Flask

A clear glass Erlenmeyer flask containing water sits on a white platform, with a vortex of swirling water forming and rotating continuously in the center. The water's surface is disturbed by the spinning motion, creating a visible funnel shape that extends from the top surface down toward the bottom of the flask, with a small object or bubble occasionally rising from the vortex's base. The scene is set in a laboratory environment, with a dark, textured surface visible beneath the platform.
