How Does a Liquid Nitrogen Airhorn Work? Liquid nitrogen is -320 deg F (-196 deg C) which is incredibly cold compared to the air around it. Because the temperature difference is so great, the liquid nitrogen immediately 'boils' when it is exposed to air and turns to a vapor.
Can air horns be refilled?
ECOBLAST Air HornA regular air horn has about 70 to 80 blasts from a 12-ounce can - the ECOBLAST gets thousands of blasts over its lifetime. And when the old airhorn runs out of air, you have to throw it away as opposed to the ECOBLAST, which you simply refill with air.
Why do air horns get cold?
