Answer 1

Think of the difference between a flashlight and a laser. The light we experience in our everyday lives isn’t that harmful, but if you take light and really focus it and power it up, you get a laser beam that can cut through steel. But it’s still just light. The same light in a pleasant, harmless sunbeam can turn into a deadly laser with enough focus.

Same thing applies to water. It’s all about the amount of energy.
