Okay I feel stupid for not knowing that soda ash is just sodium carbonate. You can make it by baking baking soda (sodium bicarbonate) at 200 degrees for an hour. I already have some from when I was making ramen noodles.

I keep seeing this term ‘biological male’ being thrown around. There are lots of reasons why this is an innacurate and unhelpful description, but I’d like to examin just this term for a moment.
What exactly is a ‘biological male?’ The definition of biology is “the physiology, behavior, and other qualities of a particular organism or class of organisms.“ So let’s brake that down a bit. In refference to humans that means organ structures and chemicals that run those organs. So when talking about biological sexes, we’re probably referencing a certain set of average characteristics shared by people with XX chromosomes, XY chromosomes, or other sets of chromosomes which are part of natural human variation like XXY, XYY, XXX, XXXXY, X, XXXXXX, and XXXY (learned about those in biology class. It’s really cool how much more diversity there is to human biology than you generally think about. If we’re basing sex off of DNA, there are indeed WAY more than two sexes).
Now the way that any of those sets of DNA (which are known as genotypes) translate to how the body looks and works (phenotypes), is by making chemicals. Those chemicals are what build all the organs and keep them running the way they do. DNA isn’t the only thing deciding how much of each chemical there is though. Environmental factors like the food we eat, medicine we take, other organisms living inside us like bacteria and viruses, chemicals we absorb from the environment, and even stress massively impact body chemistry, often completely overriding DNA. So sometimes you might have the genotype for one thing and end up with a different phenotype. Like people who were born with tall genes but end up short as adults because during the time they were developing they didn’t have access to adequate nutrition. Their DNA might say one thing but in reality, they turned out as something else. The short person with tall genes is still short, regardless of what their DNA says.
Phenotype can also be directly changed by outside forces, like getting a limb blown off in an explosion, getting your ears pierced, or having surgery. These overide both DNA and body chemistry. A person with the DNA and chemicals to have two arms but had one arm chopped off is phenotypically a one armed person.
When reffering to different sexes, we’re usually talking about generalized groupings of phenotype, like gential organs, bone structure, musculature, hair growth, and fat distribution. These phenotypes are generally determined by chemicals called hormones. Just like any other chemicals, these too are impacted by environmental factors like what we eat and what medicines we take. So when someone takes a medicine that alters their hormone levels, that alters their phenotype. Just like how growing up with healthy foods and vitamins can help kids develop strong and healthy bodies, medicines like puberty blockers and hormone replacement therapy lead to bodies developing differently. These phenotypes can of course also be altered through surgery by deconstructing and reconstructing different parts of the body like genitalia and facial bone structure. By changing the chemicals and organ structures they have changed the biology.
So what is a ‘biological male?’ A biological male would presumably be someone with the general phenotypes of the group called males. If someone does not have those phenotypes, it wouldn’t make sense to call them a biological male. So according to the definition of biology, a trans woman whose physiology, behavior, and other qualities align with those exhibited by females is not a biological male. She is a biological female.

You know what really annoys me?
In so many sci-fi shows and movies where they show a character undergoing a major dna change, they'll zoom into their bloodstream and show their red blood cells mutating.
This would be perfectly fine except for the small fact that
Red blood cells *don't* have dna

Ah mmmm well
You know how in mermaid stories, the mermaid is typically the dumber one? I present to you the "and they were both scientists" plot.
Basically the concept is that mermechs and regular mechs can't talk to each other. But luckily even if they speak different languages they still use the same math~
I discovered a bunch of simpatico mer-fics. So. I wanted to do something with this concept too haha. If some physicist happens to read this - feel free to laugh at me. I know nothing about science👍
I don’t know if I’ll continue this thing. Should I. Idk. It’s midnight I might be going crazy lol. I made that cover anyway bc I love making covers hehe

Bright Hope, Mighty Will
The Green Lantern Corps have lost many members over its years— a risk that came with maintaining the peace as told by the Guardians. Most of the rings reassigned to a new member of its given sector but on occasion there would come those that were so attached to its wielder that they would not accept another unless they resonated with their predecessors ideals.
It’s one such ring that had been on Oa with no new lantern to wield it. Or it had been.
