About the Communicating Vessels Test Tubes black outline icon

Two upright cylindrical vessels with flat collar rims stand side by side, linked at the top by an arched bridge and across the middle by a straight pipe with valve blocks at each end. The setup illustrates the communicating-vessels principle, hydrostatic pressure and level equalization. Use it in physics lesson slides, science textbook apps, lab equipment catalogs, engineering diagrams and student quiz interfaces.

Strict mirror symmetry makes the pair read as one apparatus: matching rims, matching rounded tube bottoms, and a centered connector that fixes the eye on the shared level line. It pairs with beaker, flask, thermometer and pressure gauge icons. The valve blocks are small, so render at 40 px or larger in teaching material.

This is the black outline version of the communicating vessels test tubes icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
