Every omnidisciplinarian mad scientist needs a lab.
…
(I was told I need to reblog things to not be mistaken for a bot, so that’s what this is; if I think about it or if I want to interact with it, it ends up here. I really don’t have the organizational chops to curate an actual blog.)
This rock I found on the beach screams when in water...
Edit: You may have to turn up the sound to hear it. For some reason specifically here on Tumblr it's very faint when I use my computer, on my phone it's fine. When I uploaded it to other sites it was fine either way, but here it's being picky, and I'm sorry. I've tried to fix it by reuploading it, but the results were the same.
Looks like there’s a bunch of very tiny bubbles escaping and making that foam.
Is that water hot? It looks like you are washing the rocks (presumably for use in a project that requires good glue/mortar adhesion or just to make them look nice), so if the water is hot, that heat may be causing gases inside the rock to gradually expand as the rock heats up, exceed the volume of whatever crack or bubble is in there, and escape out some pinhole or hairline fracture.
I would hazard to guess the reason the sound only happens in water is either because the slow leak can push the thin film of water that clings to the rock when out of water out of the way and keep it out of the way, but when it is submerged, the water can push back in and cause a buildup of pressure until the gas can overcome the opposing force and release a tiny bubble before the water closes back over the outlet, resulting in a high frequency periodic motion of the water … aka, a vibration, which then transfers to the air. The metal pan/pot may also be helping this transference by acting a bit like a tuning fork, because sound doesn’t transfer very well from water to air.
If you get a chance, sun-dry the rock for a day, then put it in an oven at the lowest temperature you can get your oven to go (200-250°F/ 95-120°C or thereabouts) for as long as you have patience for, then let it cool in the oven overnight, then put it in the same pan/pot but with cold water… then try a plastic 5-gallon / 20L bucket of hot water, and then a bathtub of hot water.
(DO NOT BAKE AT HIGH TEMPERATURES, THE ROCK MIGHT EXPLODE)
If it doesn’t scream at all in cold water, is quieter in the bucket, and quieter still in the bathtub, then I’d be pretty confident with my guess, because cold water wouldn’t make the trapped gasses expand, a plastic bucket might not transfer sound as well as a metal pot, and a bathtub has a lot more water and is probably more firmly anchored and shouldn’t transfer sound hardly at all.
If making the rock explode sounds fun, don’t do it in an oven, the shrapnel might break the oven window and you’ll definitely end up with rock dust in your oven, which probably isn’t good.
The safest way I can think of is to use a bonfire, and to protect yourself by standing, like, 100 feet / 30 meters away. And wear safety glasses.

A cartoon from 1914 that could have been written today
Proof that after hundreds of years of capitalism, the only thing that's "changed" is the name attached to the foot inside the boot firmly placed on the necks of the poor.
Dear science side of tumblr,
Would it be possible to design a trebuchet that throws a spear
If so how well would it work in reality and would it be possible to throw a spear hard enough to go through 2 ft of concrete (as an example of a target)
Ok so… a trebuchet? Technically possible, it would probably work a bit like a giant atl-atl.
Practical? Nope. What you’re looking for is a Ballista. They look a bit like crossbows, but the arms don’t bend, they’re stuck through a couple of really fat ropes, and the ropes twist as the arms are pulled back.
End result is the same as a crossbow, tho… just a bigger “arrow” that can be anywhere between the size of a small spear to a small, pointy LOG.
Two feet of solid concrete probably won’t be penetrated by a single hit from a ballista bolt, but they can shoot stone balls, too. You could bust down that concrete with repeated direct hits from stone balls about the size of a bowling ball and several times heavier.
If you want a single projectile to punch through two feet of concrete, you’re going to have to start thinking about gunpowder and armor-piercing ballistics. Two feet is a LOT of concrete to get through in one shot by MODERN standards, let alone with medieval tech.
Want to know my spiciest d&d take as someone who introduces a lot of people to the game?
