Raindrops Carry Hidden Electrical Damage | Science News
Raindrops aren’t just wet—they’re tiny electrical storms that could be secretly sabotaging your car, bridges, and buildings. New research reveals that as droplets roll across surfaces like leaves or plastic, they pick up charge, then unleash microscopic lightning strikes when they hit protective coatings. These invisible discharges corrode materials faster than previously thought—causing damage even after thousands of impacts. Scientists tested this on Teflon, proving charged drops consistently degrade surfaces while neutral ones don’t. The discovery, published in Nature, opens the door to…
