Communicating Vessels Tubes black filled icon

About the Communicating Vessels Tubes black filled icon

Five vertical glass tubes rise from a shared horizontal base pipe mounted on a small pedestal stand: a straight tube, a slanted one, a bulbed one, a tapered one and a wavy one. Because they all connect, the classic demonstration shows liquid settling at the same height regardless of shape, which makes this useful for physics textbook chapters, science lesson slides, hydraulics and fluid pressure diagrams, lab equipment catalogs and educational app modules.

The wide base bar ties the five tubes into one silhouette, and the deliberately varied profiles keep each column distinguishable at a glance. It sits well beside beaker, test tube, funnel and barometer icons from the same science set. Use it at 48 px or larger so the bulged and wavy tube shapes stay readable.

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