This is one guaranteed to clear the halls. Hydrogen sulfide smells exactly like rotten eggs, powerful rotten eggs at that. One time I drove my older sister out of her bedroom and the whole house with one of these devices. The formula was used in several other places as well like the school, the theater, the town hall along with a few other places that had to be cleared of people in a hurry.

A Stinkbomb needs two ingredients to be effective, and something to hold the fixings. An effective container is one of the plastic vials that 35mm film comes in. You need a dilute acid like muriatic acid that is dilute hydrochloric acid used to clean masonry that is available in most hardware stores or a mason’s supply store. This can be kept in the vial until ready for use. The other ingredient you will need is iron sulfide. Iron sulfide is pyrite a common mineral also called “Fool’s Gold.” Break the crystals of this mineral up into fairly small fragments for use.

Just before use mix the ingredients together, and place the Stinkbomb in some place where it is not especially visible, and get far away from the results.

A skunk carries his own Stinkbomb around with him; just ask any dog that tangled with one in the middle of the night. The scouting secret weapon is a chemical called butyl selenol a particularly persistent odor producing liquid that is the selenium analogue of butylthiol a compound made by bubbling hydrogen sulfide gas through butyl alcohol. Any of the common alcohols can be converted to their thiol or mercaptan equivalent by bubbling hydrogen sulfide gas through them. This stuff is so potent that your local gas company adds thiols to natural gas so that you will be able to detect a leak. You can also buy them from a chemical supply house, but be very careful or they’ll drive you out of your own house.

Another particularly nasty stink bomb can be made from glacial acetic acid. You can buy this at your local camera shop as it is used as a shortstop in developing film. The smell is practically indescribable assorted smells like a combination of very strong vinegar and vomit. This can be sprinkled around the area that you want to stink up or placed in a small glass jar and thrown. Be careful because the glacial acetic acid can cause some pretty nasty burns.