The Blue Lanterns were still a growing group with whom the Corps had a close alliance thanks to their symbiotic relationship; after all a Blue power ring was at its highest potential when near a Green power ring and vice versa. So why not look for users together?
The rings were set off as a pair in an attempt to create a powerful Union and birthing the most powerful duo either Corps had ever seen.
Meanwhile in Sector 2814, on the third planet from its star— Earth, a small family from the Midwest were camping out in the woods after their youngest begged to see the shooting stars where they’d be the most visible. The oldest child explained to their parents that it was a good way to channel the younger’s passion for space and science much like their own. Everything had been well until the elder duo’s sensors brought up a strange signature from deeper in the wood— Ecto-entities or ghosts as they’d called them. Before being able to drag the children with them the youngest stood his ground and refused to be taken away from his stars, the elder assured that she could take care of her younger brother and that they’d be fine alone (they were alone even when in the same house more often than not)
The sun had since set, the telescope set up, blanket had been laid with snacks for them to consume as they sat in wait with jackets to help with the night chill. The duo sat near the campfire as the younger's anticipation grew but the thought of their parent's absences did as well. They'd been left home alone before but they were only 8 and 10 years old, in the middle of the wilderness with no way to guide them back home or even find where their parent's ghost hunting led them.
"Don't worry little brother, I'm sure mom and dad will be back soon"
"Ye-yeah! Besides mom knows how to kick butt, they'll be fine"
"Look!"
The duo took their gazes to the skies as the twinkling night was accompanied by steaks of white dashing by. The older grabbed her slightly old model camera and took photos of the unsuspecting boy's awe filled gaze before he could complain. He stuck his tongue out at her before turning to his telescope, doing his best to follow the streaks in the sky until no longer visible to him. The girl just took to taking some more photos to show their parents once they'd returned. It'd go on for a while like that, the stars as their only witnesses as they joked around.
"Hey that one's green! And that one's blue!"
She lifted her head from looking at her camera's saved photos to find the twin streaks flying together, a quick click of her camera to save such a strange occasion. She wasn't an astronomy expert but she didn't think shooting stars came in those colors. Taking her gaze off of the small screen and looking back up she noted the bigger size.
"Are they getting closer?"
"Maybe they'll land near here. How cool would it be to see them up close?!"
It was as though those words triggered something as the two stars seemingly stopped flying and began their rapid descent. Straight for them.
"They're headed right for us!"
"Run!"
The duo quickly picked up their discarded flashlights and began running away from the clearing their parents had chosen. No matter how fast or further away they got the stars still trailed towards them. The numerous twists and turns never deterring the streaks of light, even as the elder held the younger's hand in an iron grip to prevent them from losing each other or as the younger turned them around and took haphazard turns in an effort to get them away.
"Everything's gonna be alright!"
She panted as they approached another clearing, no idea where their own was but still looking and seeing the stars much closer to them, the lights were blinding. She felt her body get pushed aside and the roll of cold grass on her back, hair getting tangled with small twigs and a familiar but smaller body land on top of hers.
"Look out!"
They closed their eyes and braced for impact feeling a sudden breeze and a slight shake but nothing else. Until they heard different voices echo. Looking gazes and noticing the glowing eyes the other had they sat up--- only to be met by glowing, floating ----rings?
[Sentience located]
[Daniel James Fenton of Earth, you have been chosen]
[Jasmine Dahlia Fenton of Earth, you have been chosen]
[You have the ability to Overcome great fear]
[You have the ability to instill great Hope]
[Welcome to the Green Lantern Corps]
[Welcome to the Blue Lantern Corps]
A bright flash of blue and green surrounded the duo, hands still clasped and feeling a tug on their unoccupied hands, the warmth traveling on their bodies before disappearing altogether.
"Jazz what are you wearing?"
"What am I wearing!? What are you wearing Danny? Is that your old astronaut costume?"
Jazz noted the blue ring on top of her opera gloved right hand, also clenching the handle of a blue lit lantern? She could feel her knee length puffy blue dress move with the night breeze but didn't feel cold. White boots with blue bottoms kicked a pebble to the side, hearing it hit the nearby lake. Given the full moon she took a gaze at her reflection, finding her usual teal ribbon replaced by a giant blue bow at the back of her head and her eyes glowing a brilliant blue.
