So just wondering what you think would be the best thing for making 'stink bombs' out of ..

Criteria:
1)Lasts a long time
2)Has a powerful smell
3)Takes up a small physical space (liquid if possible) ..

Now Butyric acid fills 2 and 3 but it only lasts for like a day max so ..
I'm thinking something I can just chuck in a cupboard/locker etc at school and have it stinking out the place for a month at which point they'll have to do a full search to find it ..

its a bad idea but you are seeking information on how to make it. maybe BLTC mad scientist or laboratory tips? maybe even DIY

Tape a raw dead fish/shrimp/other sea life up to the top of a cupboard, under some stairs, up in one of the roof panels, to the underside of your teacher's/bosses desk.... the possibilities are endless...

This would work well.

Even better would be to do it in several places. Say every 3 or 4 lockers if you can do it.

One time, I got some soldering iron and smoked kippers
Wrapped the kippers against the radiator of his car, they got stuck their and cooked, he couldnt find out what it was, took it back and got it replaced...random story

Horse manure is always pretty pungent, dump it in several places in the room (or natural fertilizers)

It's just a vial of glass filled with stinky liquid.

For everyone else, thanks for the suggestions

Lol these aren't stinky enough though....

Last year on Halloween me and some friends each pitched in for like 10 boxes of those, and split em up and threw them all over school through the course of the day. That shit got pretty stinky, nobody had any idea where the shit was coming from and after a few times, people would learn that it was just easier to start eating lunch outside, cause one of us always ended up fucking up the cafeteria. All in all, good for closed in spaces, but lasts like an hour max...

Make sure you perform the act of stinky on salsbury steak or sloppy joe day.
