On Wednesday, Hong Kong police used tear gas to disperse protesters surrounding the Legislative Council building, allowing young demonstrators to show off what is now unfortunately becoming an essential skill in the city.

In a video shared on Twitter by journalist Nathan VanderKlippe of Canada’s Globe and Mail, retreating masked protesters are seen immediately surrounding tear gas canisters when they land on the road near them and dousing the canisters with water so that the harmful gas is not released.

In preparation for police use of tear gas, many protesters came prepared to Wednesday’s demonstrations, wearing face masks and goggles with some even wrapping themselves in plastic wrap. Meanwhile, organization was put in place to transport supplies of water bottles and umbrellas to the front lines of the protest.
