Well that was a frustratingly useless article. They brought in an expert to answer the question and he didn't answer the question. I still don't know what was in the thermos or what to use to extinguish a tear gas canister. This would have been more useful and interesting if PopMech had just bought a few canisters, tested the various theorie, and reported the results.

The article quotes the person from the video who said it was mud.

And the PopMech expert called him a liar.

I can't help but think that there could be an unfortunate inverse to JFK's "Those who make peaceful revolution impossible will make violent revolution inevitable." in this. Tyrants finding their nonlethal weapons not working might more quickly turn to using guns.

If they turn to lethal weapons then political support for them would probably break down very quickly, especially from foreign powers.

As long as commerce keeps flowing, I think China has high enough self esteem that they'll do just fine losing some popularity, and I can't see Western corporations putting any money where their mouths are.

Actually, no corporations have really commented on the matter as far as I know, so they're not even being hypocritical. There is so much money on the line, it would have to get incredibly bloody before anyone would do anything, so I think China has lots of leeway, and I've seen nothing to indicate they're not incredibly sharp.

Earlier quoted context omitted.

Plus, a tear gas canister is just something that is burning slowly, so if you immerse it in something you can extinguish it.

I didn't know that. I always assumed they were just compressed gas with a pinhole poked in them or something.

Naw, it's just smoke from a different source then you'd expect. It's clear if you've been in boot camp. They light up the tabs that produce the gas. Also, gas grenades can get pretty hot, that's why you shouldn't pick them up without gloves.

The failure of teargas to disperse crowds is cited as one of the reasons for quickly bringing the water cannons into service, despite concerns related to using them in the very densely populated streets of HK.

thank whatever or whoever that no one has yet thought of using water cannons with pellets in the water.

Fire needs a flammable source, heat, and oxygen. I suspect the enclosed cannister space hampered the O2 and the mud hampered the combustible material. Mud does seem plausible.

The article says the tear gas cannister uses potassium chlorate (KCIO2) as its oxygen source, rather than atmospheric oxygen, so I'm not sure how effective smothering it would be. The thermos probably is just to protect the protestor's hands.

Based on the other method

No idea why this is downvoted, I think its a daring thesis that China cares what the rest of the world thinks. On top of that there are only a few countries that can afford and are willing to actually act on something like this, there is just to much money to be made in the Chinese market.

That lethal force against protesters leads somehow automatically to breaking down of political support is wishful thinking. Do you really need a list of countries who regularly use lethal force against protesters and are good friends and partners of western governments? When it comes to a state killing protesters all that matters is who the state is.

As for CS gas, it attacks and inflames exposed mucous membranes.

The best homemade solution for protecting lungs is a wet but separated barrier, like being wrapped in wet towels. Oiled rags work decently too and do not need to be moistened repeatedly.

If inhaled, apply amyl acetate inhalant stick to help with breathing.

You will need tight glasses to protect eyes, eg. swimming goggles. Temporarily you can cover them with said wet barrier but that loses you vision and is mostly useful for passing area of gas.

Immersing or tightly covering the source will prevent it from spreading the gas. Careful, it's hot, do not use anything flammable.

Of course a real gas mask with filters or P95 (or better) respirator plus goggles is better for protecting lungs. (N level respirators for dust won't work.)

The inventor of tear gas never meant for it to be used against civilians protesting.

And since chemical weapons are banned for military, I rrad the morbid explanation for research in the area is "no worries, it will not be used in combat, just for crowd control".
