Half-filled Liquid Cylinder Illustration

A clear, tall cylinder, perhaps a beaker or a glass, is depicted filled precisely halfway with a dark blue liquid. A cluster of small, light-colored bubbles can be seen clinging to the left inner wall of the liquid. The transparent container itself has a subtle, almost ethereal blue aura or outline, suggesting a glow. It's a clean, straightforward graphic representation of a liquid level.