Classes (and subclasses) should be rated for complexity, and newer players should be steered away from overly complex options so that they're not asked to do double or triple the work of memorization of other players. This is especially true if the player is going to be slower to pick up on game mechanics, be they young, old, or simply not someone who's very experienced with games in general.
Think about it this way: everyone at the table is expected to learn the base game (what dice to roll, how to pilot their character by talking, actions in combat), some of which is written down but the rest being vibes based and mostly communicated through gentle coaching by the DM. On top of that a portion of your players are going to have to learn how spells work, effectively doubling or trippling their early game class features. This is to say nothing of druids, who not only have to learn all the base features and spells but also have to keep several different statblocks on hand when it comes time to turn into animals/summon familiars. If you have my luck, it's always going to be the shyest/most anxious player at the table who selects the most complicated class, paradoxically meaning the player who's least likely to ask for help is usually in most need of it.
I'm not saying we should restrict all new players to only playing vanilla human champion fighters, but I think a level of oversight is absolutely necessary when guiding new folks into the game. Consider running a trial adventure that's limited to martial classes, introducing a few magic items half way through to give them a taste of what spellcasting could be like.
Forget about the traditional Tank/dps/expert/support/caster party balance, that shit is for experienced players who know what they're doing.
And don’t forget casters being played by people who get choice paralysis
I must not mock Gen Alpha. Mocking Gen Alpha is the mind killer. Mocking Gen Alpha is the little-death that brings total generational solidarity obliteration. I will engage with Gen Alpha lovingly. I will permit them to be cringe. And when they grow up I will turn my eye to their accomplishments. Where mocking has gone there will be nothing. Only generational solidarity remains
So, there's a lot of USians around who are very clearly fucking fed up with their political choices this election cycle, and planning to sit it out.
And I get it! What's the point of voting if there's no one to vote for?
The thing is, I'm Australian. In Australia, voting is compulsory. We don't get to sit out our elections, and I'll be real honest with you - we don't exactly get better choices than you lot. So how do you vote if there's no one to vote for? You find someone to vote against. And there's always someone to vote against.
Now, we have the pleasure of preferential voting in Australia - We get to rank every candidate from 1 to X, and I'll tell you, there's something so cathartic about putting the biggest bastard of the lot at the very bottom of your preferences. I understand that USians don't get that option - you get to mark one person, and that's it.
That means that you get one shot, so aim it at the biggest bastard of the lot. The candidate you most utterly detest. Put your vote in the worst possible place for them. Don't even think about who that vote's going towards, that's not the point. Remember, every vote is a vote against someone. Make sure you fuck up that someone's election day!
Y'all, the world is sleeping on what NASA just pulled off with Voyager 1
The probe has been sending gibberish science data back to Earth, and scientists feared it was just the probe finally dying. You know, after working for 50 GODDAMN YEARS and LEAVING THE GODDAMN SOLAR SYSTEM and STILL CHURNING OUT GODDAMN DATA.
So they analyzed the gibberish and realized that in it was a total readout of EVERYTHING ON THE PROBE. Data, the programming, hardware specs and status, everything. They realized that one of the chips was malfunctioning.
So what do you do when your probe is 22 Billion km away and needs a fix? Why, you just REPROGRAM THAT ENTIRE GODDAMN THING. Told it to avoid the bad chip, store the data elsewhere.
Sent the new code on April 18th. Got a response on April 20th - yeah, it's so far away that it took that long just to transmit.
And the probe is working again.
From a programmer's perspective, that may be the most fucking impressive thing I have ever heard.
an article on the subject for the curious:
"We're pretty much seeing everything we had hoped for, and that's always good news.”
hoLY SHIT
god I would be UNSTOPPABLE if I was capable of consistently initiating tasks. just you wait. you'll be waiting a while but just you wait
Jeff Bezos's Amazon and Elon Musk's SpaceX are both fighting in court to have the National Labor Relations Board declared unconstitutional. Starbuck's and Trader Joe's joined them in separate lawsuits. All of these companies have a disgraceful history of worker abuse and union busting. All of them have been charged by the NLRB with hundreds of violations of workers’ organizing rights The NLRB is standing up to their union busting. That’s why they’re trying to destroy the NLRB. I'm going to do my best to keep you all informed about this case as it snakes its way through the courts. The future of unions may depend on the final verdict. http://dlvr.it/T49LM1
Well.
