Stirring the solution throughout the reaction is helpful for sharp colour changes, otherwise spatial variations may develop (see Videos).

Use the bottom of an old metal spoon the gently crush the leaf fragments while stirring the solution until you achieve a nice dark green liquid.

Stirring the solution between cyclic voltammetry traces is important as to supply the electrode surface with fresh analyte for each new experiment.

In a hydrodynamic technique flow is achieved at the electrode surface by stirring the solution, pumping the solution, or rotating the electrode as is the case with rotating disk electrodes and rotating ring-disk electrodes.
