Then, once the 1 1/2 hrs has passed, turn the fuel off to the heat source, and remove the head from the pot once again. BE CAREFUL, the 2 nose bones in the front will have either boiled off, or be loose enough to pull out (I'll cover what to do with this later). Once again, set it on your work station and pick the rest of the stuff off, use a gentle hand if using a knife. The bone has started to soften and can be easily scarred. Go back out to the water balloon filler nozzle and rinse off the skull one more time. Most everything will be completely gone by now. If not, use what ever tools you can muster to get the job done. Remember to go slow, or you WILL ruin all your efforts because you rushed at the end, and it's NOT worth it. The cartilage in the center of the nose will pull right out. Just grab it with your fingers and pull it out. My boys thought that was really cool.
Get all the pieces gathered up. If your lucky, there will be only 1 piece. At most, you will have the skull and the 2 front nose pieces.
Now here is where the VERY understanding wife comes in handy...
