off. The application allows to set the frequency at which the sound is produced and it also allows to set the amplitude of the wave prouced by the phone. The application has also an explanation section to help the user set the appropriate frequency that would work with their device. The video below in the description shows how the application works. https://www.youtube.com/watch?v=11Bq-YXCzI4
