35. Poisonous snow:
A trail of condensed water from an aircraft that contain chemicals made to harm humans. The government put the chemicals in jets for various goals such as for-profit solar radiation management, weather modification, mind control, human population control, and biological warfare. Several demonstrations show that the snow falling in the United States does not melt when burnt with a flame and leaves black colored traces, suggesting that the snow burns like plastic, therefore is not natural and contains chemicals.
