Well ive read the thread on here telling us about the 4231 on the coke machines... since then ive been looking for ways to cheat and hack machines to get money and drinks. Unfortunately some of the newer machines have prevented some of these techniques. I will tell you what tricks i use, which ones work and which ones don't just in case you do come upon that special machine :) 1. This is the first thing that ive ever tried that has worked. What you do, get either a bic pen or something the same length of a pen and stick it up between the guard and the lid of the drink machine. This only works on the machines with the guards on them that prevent you from reaching up there. Some machines require two pens on both sides b/c of the force behind the can/bottle, ive always found 2 more effective anyways. Be sure that the pen is in tight and will not let the door open also be sure no one can see it. Come back later and if your lucky FREE SODAS!This isn't really a hack but you still get free sodas! Pictures can be found below. Front view... Side View... 2. The next idea is something im sure most people have heard of. What you do is take some warm water and salt, about 2 liters of water to a 1/2 cup of salt, to the machine your looking to dupe, next take either a newspaper or something that you can fit inside the coin hole acting like a funnel. Then slowly pour into the machine and start pressing away at buttons. If your lucky either soda will start pouring out or sometimes money will come out. If it gets out of control then i would suggest unplugging the machine as soon as you get what you came for.This method i have not tried b/c i don't find it worth messing up the machines in my locker room when i have other techniques. Some machines though have patched this flaw by moving the reader where it cannot be damaged. No images needed for this one, but i did find some articles about this take a look...Products/vending machines saltwater 3. This is for those arcade change machines or those car wash change machines. This method i just found and have done whats needed except put the bill in a machine. Okay here is what you do... either get a 5 dollar bill or a 10 dollar bill and a 1 dollar bill. I would suggest a 5 at first in case you mess up. If you hold up the 5$ bill to the light you will notice a little strip of something that says five and something else on it. Its to the left of Abe down the middle of the U.S. reserve emblem for those of you still looking. Then mark the strip, as where it is located in comparison with the 1 dollar bill, with a pencil or pen. What you need to do is get a sharp knife and some tweezers. Most bills all ready have the place open so just take the knife and open up the pocket a little more to put the tweezers in and grab the strip. If your careful enough the strip will come right out with out breaking. Next line up the strip with the lines on the 1 dollar bill. Tape this down with some clear scotch tape. With a little luck when you stick the bill in it reads the bill as a 5 but really its just a one :). And for those of you thinking you just wasted a perfectly good 5 dollar bill don't worry. Just don't take it to the bank, even though im sure they wont check...instead spend it some where in a store no store will check the 5 for a little strip im sure lol. There ya go... this might be hard work but when you can take 4 5$ bills and 4 1$ bills and make the ones into a roll of quarters its well worth it. The Strip for a little slower people... There are many many other techniques that i may or may not share depending on the response to this thread. Thanks, later.
