I'm sure there was a prison thread somewhere, but I don't see it now. Anywho, this is a list of what you should and should not do when incarcerated.
Do not gamble.
Do not get into favors. Example, don't bum a smoke off someone, they will expect 2 cigarettes later.
Do not take things on credit. See example above.
Do not look at anyone for long periods of time.
Do get into confrontations if confronted. Submission is only seen as weakness. Fight.
Do make a shank. Either from scratching your toothbrush on the floor until sharp, or breaking off a piece of a lunch plate, or getting a chunk of glass. You need a shank.
Do read and work out. You're not going to do anything else but rot. Focus your body and mind.
Do have a use. Either as a holder of contraband, or seller, or something. Otherwise your just a piece of meat for nothing, waiting to get fucked.
Don't do drugs, but don't pass up the opportunity to peddle them for something you need.
Multiple ways to make a prison shank
All prison shanks need two things: a sharp point and a handle for grip. You must also have a hiding place for them. Let your mind run wild.
Use toilet paper to make a small fire, hold a styrofoam cup over it. Let it melt into the shape of a cone. Layer more styrofoam over the cone until its nice and thick. Scrape this against the floor until sharp. It will not have an edge to slash with, only to stab.
Prison lunch tray:
Made from Plexiglas, breaking off a piece of this and sharpening it can actually have a good edge to slash with.
Take the toothbrush and hold it over a toilet paper fire, just barely. let the heat and gravity melt it into a cone shape. Sharpen on the ground.
How to make prison wine
Prison wine can be made in your cell toilet or in plastic trash bags. The recipe:
fruit or fruit juice
raisins or tomatoes
yeast or moldy bread
sugar or powder drink mix (lots of either)
Tie off the top of the bag, and triple bag it. Stick a tube or straw inside so the carbon dioxide can release. Hide the bag for a week.
If you use bread instead of yeast (which is more likely) make sure the bread is moldy but not dry. Put it in a sock in order to strain it from the juice.
Average alcohol content is 10% to 14% if done correctly.
