Animated Line Icon of Test Tube with Liquid and Droplet

This animated clip features a clean, two-dimensional line icon of a test tube. The test tube progressively fills with a liquid, indicated by a solid fill, and subtle bubbles animate at its base, suggesting a chemical reaction or analysis process. Simultaneously, a thought bubble appears beside the test tube, containing a simple droplet icon, reinforcing the theme of scientific testing or liquid analysis. The animation cycles smoothly, presenting a clear and concise visual for data representation, scientific concepts, or medical explanations. Its minimalist design and clear motion make it ideal for explainer videos, educational content, or user interface elements requiring a scientific or healthcare-related visual.
