A recent tweet from @PatriotCoburn says:
Holy Shit the protesters in Hong Kong are grabbing the canisters of tear gas dropping it into liquid nitrogen and turning it into its harmless solid form.
It shows a video of a person in a gas mask and gloves putting a smoking tear gas cannister in a small bottle, shaking it, and emptying the resultant slush on the ground.
The tweet has been retweeted around 20 thousand times, and liked over 55 thousand times and widely shared on blogs and similar.
Does this video show someone disabling a tear gas cannister with liquid nitrogen?