If they succeed, that just means we have one less option between where we are now and where we were when we first started making unions.
You know.
Killing the boss. And gunfighting the Pinkertons. And having full scale military engagements with the Army.
You know I used to think "tumblr's absolute refusal to actually engage with the Trolley Problem in favor of insisting that there must be a third, morally pure option that doesn't require them to make a hard decision and anyone who asks them to make a binary choice is just a short-sighted idiot is really fucking annoying, but I guess it's not actually doing any harm".
Anyway that was before we asked tumblr at large to decide between "guy aiding a genocide but making progress elsewhere" and "guy who would actively and enthusiastically participate in a genocide and would also make everything else much, much worse for everyone elsewhere" and the response was that there must be a third, morally pure option that doesn't require them to make a hard decision and that anyone who asks them to make a binary choice is a short-sighted idiot.
The trouble with trying to talk about "the players just dick around while the GM does all the actual work of making the game happen" as a dysfunctional mode of play in tabletop roleplaying spaces is that it's so normalised that a lot of GMs genuinely don't realise that's what's happening. They'll look at a description of the problem and with a perfectly straight face declare "yeah, that shit would never fly in my group, that's why we [proceeds to describe a way of organising play in which the GM does all the actual work of making the game happen]". And we wonder by GM burnout is such a universal phenomenon!
(It's by no means limited to structured or rules-heavy play, either. Semi-freeform play where you throw out 90% of the rules and look to the GM for an off-the-cuff ruling every single time someone picks up the dice is one of the principal forms of making the GM do all the actual work.)

I’m a player at a table populated by 6 players total and a DM…
ALL of which have RAMPANT ADHD
And only two of us, myself included, are medicated for it (because America doesn’t do free healthcare but we do have free global unhealthcare, make it make sense)
And I’m the only one who is properly medicated for it, the other person is currently trying to find a medicine that doesn’t trash their emotional stability or their sleep schedule… so far without much luck.
I play a barbarian with oddly high mental scores because we rerolled 1’s when rolling stats because this is almost everyone’s first game ever
He’s also the only main front liner and the only tank that isn’t also our only healer
So he’s become more or less the battle strategist and the cat-herder by virtue of being decisive and straightforward. If we get bogged down with planning a fight or deciding if we should do a side quest or how to handle a situation, I will have my character start saying stuff like “c’mon we gotta come to a decision here soon, if no one else is going to agree to anyone else’s plan, I’m going to walk in the front door of the castle and start swingin’. We have shit to do.”
That’s become the polite way for me to tell the players to focus up. Occasionally, someone will object and I’ll allow the delay but only for a short time, and once I’ve done something like that, they tend to get their shit together.
I’m not sure what is meant by the DM shouldn’t be making an off-the-cuff ruling whenever dice are picked up. They’re the ones who set the DC’s for checks if they aren’t explicitly laid out in the book. I don’t know how else that’s supposed to work.
I never argue with the DM beyond making a single objection. If they make a ruling I don’t agree with, I will state my case as quickly and succinctly as possible, and if they don’t overturn, I’ll leave it alone and talk with them about it later, when we don’t have a game to play.
I also usually talk with the DM after games to see if there was anything that frustrated them during the session and to brainstorm ways to address it next time it happens. That’s where the “impatient/decisive character roleplay” thing came from.
Hey, sorry if you’ve said this already, but I noticed some of your posts are tagged #overly sarcastic productions, and I was wondering why you put this? f you were sponsored by them or something? Sorry. Have a wonderful day!
Oh, it’s because I’m Red. I’m doing this comic along with the channel now! Probably going to put out a video announcement once the comic gets a little farther along.
-R
Did that video announcement ever get made? Because if it did, I missed it. I only remember some oblique references to it in, like, Trope Talks, I think.
Or has it become a running gag to let people figure it out?
