A balloon release is a ceremonial event in which a number of hydrogen- or helium-filled balloons are unleashed into the sky. Balloon releases can be done as a prayer ceremony, to create a photo opportunity, to raise awareness of a cause or campaign, or as a competitive long-distance race.
There is considerable opposition to, and legislation against, balloon releases, due to environmental, flight safety, and wildlife conservation issues.
