This is a longer video of the clouds of smart dust particulates, sprayed by jet aircraft daily over Phoenix, Arizona. On cold days, they come down close enough to video. We are breathing these particulates with every breath we take. Children are walking to school on the street next to this property. This is not pollen or regular dust. This smart dust flocks to the light and moves in a coordinated way. See arizonaskywatch.com for related information, and air sample tests showing which metals are being sprayed and their effects on health and the environment.
