Runner's high occurs during moderate to intense aerobics, when natural chemicals called endocannabinoids activate the part of the brain associated with "feeling good."
St. Elmo’s fire is an electrical weather phenomenon occurring when the electric field like those generated by thunderstorms causes the air molecules around an object to produce luminous plasma.
An extremely rare phenomenon, a fire rainbow occurs when the sun's light passes through high-altitude cirrus clouds that have a high content of ice crystals.
