  The second phase of the experiment was a success. After the bottle cooled (sealed) for about an hour (till it was at room temperature), I stuck it back into the microwave. Within 50 seconds there were small bubbles, and within 56 seconds there was a roaring boiling. Wow... compared to the 1:24 of the standard air pressure (101 kPa), :56 is a great time.
This is especially true when you consider that there was 6 ounces of water and 26 ounces of air in the container. In theory, the more water we have, the more substantial difference in times there will be. I need to double check the first time (unsealed bottle in microwave). I will do that just as soon as the bottle and water cool down. I didn't time it specifically, but I seem to remember that I started with 3 minutes, and ended with 1:36.
I will let you know as soon as I reconduct the experiment.
Wow...
I am so excited. I can't believe this theory actually works in practice. What is better is that the 6 ounces of water and 26 ounces of air means that the times can only get better, the fuller the machine is. Wow... -Ben Salinas EDIT: I reheated the unsealed bottle, and it was almost down to the second: 1:24!
