Prompt

Source idea used to generate this video.

Scene 1: Evaporation (0:00 – 0:15) Visual Prompt / Action: Macro shot of a sunlit puddle. The sun beams down, heating the water as tiny, animated vapor molecules rise up into the air. Voiceover / Narration: "It all starts with evaporation. When the sun heats up oceans, rivers, and puddles, liquid water turns into an invisible gas called water vapor and rises into the sky." Scene 2: Condensation (0:15 – 0:30) Visual Prompt / Action: Animated time-lapse of vapor molecules floating higher, cooling down, and clustering tightly together to form a soft, fluffy white cloud. Voiceover / Narration: "As that warm vapor rises high into the cooler atmosphere, it cools down and turns back into tiny liquid droplets through condensation, forming clouds." Scene 3: Precipitation (0:30 – 0:45) Visual Prompt / Action: Close-up inside a heavy, dark grey cloud as droplets merge and get too heavy, eventually falling down as raindrops onto a green forest. Voiceover / Narration: "When those droplets get too heavy for the cloud to hold, they fall back down to Earth as rain, snow, or sleet—a process known as precipitation." Scene 4: Collection / Runoff (0:45 – 1:00) Visual Prompt / Action: Water flowing down hills and mountainsides (runoff) to refill rivers, lakes, and oceans, looping back to where it started. Voiceover / Narration: "Finally, the water gathers in rivers and oceans through collection and runoff, ready to start the cycle all over again! Like and subscribe for more science shorts!"

Video narration

Where does a puddle go when it dries, and how does rain come back? Your puddle hasn't vanished. It has changed form and kept moving. Sunlight warms some of its liquid water, turning it into invisible water vapor that rises into the air. That's evaporation: liquid water becoming vapor. As the vapor rises, it meets cooler air and turns into tiny liquid drops. That's condensation, and the drops gather to form clouds. Inside a cloud, drops join and grow, or ice forms. When they're large enough, they fall as rain or snow: precipitation. The water lands, often far away, and flows downhill into streams, rivers, lakes, or oceans. There it gathers, ready to move through the water cycle again. So where did your puddle go? Some became vapor, formed clouds, then fell as rain or snow somewhere else.
