This shot captures the moment cream enters the coffee, setting off a captivating display of fluid physics. As the denser cream drop hits the coffee, it creates a gentle shock wave across the surface, followed by a delicate droplet that splashes upwards. Beneath the surface, the cream spreads in graceful tendrils, showcasing diffusion as it mixes with the lighter coffee. The swirling patterns reveal the beauty of density differences and fluid mixing in action—simple ingredients transformed into an intricate flow.
