Reading the level of the liquid with her eye at an angle above the horizontal water surface
Gently tapping the cylinder to release any air bubbles clinging to the submerged screw
Choosing a measuring cylinder with a much wider diameter and larger scale divisions
Tilting the measuring cylinder slightly while reading the scale
