LONDON—Those on the front line of the Hong Kong protests wear household goods to protect themselves, like helmets, masks, and cling film.

“When the teargas hits you, especially the later versions of teargas, it gives you bubbles on the skin,” said John (not his real name) who had cling film wrapped around his arm at a rally in west London.
