It is not my intention to sound prosaic when I say, I LOVE BACON. Consequently, my love for these little strips of 'cardiovascular disease' have lead me to experiment in the different methods of their preparation. After using both the standard stove-top frying pan, and the the oven to fry or bake (respectively) the bacon, I have grown to prefer the later. Baking bacon produces more controllable, and reproducible results. However, the materials required to perform this slightly more elaborate method of cooking may not always be at hand. This was the case when I thought up of the disposable, alternative I shall describe for you in this instructable.
All you need is heavy duty foil, and of course, bacon.

Step 1: Averaging the Length of Foil to Use

First unroll enough foil to accommodate the number of strips of bacon you want to make. To average this, it is roughly 1.5 inches per strip, then add 2 additional inches for the walls of the pan we shall make later on.

Step 2: Shaping the Foil

The next step is where you'll decide whether or not this disposable alternative is too elaborate or tedious for your liking. This step involves making the ridges in the now flat foil that will elevate the bacon. We want this for two reasons. The first is to prevent the bacon from frying in its own fat. The second is to allow the fat to flow freely to some extent.
In order to create the ridges, place a long, narrow object such as a pencil of uncovered pen (I used a chop-stick), under the foil, about 3 inches away from one end. Then press the foil down, over your tool of choice. This will produce the first ridge.
Repeat this step, leaving about 1/4 to 1/2 inches in between each consecutive ridge. Continue until there is only about 3 inches left on the other end of the foil.

Step 3: Completing the Pan

After the ridges have been made, press the tool of choice, perpendicular into the ridges, proximately 1 inch away from the foils edge. This will crimp the ridges, and will allow you to fold the foil to produce what will become one of the walls of the pan.
Do this for both edges.
Next, fold about an inch of each edge of the foil upwards. Fold and crumple the corners.

Step 4: Bake the Bacon

All that is left to do now, is to lay the bacon perpendicular to the ridges, without overlapping the strips.

With regards to actually baking the bacon, you will have to experiment and see exactly what oven settings you prefer. To give you a head-start, at 350 F, 15-17 minutes will give you chewy bacon, and 22-25 minutes will give you the hard crunchy stuff.
