Take the chemicals that make you cry from an onion along with the smelly compounds and stick 'em in a small spray can. Just as good as mace, maybe even better.

"Why do onions make you cry?" [Detly, Jan 29 2005]

how about the juice from the bottom of a garbage can?

I thought this was something to be sprayed on food.

You need garlic spray if you are attacked by a vampire. Mace works just fine for humans. Why would anyone need onion?

Wasabi spray would be as good as pepper spray, except it would wear off quicker. Six more, bakers.

//Take the chemicals that make you cry from an onion//

That would be sulphuric acid.
-- Detly, Jan 29 2005


It isn't when it leaves the onion but when it dissolves in, and mixes with, the fluid in the eyes it forms sulfuric acid.
-- bristolz, Jan 29 2005


Technically true, but walking around with a sulphuric acid spray bottle would be much more fun.
-- Detly, Jan 29 2005


Well, you could have a two chamber bottle, one with the cysteine compound and the other with the enzyme and mix the two at the nozzle. A binary.
-- bristolz, Jan 29 2005


That way, only the nozzle has to be made of glass, and not the entire thing.

[Oniony]! I thought this was going to be one of yours.

I'm all in favor of anti personnel defensive weapons, but this idea just makes me cry....

Granted, I've been drinking and watching good movies, which has that effect on me, but......

A self defense product I can cook with? Better than habanero spray....[+]

Eau d'echalotte?

If this spray would make them cry, could the symptoms-cause-cause effect (like when smiling makes you happy) make the person feel remorse for what they have done?

Onion-free bun.
