ScienceRaindrops are tiny lightning bolts, and they’re corroding cars, study finds
A study led by researchers at the Max Planck Institute for Polymer Research found that raindrops can become highly charged as they slide across insulating surfaces. Reaching up to 9,000 volts, the drops may electrically puncture protective coatings like sparks jumping a gap, adding a previously overlooked pathway to corrosion.
