Essentially what you are doing is creating a culture of beneficial aerobic bacteria. When water sits for a long time without moving, it eventually becomes bacteria ridden or disgusting because harmful bacteria, or Anaerobic (anti-air) bacteria, thrive in an environment lacking oxygen. So when you use the bubblers to oxygenate the water, you are creating an environment that is perfect for the beneficial (aerobic) bacteria thus creating a thriving culture of them. Beneficial bacteria help break down components in the soil that would otherwise be useless to plants.
Two Socks to use as tea bags
Enough worm castings to fill the two socks (1 bag = $10)
Black Strap brand molasses (said to be the best brand)
Air Stones (preferably 4 or more)
Aquarium pumps for the airstones
Standard 5-gallon bucket
Here’s a picture of what a completed setup looks like without water
As you can see, there are four airstones in the bottom. Tying them together can keep them from floating, which is important because they work better on the bottom.
Here is a picture with it connected to the air pumps

Of course it may be overkill, but it helps to create more of the frothy foam that you are looking for. Let it run for 48-72 hours or more. A good amount of foam is a sign that the tea is ready. The more foam the better. It seems that the foam is indicative of there being a large amount of beneficial bacteria present.
So FOAM = READY for use
