I'll leave the plant questions to the real experts, but I did want to
share something. If you really want to get an accurate bubble count, do

1) Get out a stopwatch (most wristwatches have one).

2) Right when a bubble goes start the stopwatch and count the next
bubble as bubble #1.

3) Count 10 bubbles stopping the stopwatch on the tenth bubble.

4) Divide the time on the stopwatch by ten.

Now you have cut your inaccuracies due to reaction time, etc. to 1/10th.
If you really want accuracy (read: you're bored), do the same thing but
count 100 bubbles.
