Millikan Oil Drop Experiment - A few questions

    Millikan Oil Drop Experiment -- A few questions

    1. The problem statement, all variables and given/known data
    I'm currently doing the millikan oil drop lab; we're using a PASCO Scientific Model 300a (fairly ancient). Specifically, my partner and I are having major problems making any of the droplets in the viewing chamber go back up when switching the top plate to negative/positive.

    We give it a strong squeeze, we see tons of droplets in the chamber, but they all just keep moving down the chamber. We've had two instances of successfully making a drop oscillate, but we suck at experiments and didn't think about the nuances to using a stopwatch in the dark.

    However, the past 3 sessions we've attempted have yielded NO drops that even slow down when charging the plates. What's up with that? I'm desperately looking for pointers here; I didn't think this would be that frustrating.

    Thanks for any help.
