Twilight Sparkle and Rainbow Dash were two of the closest friends in Ponyville. They had known each other for years, and their bond was strong. Despite their vastly different personalities, Twilight Sparkle and Rainbow Dash shared a love for adventure and a passion for each other that left them madly in love. So, when Twilight Sparkle invited Rainbow Dash to her laboratory to help her with a new day of experiments, Rainbow Dash jumped at the chance.

Twilight Sparkle's new laboratory was located underground beneath her crystal Castle, and it was filled with all sorts of chemicals, machines, and gadgets. And dumb crystals lined the walls, can't forget about those. Rainbow Dash had never been inside before, and she was awed by the sight of it. Rows of glass beakers lined the shelves, bubbling with strange liquids of every color. The walls were covered in charts and diagrams, and there were piles of books and scrolls strewn everywhere. If Rainbow Dash pretended all the trash on the floor was clothing, it would remind Rainbow Dash of Rainbow Dash's bedroom. Twilight Sparkle was in her element, bustling around the lab, preparing the ingredients for their experiment, overexcited as though Pinkie Pie and Twilight Sparkle had swapped bodies again.

Wait, had a body-swapping episode ever happened to them?

Ah, who cares.

"Okay Rainbow Dash, I have a special experiment for us today," Twilight Sparkle said, turning to face her friend. "I've been working on a new spell that will allow us to create a special potion that can change the color of an object."

Rainbow Dash was intrigued. "Really? So I can make everything as beautifully purple as your gorgeous eyes? That sounds amazing! How does it work?"

"Well, it's a combination of magic and science," Twilight Sparkle explained. "I've been studying the properties of light and how it interacts with different substances. And I've discovered that by mixing certain chemicals together, we can create a potion that will cause light to refract, changing the color of an object. Today, we're going to combine random ingredients at random in the hopes that we eventually figure out what combination of items produces a colour changing effect."

“That seems kinda dangerous.”

“Do you have a problem with that?”

Rainbow Dash's eyes were shining with excitement. "Danger is my middle name! Actually, it's Sprinkle, but whatever. Let's get started!"

The two ponies got to work, carefully measuring out the chemicals and mixing them together in a large glass beaker. As they worked, Twilight Sparkle explained the science behind the experiment, and Rainbow Dash was amazed by the complexity of it all before she started tossing bat wings and newt eyes and troll gristle and ogre fat and tiny plastic Rainbow Dash figurines into random bubbling vats of purple, yellow, green, orange, and milky white liquid respectively.

“So what happens now?” Rainbow Dash asked.

“We'll find out in two hours when these potions are done. In the meantime, let's talk about our feelings!”

Rainbow Dash gagged. “I can't think of anything I want to do less. Can't we talk about Spike's mental health instead?”

Twilight Sparkle looked at her like an unfunny political talk show host visually signalling doubt and derision to his crowd of automatons who clapped when they were told to and booed when they were told to. “RD, you know nopony cares about that.”

“Yeah...” Rainbow looked away, irritated. “Can't we talk about anything else anyway?”

Rainbow Dash had been acting strangely for the past few days, and Twilight Sparkle was starting to worry about her friend. She could tell that something was bothering Rainbow Dash, but every time she tried to bring it up, Rainbow Dash would change the subject or brush it off.

"Rainbow Dash, I know something's been bothering you," Twilight said gently. "And I want to help. Can you tell me what's going on?"

Rainbow Dash fidgeted and looked away, avoiding Twilight's gaze. "It's nothing, Twi," she said. "I'm just a little preoccupied, that's all."

But Twilight wasn't going to let it go that easily. "Rainbow Dash, we're friends. You can talk to me about anything. I'm here for you."

Rainbow Dash let out a sigh and finally looked at Twilight. "Okay, fine," she said. "It's just that... I've been feeling really confused lately. About a lot of things."

Twilight nodded, encouraging her to continue. “It's okay, Rainbow Dash. You don't have to hide your true feelings from me.”

“Do you realize what you're saying when you talk like that?” Rainbow's wings flapped in irritation. “I can never tell if you're flirting with me or not.”

“Would it be a bad thing if I was flirting with you?”

“Maybe.”

“Why? Don't you like me?”

“Of course I like you!”

“So what's the problem?”

“Maybe I don't think I'm good enough for you!”
Twilight was taken aback. "What are you talking about, Rainbow Dash?" she asked. "Of course you're good enough for me. You're one of the most amazing ponies I've ever met."  

