Water is one of the most terrible places to be when you hear thunder and start to see those streaks of lightning. Get out and run immediately, right?
Despite popular belief, water is a terrible conductor of electricity.Pure, distilled water has nothing for electricity to "grasp on to." Distilled water is basic water you'd find in the wild, but boiled down until the liquid becomes devoid of minerals. Water molecules alone don't have a charge of their own, so they can't swap electrons to allow electricity to pass through them.
Then why is a pool the last place you want to be in a lightning storm?Those impurities that are boiled out are the prime examples of perfect conductors, giving water a bad name.
Similarily, the ocean is a great conductor thanks to the salt and ions in the water. Minerals like calcium and magnesium are the impurities that are found en mass in the water that comes out of your kitchen sink.
