Ameren Illinois apprentice Zachary Kaiser attempts to free helium balloons from power lines during a training exercise in Belleville, Illinois on Friday, May 3, 2024. Ameren says Mylar balloons get tangled in electric lines and crews have to remove them from the lines. Mylar balloons are also metallic and conduct electricity, resulting in surges and shorts that have the ability to knock out power to customers, start fires and cause significant damage to the electric grid.
