wikiHow to Make an Assortment of Stink Bombs

Three Methods:Egg, Milk and VinegarAmmonia and SulfurEgg Whites and Drano

Stink bombs are an awesome prank and you can easily make several different types at home. All of the ingredients are pretty common, so you probably already have them in the house. Stink bombs are not illegal to use, but you should still choose the victims of your prank carefully.

Method 1
Egg, Milk and Vinegar

  1. 1
    Gather your materials. You will need a container with a lid (or an empty soda can), one egg, one tablespoon of milk, one tablespoon of vinegar, a pair of scissors and a zip-lock baggie.[1]
    • You will only need the zip-lock baggie if you’re using a soda can, since that will act as the can’s airtight “lid.”

    Cut the top off of an empty soda can. You need to use a container that you don’t plan to ever use again, so an empty soda can is a quick and easy choice. Carefully cut the top 2 inches of the can off with a sharp pair of scissors.
    • If you have some sort of plastic container with a tight-fitting lid (that you have no other use for), feel free to improvise and use that instead of a soda can.[2]
    • A glass jar (such as a mason jar) with a lid will also work well.[3]

    Break an egg into the can. You can crack the egg fully open and drop the contents inside, or you can make a crack in the egg and toss the whole thing in there, shell and all. It’s going to smell awful either way.
    • You can even drop the whole egg in there without cracking it, but the brewing time for the stink bomb might take a little longer.
    • Any kind of egg will do – white, brown, free range, etc. Whatever type that’s currently in your refrigerator will be perfect.

    Add milk and vinegar to the container. Measure out 1 tablespoon of milk and 1 tablespoon of vinegar and put them both in the container with the egg. Any type of dairy milk will work, but make sure it’s dairy (for instance, almond milk will not work because it’s non-dairy). Use regular white vinegar.[4]
    • If you dropped the whole egg in there and didn’t crack it, you’ll need more vinegar. Pour in enough so that it covers the entire egg.
  5. 5
    Make the container air tight and stash it somewhere warm. If you’re using a soda can, put it in a zip-lock baggie and close it up tight. The baggie should be large enough so that the can fits easily inside and so that you can still set the can upright on a flat surface after you close the baggie. If you are using something else for your container, make sure you put the lid back on tightly.
    • Once you’ve closed the baggie up, put the can in a warm place where it won’t be disturbed.[5]
    • Let the stink brew up for about a week before using the bomb. The longer you wait, the more intense the stench will be.
  6. 6
    Remove the baggie/lid when you’re ready to use the bomb. Don’t unleash the stench be removing the baggie (or lid) until you’ve decided where to put the bomb! This type of bomb works best if you hide it somewhere, such as in a sibling’s bedroom or under the kitchen table.
    • This bomb will have a terrible stench - a combination of rotten eggs and spoiled milk.
    • Be careful not to get any of the mixture on yourself – it smells awful!

Method 2
Ammonia and Sulfur

  1. 1
    Gather your materials. You will need one plastic container, such as a water bottle, with a lid (do not use glass or anything that will break). Additionally you will need ammonia, a pair of scissors and one book of matches.[6]
    • Ammonia is a cleaning solution. Be careful with it.
  2. 2
    Cut the match heads off of all the matches in the book.[7] Using your scissors, carefully cut off the heads (the striking ends) of all of the matches in your matchbook. Toss the wooden sticks and empty matchbook away – you will only need the match heads. Put the match heads inside your plastic bottle.
    • The match heads contain the sulfur you need to create this bomb.
    • You could go out and buy the chemical sulfur in a powdered form, but this is generally hard to find and expensive.
    • Match heads are much easier to find and safer to use.
  3. 3
    Fill the plastic bottle halfway up with ammonia. Pour the ammonia over the match heads that you’ve already placed in the container. Fill up the container about halfway and then tightly screw the lid or cap back onto your container.[8]
    • Once you’ve put the lid on your stink bomb, allow it to sit for about 3-4 days. The chemicals inside will react and brew up the stench.
    • Be careful not to spill the ammonia and be sure to recap it tightly and put it away after you use it.
    • Never mix ammonia with bleach – it will create a highly toxic gas that can be lethal.
  4. 4
    Remove the lid from the container when you’re ready to use the bomb. Don’t take the lid off until you’re ready! Hide the stink bomb near whoever it is you’re pranking (such as in your sibling’s room, under the kitchen table, etc.).
    • This bomb will smell terrible, like rotten eggs.[9]
    • Be careful not to spill any of it on yourself!

Method 3
Egg Whites and Drano

  1. 1
    Gather your materials. You will need an empty glass jar and lid (such as a mason jar), Drano crystals (sodium hydroxide), warm water, 6 egg whites and a spoon. [10]
    • Drano is a cleaning solution, so be careful with it and around it.
  2. 2
    Pour ½ inch of Drano crystals into the glass jar. No need to use any kind of measuring spoon, just eyeball it. After the Drano, pour about 1 inch of warm water into the glass jar.
    • Again, you can just eyeball it – it doesn’t have to be exact.[11]
    • Be sure to recap and put the Drano crystals away safely after you use the product.
  3. 3
    Crack the 6 eggs and separate the whites from the yolks. Crack the eggs one at a time and separate the white from the yolk. Put the whites into a bowl or mug and dispose of the yolks and the egg shells. After you’ve got your 6 egg whites separated, dump them into the glass jar with the Drano and warm water and stir the mixture well with a spoon.[12]
    • If you’ve never separated egg whites from the yolks before, you can always ask a parent to show you how (although you might want to tell them it’s for an omelet, not a stink bomb).
    • Grocery stores sell little cartons of egg whites already separated from the yolks, so you can always buy that and use it, if you want.
  4. 4
    Put the lid back on the jar and hide it in a warm place for 1 week. During that week, the substances inside will brew together to make the stink bomb. Make sure you put the jar somewhere safe during this time so that nobody stumbles upon it.
    • Every couple of days, give the jar a good shake.[13]
  5. 5
    Remove the lid from the jar when you’re ready to use the bomb. Keep the lid on until you know exactly where you want to put it! You can hide it somewhere, such as in a sibling’s bedroom, under the bathroom sink or under the kitchen table, when you’re ready to pull your prank.[14]
    • Be careful not to get any of the mixture on yourself – it smells terrible!
    • Instead of hiding the uncapped jar, you can always dump the contents out wherever you want the bomb to be – but this isn’t really advised, since you might end up being forced by a parent or sibling to clean it yourself.
