Are you thinking about making your own wine or beer? There are lots of quick and simple recipes out there for making wine but many of them suggest you use a balloon as your airlock. While this is very cheap and practical, I have found that many people claim it can leave a "rubbery" taste in your drink.
Commercial airlocks are not expensive by any means, but if you are like me and don't live close to a home brew store, you are on your own. Ebay sellers want ~$2 plus whatever gouged shipping charges they feel like putting on top of that. I have a simple solution for you, you can make your own super cheap one for less than $2 and maybe even free if you have all the stuff lying around!
I list 2 different methods, one is the bare minimum way (~36 cents plus some spare things you probably have lying around) and the other is the recommended way (a little under $2). I only have pictures for the recommended way but the diagram I use can be altered to work for either method.

Step 1: Materials
Bare Minimum way:
- Tape
- Pen
- Plastic tubing
- Jar (clear is best)
- Water
- Something to punch a hole with
Recommended way:
+ Hot glue gun
+ 1 Nylon barb and matching nut (I got this from the hardware store, ~$1.25)
+ Plastic tubing (~ 2 feet, depending on where you will be placing your jar)
+ Jar (clear is still best)
+ Water
+ Drill
- Tape
- Pen
- Plastic tubing
- Jar (clear is best)
- Water
- Something to punch a hole with

+ Jar (clear is still best)
+ Water
+ Drill
Step 2: Methods
This is my illustration, hopefully it is pretty straight forward. I have some detailed instructions below...
1: Cut a hole in a box
Drill a hole in the lid of your fermentation vessel (or punch a hole in it, however you prefer to make holes). Make sure that it is very close in size to your nylon barb (or pen top). If you make the hole too big you risk not being able to make the seal airtight.
2: Put your junk in that box
Place your nylon barb into the hole you made in the fermentation vessel's lid (the barb should be on the external surface). I got a nylon barb from the hardware store for about $1.25. Lock it down by placing some hot glue around the hole and then quickly bolting the barb to your lid with its corresponding nut. If you are not satisfied with the seal, use more hot glue around the cracks where air may escape.
If you are doing the bare minimum method, put the tapered pen piece in the hole (tapered end facing outward) and tape it down like hell. I am assuming duct tape would be the tape of choice for this method.
3: Make her open the... I mean hook up your tubing
Hook up your plastic tubing. I bought mine from the hardware store for 18 cents a foot but I am sure there are plenty of places you can get it (Maybe some aquarium tubing from a pet store? Not pre-used though, that would be unsanitary). Either way, I bought 2 feet of tubing which worked out quite well, you may need more if you are not using a bucket as a fermentation vessel and have to set the jar somewhere farther away. As explained in the step's title, hook up the tubing to your barb (if using a pen tip you may want to using something, like tape, again to make sure your seal is still air tight, this problem is not as prominent in the barb method though).
4: Cut many holes in your jar's lid
Cut a main center hole in the jar's lid that is large enough for your plastic tubing to fit in, the size of this one is not that important. I place a little bit of tape around the rough edges of the hole as to not damage my plastic tubing. Also, poke many smaller holes around the center one to allow CO2 to escape from you airlock jar.
5: Place your tubing below the water level
This is pretty self explanatory, fill your jar about halfway with water and place the tube below the water level so that CO2 can escape from your vessel but will not come back in (due to the water barrier). I found that the closer the tube is to the water level (while still being below it) the quieter the bubbling noise is.

Step 3: Results
There you have it! You now have your own homemade airlock and it cost you less than $2. Be proud of yourself.
Also, I recommend using water or vodka in your airlock, not sanitizer. This is what I found about it on wikipedia.org (the greatest site ever!).
"Many brewers simply fill the liquid chamber with water, which in itself acts as a sufficient barrier to contamination. Others use a sanitizing solution in their airlocks. However, this is generally a bad idea with a small airlock. Sanitizer does not offer much, if any, additional protection, since airborne bacteria or wild yeasts are unlikely to be able to pass through any liquid and become airborne again in sufficient quantity to spoil beer. More importantly, under some circumstances, material from the airlock can be sucked into the fermenter, and even unboiled tap water is better for your wort or must than most sanitizers. As a compromise, some brewers use vodka, which is sanitary but will not contribute any flavor or character to the finished product other than a small amount of alcohol."

Step 4: Discussion
Let me know if you have any improvements, comments, or airlock ideas of your own!
It would be cool if someone did this but had their excess CO2 go to a plant containment vessel to try to boost their plant's growth...just an idea!
Get your drink on.

I'm brewing directly in 32oz bottles, so I took an old wine cork and drilled a 3/8 inch hole in the center and shoved some 3/8 inch tubing in it. Then drilled out the same in the lid of a perrier bottle I had, punched a couple holes in it, filled it with water and called it dandy.
Thanks again!
So no you should really have an airlock that allows carbon dioxide out but prevents stuff getting in.
As brb112988 said, you must vent the bag/barrel a few times a day (like making prison brew) or things can explode. Draw back to this is that air and wild yeasts are let in each time the bag is opened. Which can ruin the taste and alcohol content.
An airlock type device is needed to keep the oxygen out and allow the co2 to escape. yeast without air produces alcohol, with air you'll just make vinegar.

Good point, the suck back could be avoided by placing the airlock jar below the water level of the fermentation vessel (ie. on the floor, but would require longer hosing). However if something goes horribly wrong and your airlock vessel starts to suck back liquid from your fermenter, you could either: Overflow your brew all over the place or
Possibly suck back nutrients into your airlock, which would then definitely become a habitat for bacterial growth.
Also, I did post that a compromise between the water/sanitizer debate is that some people use vodka (because if you buy the good stuff it should be odorless and tasteless) which will not greatly affect the outcome of your brew except make it a little higher in alcohol content.
