Do you have a hankering for a smelly prank? Is one of your buddies just asking for you to get even with him? If so, you're in for a treat. Actually, someone else is in for a mighty smelly time. Read on for several different ways to make a stink bomb.

Steps

Method 1 Method 1 of 4:

Egg Stink Bomb

Download Article

1. 1 Get an egg, and a needle.
2. 2 Use the needle (the thinner, the better) to poke a very small hole in the egg. Advertisement
3. 3 Place the egg in a safe, open to the air container (a shoebox with holes punched in it) and let it sit for a couple of weeks. Theoretically, the longer you let it sit, the better, but eventually the egg will dry out, so experiment to see how long to let it sit.
4. 4 Toss the egg. Once you think you've waited long enough, simply throw the egg (it should be intact except for the pinhole, remember!) wherever you want to stink, and enjoy.

Method 2 Method 2 of 4:

Hair Stink Bomb

Download Article

1. 1 Lay a piece of newspaper or notebook paper flat out in front of you.
2. 2 Lay a good-sized amount of animal or human hair into the center of the paper.
3. 3 Cut off the heads of four or five matches. Place the heads of the matches into the hair.
4. 4 Bunch up the paper into a roll or a ball. Make sure not to bunch the paper too much, or else the stink bomb won't burn correctly. Make sure the match tips stay inside the rolled-up paper, too.
5. 5 Tighten the stink bomb with a loose rubber band.
6. 6 Place two more fully-intact matches into the rubber band. They should serve as fuses.
7. 7 Light your stink bomb in the perfect place and get ready for some nasty smells!

Method 3 Method 3 of 4:

Ammonia and Matches

Download Article

1. 1 Cut off the heads of a book of matches using a scissors. Set match heads aside and throw away or otherwise use the rest.
2. 2 Place the match heads in a clean, unused bottle with a cap.
3. 3 Pour about two or three tablespoons of ammonia into the bottle. Cap the bottle and swirl.
4. 4 Wait three to four days before opening the bottle. Once unleashed, the smell will send shivers down spines and nightmares into heads. This stink bomb forms ammonium sulfide, (NH4)2S.

Method 4 Method 4 of 4:

Onions, garlic, cabbage and burnt hair

Download Article

1. 1 Get the primary ingredients. chop up some onions and garlic until they are finely diced. You can use use any kind of onions but green onions or leeks produce the best results as they are the most pungent. Shred up five large leaves of cabbage.
2. 2 Throw into a jar. Get a pint sized clear glass jar with a lid and scoop the ingredients into it.
3. 3 Add the hair. Add a small lock of either human hair or animal hair to the mix. The hair should rest on top of the mix and be intact as a bundle; this makes the next step easier. (Optional) For an even nastier stench, add one match head to the bundle of hair.
4. 4 Close and burn. Close the lid on the jar and then poke two holes in the lid to allow oxygen to flow into the jar (this will make the bundle of hair burn better inside the jar). Next use a magnifying glass to shine a beam through the jar and onto the bundle of hair until it starts to smoke inside the jar. you want to burn as much hair as possible.If you went with the optional in the last step, shine the beam on the match head.
5. 5 Tape and let it sit. Put two pieces of tape over the holes in the lid and let the smoke filled jar sit in direct sunlight and leave it alone;this heats up the ingredients and lets them blend, and permeate everything in the jar. once the smoke inside the jar has settled, take the pieces of tape off the both holes This is to help the ingredients decompose inside the jar.
6. 6 Brace yourself for the test. after about a week, open the jar and take a whiff to see if its stink has blended enough. Only do this outside, NEVER in your house or anywhere else you don't want to badly stink up. Remember, the longer you leave it, the more wicked it's stench will be. A good indicator that it's ready is being able to detect a whiff from a few feet away after two or three weeks.
7. 7 Unleash. Either open or break the jar in the area you want to stink and watch as people rapidly clear away from the obnoxious, haunting, suffocating stench. An alternative way of doing this is instead of using the whole jar, screen the rancid juice from the putrid mix with an old strainer into a small 2 Oz. pump spray bottle (one of those small clear plastic ones used for travel) and spray where you want to stink, just don't get caught and don't get any of this on you otherwise you will be in for a very smelly time.

Tips

• Experiment with your environment. Change it up a bit, time how long you let it sit and how long it stinks afterward, put it in different environments to find the best one... Maybe even use a needle to extract some of the egg and introduce a foul substance to it. Hydrogen Sulfide is the main chemical used in stink bombs. Perhaps you can rot the egg a little, extract some egg, introduce the hydrogen sulfide, and seal it with Epoxy. Thanks Helpful 2 Not Helpful 1

To make a stink bomb at home, all you need is an egg and a needle. First, poke a very small hole in the egg. Then, place it in a container that isn’t airtight, like a shoebox with holes in it. Leave it for at least 2 weeks for the smell to build up in the egg shell. After a few weeks, just throw the egg wherever you want it to stink. Just don’t hang around to smell it! A quicker way to make a stink bomb uses matches and ammonia. Start by cutting off the heads of about 20 matches with scissors. Put the match heads in a clean bottle. Then, pour 2 or 3 tablespoons of ammonia into the bottle and put the cap on. After 3 or 4 days, your stink bomb will be ready. All you need to do is take the cap off the bottle and run.
