About the Communicating Vessels Test Tubes black filled icon

Two round-bottomed test tubes with graduation marks stand side by side, capped by collars and joined both by a horizontal connecting pipe near their middle and by an arched bar overhead, with short stubs projecting left and right.

It illustrates the principle that linked containers settle to the same level, so it works in physics and hydraulics lesson slides, science course catalogs, lab equipment listings, e-learning quiz screens and engineering explainer diagrams.

This is the solid black filled version of the communicating vessels test tubes icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
