A simple formula that could be useful for air purification, space propulsion, and molecular analyses

Google Science Feeds - Mon, 06/17/2019 - 12:41
When a raindrop falls through a thundercloud, it is subject to strong electric fields that pull and tug on the droplet, like a soap bubble in the wind. If the electric field is strong enough, it can cause the droplet to burst apart, creating a fine, electrified mist.
