Those little white lines in the sky left behind by jet engines are called contrails or condensation trails.
Those fluffy trails form when the hot exhaust immediately crystalizes into ice in the cold temperatures found tens of thousands of feet in the air.
Conspiracy theorists, however, believe something entirely different. They believe it's a government conspiracy to spray the population and our food supply with chemicals. They call them "chemtrails."

The journal "Environmental Research Letters" recently published a survey polling 77 scientists who study this area of aviation science.
Of the chemists and geochemists surveyed, 76 out of 77 agreed there was no secret government spraying program and contrails were nothing but innocent clouds.
Even though the experts surveyed clearly rejected any atmospheric conspiracy, chemtrail believers are a passionate bunch.
Plus, no one actually knows how many of those "scientists" have been bought off by the government. Wake up, sheeple!
