You need a Mill File and a glass bottle, any will do, but with beer, it makes the time pass by quicker.
Also, You will need some food too, pizza is the best choice, goes good with making things.
You might want to put in a good movie or some awesome music as well.

Step 2: Start filing.

Picture of Start filing.
Remember, you are working with glass, which can be sharp! Don't cut yourself, Don't be reckless and do this all gloveless like pictured, he almost cut his finger on glass (But in his defense he didn't think it would work...)
Wear a mask too, will protect you from inhaling all those dangerous glass dust bits. :0D
Eye wear would be nice as well, No one wants glass in the eye.

Start off just filing away a bit at a time, gradually turning the bottle as you do so, keep going over the marks you are making, occasionally tap it on the edge of a hard surface, carefully so you don't shatter the glass, Keep this up for about 15 minutes or so, depending upon how much effort you are putting forth and it should just pop off the bottle.

Step 3: Finishing up

After you have gotten the neck off, you will want to smooth out the area where it was cut so you have no sharp edges.

Step 4: Extra step

If you want to go for a slightly more finished look, you can go a step further and file off the lip of the bottle, Mind you the glass is much thicker here so it will take much longer unless you are all fancy and have a dremel tool or a glass cutter, but if you have those, then why would you click on an instructable showing how to make one with simple tools?

Step 5: Finished!

I saw a video of one of my favorite bands "typhoon" recording there album, and they were just using a unaltered glass beer bottle as a slide. Obviously not the easiest for live playing though

You must have small fingers to enter inside the mouth of the bottle =P

Generally plain pound cakes, Not the fancy ones, like birthday cakes. Think more along the lines of "Angel food" cakes.
Basically any kind you would take to a prison.

I have been using the G2 glass bottle cutter with outstanding results.

When I was much younger, we used to cut bottles very easily - we would just tie a string soaked in lighter fluid around the bottle, light it, and, after it burned out, dip the bottle in water. It cracked neat and clean, and all we had to do after was emery the cut edge. We used it to make glasses... water and wine.

I actually stumbled across a video recently on how to do that, thought it seemed very cool, will have to test it out soon!
Awesome, featured.

For the cutting process, finding some way of turning the bottle and holding the file to it would be way easier, actually sticking the file in a clamp and turning the bottle by hand might work well, plus you'd get a smooth cut.
