The left cup is nearly full, the middle cup contains liquid at approximately half capacity with a visible concave meniscus indicating surface tension, and the right cup is completely empty. The clean, minimal style makes it suitable for educational diagrams, children’s science materials, or user interface icons.

Commonly used in elementary science curricula, STEM learning platforms, or health/nutrition guides to explain portion sizes, measurement, or fluid concepts. Matches user intent for visual learning aids, infographics, or instructional content.
