Cinematic Birthday Fire-and-Fountain Scene

First, create a still image in Google Nano Banana depicting the scene below. Then use that image as the visual reference and use the same scene description to generate a video in Kling v2.5 Turbo.

Cinematic, hyper-realistic video with a static camera shot: a cute 9-year-old boy sits on a wooden park bench in a sunny garden. In his right hand, he holds a 1.5-liter plastic Coca-Cola bottle. Dark liquid erupts from the bottle like a geyser or fountain, spraying upward and splashing back down onto the bench.

In his left hand, he holds a large birthday cake with one candle. He blows on the candle, and a sudden, dramatic bright-orange jet of fire bursts horizontally from it like a flamethrower, contrasting with the liquid. Capture the liquid droplets and flames in slow motion. Use dynamic lighting from the sun and fire, cinematic bokeh, 8K detail, photorealism, and sharp focus on the child's concentrated face.
