It's always fun to guess which subversive "ripped from the headlines" DIY Halloween costume will show up at NYC's annual parade. I think on Thursday you're going to see at least a few "Hong Kong Protest" outfits.
What would that entail? Since the actual protestors are improvising gear out of household items, most of the props are things you probably already own, or will find useful enough to buy. Here's our recommended list:
Whether for costume use or actual use, a respirator's no good without the filters. For hipster-level accuracy, go for this pair of 3M's 60626 cartridges, which offer protection from "Organic Vapor, Acid Gas, Ammonia, Methylamine, Formaldehyde." (Those are the closest items we could find to tear gas.)
Regular safety glasses don't offer side protection from pepper spray, so go for these canister-style specs, which seal all around your eyes. (Note that the cheapies in the first image are the costume variety; if you want the real deal for use in your shop, drop $34.95 on the German-made variant that welders use.)
Protestors have been wrapping their arms and bare skin in sandwich wrap, to avoid the irritation caused by pepper spray. With 250 square feet per roll, you'll have enough to wrap yourself and a bucketful of sandwiches.
For covering those tear gas canisters, so that you can pour water into the hole to extinguish them. The IRL protestors have been grabbing these off of the streets for free, but if you do that while marching in NYC's parade, you might catch a beatdown from someone you think is wearing a police costume and who turns out to be an actual cop.
The latest, most innovative tool in the HK protestor's arsenal. The leaf blower is used (as we saw here) to blow tear gas away from the canister long enough for one of your compatriots to cover and douse it.
