Three lives have I. Gentle enough to soothe the skin. Light enough to caress the sky. Hard enough to crack rocks. What am I?

Why this works

This riddle plays with the three states of water: liquid, gas, and solid. "Gentle enough to soothe the skin" refers to water in its liquid form, like when we bathe or swim. "Light enough to caress the sky" describes water vapor or steam, which rises into the atmosphere. Lastly, "hard enough to crack rocks" points to ice, which can expand in cracks and break apart rocks during freeze-thaw cycles. Each line cleverly represents a different physical state of water, showcasing its versatility!
