<P> Celebratory gunfire (also called aerial firing or happy fire) is the shooting of a firearm into the air in celebration . It is culturally accepted in parts of the Balkans, the Middle East, the Central Asian region of Afghanistan, and the South Asian regions of Pakistan and Northern India . In regions such as Puerto Rico and some areas of the United States it is practiced illegally, especially on holidays like New Year's Eve . </P> <P> Common occasions for celebratory gunfire include New Year's Day as well as the religious holidays Christmas and Eid . The practice may result in random death and injury from stray bullets . Property damage is sometimes another result of celebratory gunfire; shattered windows and damaged roofs are often found after such celebrations . </P> <P> Bullets fired into the air usually fall back with terminal velocities much lower than their muzzle velocity when they leave the barrel of a firearm . Nevertheless, people can be injured, sometimes fatally, when bullets discharged into the air fall back down to the ground . Bullets fired at angles less than vertical are more dangerous, as the bullet maintains its angular ballistic trajectory, is far less likely to engage in tumbling motion, and so travels at speeds much higher than a bullet in free fall . </P>
