While studying properties of ultrasound in various media, Russian scientists from Altai developed an ultrasound hair-drier and a device for fast cleaning of airport runways from fog.
      
      Both inventions are based upon a natural property of ultrasound to make precipitation formation 11 times faster than normal.
      
      During an experiment, researchers paid attention to the ability of ultrasound to dry materials without damaging them and created a new type of a hair-dryer, which creates high-frequency oscillations around hair, thus removing water molecules from them without doing any harm.
      
      The same property of ultrasound resulted in another invention – a device, eliminating fog from airport runways. The device “collects” water dust into drops, causing rain and “cleaning” air from fog.
