Now that everything is on center and evenly distributed, it's time to pop a bubble in your glass.

This will take some practice.  The easiest way to practice is to clog your pipe first.

To clog your pipe, dip it into glass, and dip your glass into water.  The glass will harden on the inside of the pipe and you'll no longer be able to blow through it (this is fixable).  With the pipe clogged, you can see if you're blowing correctly.

To practice blowing into the clogged blow pipe, hold pipe with one hand near the opposite end of where the glass will be gathered, in a way that you'll be able to put your thumb over the end to trap air inside when you need to.  Place the other hand halfway down the pipe to support it (this hand will be used to rotate the pipe while you're blowing).

Have your thumb ready to cover the only hole that air can escape from on the pipe. Blow into that hole with some force, and cover it up with your thumb fast enough to trap air inside (this is the part that needs practice). It might be easiest to place your thumb in your mouth while blowing, and cover the pipe mid-exhale.  To see if you did it correctly, place the end of the pipe with your thumb covering it next to your ear.  While it's next to your ear, let off your thumb.  You should hear an expelling of air from the pipe.  If there's no exhalation of air, you need to keep practicing.

To pop your bubble, follow the same steps as in practice, but this time it's way more important to make sure you're spinning your pipe constantly, or you're bubble is going to be off center and awkward.

While you're thumb is capping the end of the pipe, keep an eye on your gather!  You're bubble is going to show up on the other side soon, and if it blows out too much, you're going to have to start over.  It's better to do less then more, you can always blow more air in later.  When you see the bubble start to form, stop capping the end of the pipe.  That is to say, take your thumb off the end of the pipe as soon as you start to see a bubble.

Congrats, you've popped a bubble!
