Spouting Cylinder: Torricelli's Theorem Chemical Bonding Argon is the third mostVisualize fluid pressure and energy conservation Investigate two core fluid dynamics ideas with one clear, classroom ready apparatus. The Spouting Cylinder lets students explore Torricellis theorem qualitatively while also connecting observations to Bernoullis equation and conservation of energy. As water exits from three evenly spaced nozzles at different heights, students see how pressure depends on depthand how fluids obey the same energy laws as
