Why would the wipers come on without being turned on when it rains or the car gets wet?

Many newer cars have automatic windshield wipers. These work with a rain sensor, usually mounted near the rear view mirror. The sensor uses infrared light to sense moisture- droplets scatter light, and the when enough light is scattered, the sensor decides that it's raining. It then signals for the wipers to come on. Dirt can also fool the sensor into turning the wipers on.

They store water when it rains, inside of them

This is extremely strange and may not have anything to do with the rain. There could be a short in the wiring system that is triggered by the atmospheric pressure in the air.

Stonehenge is being weathered by acid rain. Acid rain is pollution that is mixed with the air. When it rains the pollution rains down causing damage over time to structures and plants and animals.

leave the wiper stalk/control set down one stop from off when you switch off the engine, it will then work automatically when it rains and the engine is running
