Sliding Raindrops Create Electric Power That Can Eat Through Metal!

When rain slides down windows, roofs, and bridges, it actually gathers a tiny electric charge that can make the water corrosive (able to burn or wear away hard objects). Scientists just discovered that this sneaky electric force makes everyday rainwater strong enough to slowly damage metal cars and giant buildings over time. Next time it storms, can you imagine all those little raindrops glowing with invisible electricity?
