We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Video of people making crazy crystal balls

I cannot possibly imagine not doing this job in a fully sealed deep diving suit with a hepa filter and chainmail from head to toe.

Silicosis is a fucking nightmare on par with mesothelioma and emphysema.

[–] [email protected] 34 points 1 month ago

Honestly, this is actually one of the times where the satirical word pneumonoultramicroscopicsilicovolcanoconiosis is actually applicable!?

[–] [email protected] 25 points 1 month ago* (last edited 1 month ago)

Yeah, the N95's are a good step, but probably not enough. Some people weren't wearing masks at all.

Also, It didn't look like any of the saws had good safety stops, the angle-grinders were taped down, and the guy cutting the balls seemed to be really close to getting a (gloved) hand sucked into the saw.

Definitely not the worst safety, but people are definitely getting hurt at this job site. And this is what they considered good enough to show on Youtube, so probably worse than we think...

Very cool balls though.

… what's the chainmail protecting against?

[–] [email protected] 10 points 1 month ago* (last edited 1 month ago) (1 children)

Puncturing the diving suit, and also psychological reassurance being near that massive saw.

[–] [email protected] 7 points 1 month ago (2 children)

Chainmail does not secure against punctures, only cuts.

[–] [email protected] 4 points 1 month ago (1 children)

Anecdotal but a kitchen I worked at used it for shucking oysters, i.e. specifically to prevent puncture of skin.

[–] [email protected] 5 points 1 month ago* (last edited 1 month ago) (1 children)

They meant puncture as in stabbing the chainmail with a pointy thing vs cutting it. They do offer some protection but it's easier to get through; more force in a smaller area

[–] [email protected] 3 points 1 month ago (1 children)

That makes sense. I suppose that’s what plate was for?

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago) (1 children)

Yeah it's all about tradeoffs, really. Plate's great but it does weigh and cost more so you wouldn't see as much of it in the field – although it's not nearly as clunky as popularly portrayed because you had to be able to fight in that thing. A lot of the time throwing some mail and a gambeson on a peasant is Good Enough™ for the mass of your army

[–] [email protected] 2 points 1 month ago

I recall a tour guide at the armory museum in Boston describing accounts of (presumably well-to-do) armor wearers showing off their suits’ mobility by doing cartwheels. Still difficult to imagine, but yeah fighting in clunky armor sounds like it could easily be more dangerous than none at all.

[–] [email protected] 2 points 1 month ago

Depends on the mass of the projectile and the size and material of the rings of the mail.

Does volcanic glass really look like that? Perhaps it's just glass slag from a factory.

[–] [email protected] 27 points 1 month ago
[–] [email protected] 3 points 1 month ago

The only type of (natural) volcanic glass found in appreciable quantities is obsidian. I don't know of any others at all.

Thumbnail looks dope, here’s the URL without Google’s shady little tracker if you wanna edit it in:

Edit: this is so cool

[–] [email protected] 11 points 1 month ago (1 children)

Misleading title, but fascinating video nonetheless.

[–] [email protected] 3 points 1 month ago (1 children)

I wasn't sure if this was a community that removes posts if you change the title.

[–] [email protected] 4 points 1 month ago

Understandable, I would have left the original title intact as well. A real enjoyable video, thanks for posting.

[–] [email protected] 11 points 1 month ago

My lungs itched after watching that video.

[–] [email protected] 6 points 1 month ago

A de-gloving injury just waiting to happen.

[–] [email protected] 6 points 1 month ago

Why do we need crystal balls?

Not making a future pun.

[–] [email protected] 4 points 1 month ago (1 children)

Okay NGL, I would love to have blood red gravel to decorate... Something. If I owned property.

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)

Blood red gravel that draws red blood....Doom Guy vibes in landscaping

[–] [email protected] 3 points 1 month ago

... Huh? No, we don't have that, but we do have "oh shit!" as in "Oh shit I lost another finger!"

[–] [email protected] 2 points 1 month ago

Do they have an Etsy?

[–] [email protected] 2 points 1 month ago

There must be easier (and safer) ways to make novelty bowling balls.
