Droplet 2, Charge A:

• [math]\displaystyle{ V }[/math]=-503V
• [math]\displaystyle{ T }[/math]=26°C

[math]\displaystyle{ t_f }[/math] (s)	59.2	60.1	69.9	62.6
[math]\displaystyle{ t_r }[/math] (s)	9.6	9.3	9.3	9.1

Droplet 2, Charge B:

Our first observation for [math]\displaystyle{ t_r }[/math] was very different and we suspect a recording error, so we are discarding it, and I am displaying it below. We only took two falling times because these took much longer than the rising times and we were lazy.

• [math]\displaystyle{ V }[/math]=-504V
• [math]\displaystyle{ T }[/math]=26°C

[math]\displaystyle{ t_f }[/math] (s)	85.0	87.1
[math]\displaystyle{ t_r }[/math] (s)	2.0	1.43	1.53	1.43	1.52	1.51
