2C50.40 - Paraboloids and Vortices
Fill the cylinder with colored water to a depth of 4 or 5 cm. Start the apparatus rotating and then watch the parabola that forms at various rotation rates. NOTE: The speed control for the motor is real sensitive so be careful or you will rotate the cylinder too fast and the water will spill out.