Danny was busy looking at his green suit, looking much like the costume he wore in a near daily basis when he was five until he started school. His own white gloves had puffier cuffs which reminded him of the astronaut costumes he and Tucker had looked at online for Halloween the year before, green ring also on his right, shaking the green weird lamp in the process. He pulled at the black suspenders before joining Jazz at the lake. His raven locks now had a single green streak near his bangs and icy blues now a vivid green.
"Cool"
Jazz was panicking, wondering what this could mean; what was a Blue Lantern anyway? Why did it choose her? And why was Danny green?
"Whoa!" Her glowing eyes turned to Danny but couldn't find him, hearing the sudden clatter of something falling on the floor and seeing the lantern rolling on its side, had he fallen in the water?!
"Danny!"
"Up here!" her eyes widened as he little brother flew above her, laughing as he looped around in the air, "C'mon Jazz!"
"How did you do that?" her eyes never leaving the faintly green glowing boy, "Can I do that?"
[You can. Just have Hope]
Trusting the voice in her head she reassured herself that they would be fine before feeling the ground disappear from under her feet and got closer to Danny, dropping her own lantern next to Danny's. She felt her surprise turn into a smile before doing a cartwheel in the air and the giggles escape from her.
Neither took track of time as they flew above the clearing before Danny had the idea to race above the lake, streak of blue and green reflected on its surface as it rippled from their speed. It wasn't until they flew back to the clearing that they remembered--- they had no idea where they ran off to. There hadn't been a lake where they'd set up camp.
"Mo-mom and dad will find us Danny! We'll be okay" They had to be okay, they would be fine. The idea of flying above the trees to look for their clearing was tempting but she had no idea how long it would take; did these things run on batteries? Would the power run out soon? Can they even take off these outfits? It'd be weird to be stuck like this for forever. If mom and dad find them what will they think of the glowing? It reminded her a bit too much of how the ectoplasm in the basement glowed whenever she or Danny were dragged downstairs and the substance covered near all the surfaces (that's when they'd know dad was making them clean up)
Whilst Jazz marinated in her thoughts and worries Danny couldn't help but think if there was a way to ask for help, though even if they had phones he doubted they'd even have service or know how to guide help towards them.
[Activating Emergency Beacon for Sector 2814]
"Huh? Emergency beacon?"
"What was that Danny?" Jazz snapped out of her thoughts as she heard his confusion, noting the slight pulsing now coming from his ring.
"I-I think my ring asked for help?"
"...Let's hope that's a good thing "
The brother-sister duo took to sitting by the lake once more, still viewing the stars above and keeping an ear out for any sign of their parents--- they were never quiet for too long. Especially when 'ghost-hunting', not that ghosts actually existed.
They were starting to get hungry again, having not touched their assorted snacks before the whole fiasco began when a steak of green, followed by another, approached the horizon. The first stopped, the second following suit... Were they like them? It looked like two people flying now that they weren't moving so fast. They were too far to properly see but it looked like they were searching for something.
Danny's ring flared up in quick brilliant flash before going back to its blinking; it seemed that was the cue the two in the sky were looking for as they made their way towards them.
"I think that's our ride Jazzy"
The duo finally hovered above the lake shore, the surprise clear on their faces even as one had a mask on.
"Hello, I am Green Lantern John Stewart of Sector 2814" the first man with matching vivid green eyes like Danny elbowed the man next to him.
"Uhh and I'm Green Lantern Hal Jordan of Sector 2814" he said sheepishly, running his white gloved hand through brown locks of hair. "You're the ones who send the distress call, what sector are you from?"
"Sector?" the duo looked at each other confused before Jazz remembered what the rings had said. "I- I think they said 2814?"
The duo looked surprised, disbelief easily conveyed even though Mr. Jordan's mask, actually he seemed more surprised than Mr. Stewart. "I'm sorry but what planet are you from?"
"Earth? I mean its not like--- Are aliens real!?" Danny's wariness disappeared and hovered in the air as he said it, "That's so cool!"
