And while we're here, let's go ahead and get these others out for people to read: Bleach+vinegar = chlorine gas, Bleach+ammonia = chloramine, Bleach+rubbing alcohol = chloroform Just don't mix bleach with anything. And while we're at it, don't mix hydrogen peroxide and vinegar, either.

It is a bit sad that so many people miss or forget these important lessons in HS chemistry :P

Wasn't even told that about those things in HS chemistry in my time in my country, not sure why - considered too dangerous knowledge by educators? Only found out about it on 4chan and gasped on how easily we could have accidentally injured ourselves while cleaning our dorm bathroom.

> I was hoping everyone in the US might be able to buy one. This burst of PPE being produced in mass quantities are and were never meant to go in the hands of the general public (i.e., non healthcare workers), though. The general public does not need to be walking around with a full face shield, that’ll be a waste of materials, time and money, unfortunately.

Given that they probably would cost $1 to $5, and take almost no space to store, it wouldn't be a terrible thing for people to have a few if they want them. How many people have a $20 multi-tool that stays in a drawer somewhere? Or some bags of rice "just in case" that end up getting thrown in the trash after being forgotten about in the cabinet for 5 years? It may not be a terrible thing if some percentage of people…

That line of thinking would've made sense a year ago, but the problem now is that "the unexpected happened". Now even things that cost $1-5 to manufacture can't be manufactured fast enough to meet demand (which is probably something like 100 million to 1 billion masks). If we can't get PPE to all of the healthcare workers or even most of them (and right now we can't) then there's no way they should go to the general public.

Why? Most ordinary non-healthcare-worker people have no need for this level of PPE, especially if they're following social distances rules like they should be.

I can't control what other people do in grocery stores. They walk too close and there's nothing I can do about it. I'd like something to keep shit out of my eyes.

Wear sunglasses.

What about the environmental impact of people buying everything "just in case?" Should we be stockpiling oil like crazy right now when prices are low just in case (while also artificially driving up demand)? Isn't one of the key criticisms of farm and manufacturing subsidies that they are wasteful uses of our budget while one of the arguments in favor of them is that it maintains our infrastructure "just in case"? Wh…

Yeah but he said face shield

I’m sad that even though this unique design was done and put online for anyone to print by Prusa, he is hardly mentioned now. On top of that, the design is already commercialized. EDIT: I see now that the design is different, you’re right

There was a community printing effort in Waterloo to make Prusa masks as well, which similarly was evolved for scaling reasons into a design that could be done entirely with laser cutting:

Where they describe how to sterilize it: DO NOT mix those chemicals together (e.g., bleach + rubbing alcohol = chloroform).

interesting, that's a new one I didn't know about. I've always heard the Bleach + Ammonia = Mustard gas, but not that one

If you mix bleach with just about any other cleaning chemical, you get chlorine gas, or chloroform, or some other nasty chlorine-based poisonous fumes.

(though not mustard gas)

So you're saying that four years from now they will have the "updated" design implemented

I was hoping everyone in the US might be able to buy one. Ideally, they'd be cheap enough for municipalities to buy and distribute.

Would just take 6.3 years at current rate of production to make that many.

Unless my math is wrong: 330M/52
