So 5 days in the bucket and I measure the Gravity (very simply put, the amount of sugar in a solution) of the beer. By measuring the wort when I pitch yeast and measuring again after a few days I can tell how much sugar is gone therefore how much alcohol is in my beer, and there fore when the Primary Fermentation is finished. I should have taken a picture of my Hydrometer, the tool that measure such things, but I didn't think of it. Any way we measured 1.058 degrees Plato at the start and 1.017 degrees at the end, I was shooting for 1.015 so this was pretty close and gave me about 5.3% ABV. Time to start the secondary fermentation.
See during Primary (read: when most of the alcohol is made) the yeast flocculate and fall out of suspension and make a 1.5 inch thick cake at the bottom of your ferment-er. This is called the "trub," and it can produce some off flavors if you let the beer set atop it too long. So, most brewers run the Secondary Fermentation in a secondary container. In my case a 6 gallon Carboy (one of those bottles you turn upside down on top of a water dispenser.) So I racked it over and it looks like this:

To sanitize I wash my bottles in the dishwasher on hot wash/hot dry, and am ready to bottle the second they come out. So after I get them started I have a few things to do. After the secondary fermentation there isn't much left for the yeast to eat, but I need them to keep working because I want another one of the products they produce. CO2. To get CO2 I have to give them more to eat. I, and most homebrewers, give them Corn Sugar. Why not Table Sugar? Brewers use corn sugar for its non-effect on taste. Table Sugar can leave cider-y tastes in the beer because it is not 100% ferment-able, corn sugar is. So I dump about a cup of corn sugar in the original plastic bucket, which I have cleaned and sanitized, and rack the beer over to it in preparation for bottling. I dump the sugar in first so that the beer mixes while it racks over rather than mixing with a utensil and adding a bunch of oxygen to the mix. Oxygen is bad.

This whole thing just makes me think of Futurama.