"You two are Earth children then" Mr. Stewart's eyes gained a dark look as he said so, "How long have you had the rings?"
"Umm I'm not really sure" Danny turned to his sister for guidance only to find her rubbing her arm nervously "Maybe an hour or two?"
Mr. Jordan's look matched Mr. Stewart's, like they were mad but they didn't seem mad at them like the teachers would when they caught him and Tucker talking during class. It was like whenever mom and dad's inventions malfunction and they'd go to school with bruises. (Those days mom and dad would mention their teachers calling them, they were always busy with the portal and never answered)
"Do you know what those are?" Mr. Jordan bent down to Danny's level, pointing at the matching green ring. Danny looked at his and wiggled his fingers.
"Not really? The voice said welcome to the Green Lantern cops?"
"Close, little man" Mr. Jordan chuckled, "My friend and I are part of the Green Lantern Corps. We help protect the universe, pretty much space cops if ya ask me"
"You get to travel into space! Awesome!" Danny literally brightened as his green glow intensified. "But why isn't hers green?"
"Your friend is actually part of the Blue Lantern Corps. They're a little different from us but we work together from time to time. They like to spread hope throughout the universe"
"Hope. It said I had the power to instill great hope. But why me? And why did they choose him?" her voice wavered as she turned to Mr. Stewart with a grave lookin his eyes.
"That... That is something neither of us can answer for you" he admitted, a solemn lookin his eyes as he placed a hand on her shoulder, "But we'll do our best to help you two with this"
"Its unprecedented for either Corps to choose children" Mr.Jordan frowned before looking towards Danny again, "What are you two doing in the middle of the woods?"
"I wanted to see the stars" Danny admitted sheepishly, all of this started from his request to their parents. They wouldn't be in this mess if he just watched from home like always, heck Mr. and Mrs.Foley had offered to take Danny and Tucker camping once school let out if he wanted to (but no he couldn't wait a month, he needed them now). "So mom and dad brought us camping but then the stars--- the rings started chasing us and we got lost"
"That must of been scary huh guys?" Mr.Jordan gave a look to Mr.Stewart and the man walked away a bit, placing a finger into his ear and whispering. How weird.
"So you guys are siblings?" he turned to Jazz, she just nodded slowly, took a deep breath and looked him in the eyes. She kept rubbing the blue ring on her hand as she did. "Do you guys mind telling me your name?'
Jazz still had that worried look in her eyes, like when she knew the turkey would come back to life in any second but mom kept saying it'd be fine. (Jazz was always right, it was always the same every Christmas). His sister liked to think she was a grown up and didn't get nervous talking with strangers but she was still a kid like him. He would be brave for Jazz!
"I'm Danny and that's my big sis Jazz"
"Its nice to meet you two, or well at least know your names now?"
"Jordan"
"Hold right there"
The two adults just kept talking in whispers, looking back at them every few seconds, Jazz wasn't sure what to make of them but they were the ones who knew the most about the situation. Danny also had a pretty good sense for people and they seemed friendly but she also knew better than to trust complete strangers. Stranger danger was very much ingrained to them at a young age. Jazz knew it was rude but couldn't help but hear Mr.Jordan's outburst of "Seriously, nothing? Its been hours"
It seemed like forever before the adults came back and gave them strained smiles in turn.
"Well kids we're going to help you guys find your camp and make sure you get back to your parents" Mr.Jordan winked.
"We'll also explain more about the rings and what they mean while we wait. Sounds like a plan?" Mr. Stewart made sure to look at them in the eyes and didn't move until they both nodded in agreement.
"Okay"
The brother-sister duo didn't know what they were getting into when they went camping that day but everything was in motion, a new path diverging in time to create a brilliant new future; tragedy, love, and courage would always be on their path no matter how much he'd tried to avoid, it was inevitable. He could only witness as they embarked on this journey together and bring about the Rebirth with allies at their sides.
And he couldn't wait to meet them again, in due time.

Adhd? Nah nah. It’s a CPU problem, my dude. My processor is super outdated and doesn’t have nearly enough threads to process daily functions. Keeps having to restart tasks, because it doesn’t have enough power to keep track of multiple things at a time. That’s why I get distracted so easily. No other reason.
