The Spouting Cylinder by United Scientific is a clear acrylic cylinder, 19-5/16" high, with three vertically aligned spouting nozzles spaced 4-3/4" apart. Each nozzle has a stopper so pressure at each depth can be shown alone, and a filler hose barb at the top keeps the water level constant. Physics teachers use it to demonstrate Torricelli's theorem and how water pressure increases with depth.
