There are celebrations ranging from birthdays to weddings to graduations all year round. Many people release balloons as a form of celebration or memorial, but they don't realize how much damage they can cause to power lines. These thin metallic balloons, otherwise known as Mylar balloons, have a silvery coating that conducts electricity. In the event that they float off and touch a power line, this could result in explosions, fires, power outages, and injuries.