But Rainbow Dash was inconsolable. "No, I'm not," she said. "I feel like I'm always messing things up, like I'm not smart enough or strong enough to be your friend. I feel like I'm not worthy of your love and friendship."  

Twilight's heart ached for her friend. She took Rainbow Dash's hoof in hers and pulled her close, enveloping her in a warm hug.

"Rainbow Dash, listen to me," Twilight said, her voice filled with love and tenderness. "You are worthy of my love and friendship. You are one of the strongest and bravest ponies I know. And you are more than enough for me, always."

Rainbow Dash sniffled and looked up at Twilight, her eyes filled with tears. "Really?" she asked, her voice small and vulnerable.

"Really," Twilight said, smiling at her friend. "I love you, Rainbow Dash. And I always will, no matter what."
Rainbow Dash let out a sigh of relief and snuggled closer to Twilight, who held her tightly and whispered soothing words in her ear. And as they sat there, surrounded by the warmth and love of their friendship, Rainbow Dash finally felt like she was enough, just as she was.  

"I don't know what I want," Rainbow Dash whispered, her voice filled with frustration. "I don't know what my future holds, or what I'm supposed to do with my life. And it's starting to scare me."

Twilight reached out and took Rainbow Dash's hoof in hers. "It's okay to be scared," she said. "But remember, you're not alone. I'm here for you, and I'm always here to listen."

Rainbow Dash smiled, and a tear rolled down her cheek. "Thanks, Twilight," she said. "You're the best friend and wife anyone could ask for."

And then, without warning, Rainbow Dash leaned forward and wrapped her hooves around Twilight in a tight hug. "I love you, Twilight," she said, her voice filled with emotion. "I love you so much."

Twilight was taken aback, but then she smiled and hugged Rainbow Dash back. "I love you too, Rainbow Dash," she said. "And I'm here for you, always."

From that moment on, Twilight knew that she and Rainbow Dash would always have each other's backs, no matter what the future held. And she was grateful to have such a wonderful friend in her life.

As the day went on, Twilight Sparkle and Rainbow Dash laughed and talked, thoroughly enjoying each other's company. The experiment had brought them even closer together, and they both knew that they would never forget this special day in the lab.

As the experiment continued, Rainbow Dash became more and more confident with the chemicals and the potions they were creating. She started to take risks, adding more of this ingredient or that, wanting to see what would happen.

Rainbow Dash noticed a high pressure container full of some strange purple bubbling concoction suspended over a Bunsen Burner. The glass container was a long, thick, cylindrical shaft, with two round bulges at the bottom, and despite the thick brown cork firmly wedged into the shaft, the noisy hiss of steam started to escape from the container, along with a rush of white foam.

When Rainbow Dash turned the Bunsen Burner up, more white foam erupted from the glass in a tremendous burst.

“Hey, Twilight, look!” Rainbow Dash laughed. Twilight looked. “Me inside your mom!”

“Get down!” Twilight screamed in a terrible panic, diving for Rainbow Dash and pulling her to the ground, shielding her with a wing and a magical shield spell.

The mixture started to boil and steam and shoot foam harder than ever before, and before either of them could react, there was a loud BOOM.

The explosion sent glass shards and chemicals flying everywhere, and Rainbow Dash was thrown back against the wall. She was dazed and disoriented, and when she opened her eyes, she saw double. Triple.

"Rainbow Dash, are you okay?" Twilight Sparkle asked, looking at her friend with concern. “How many hooves am I holding up?”

Rainbow Dash rubbed her head and groaned. "Sixty nine.”

Twilight rolled her eyes. “Yeah, you're fine.”

“What happened?"

"I don't know, Rainbow Dash. I don't know. Something just... exploded. I'm so glad I was able to protect us."

Rainbow Dash was horrified. "I'm so sorry, Twilight. I didn't mean to cause all this damage. And I could have hurt us both."

Twilight Sparkle smiled reassuringly. "It's okay, Rainbow Dash. Accidents happen. It wasn't your fault. But what's important is that we're both safe now."

Rainbow Dash nodded, grateful for Twilight Sparkle's quick thinking and bravery. She knew that she had a lot to learn about science and safety, but with Twilight Sparkle by her side, she was eager to continue her experiments.

[i]Dear Princess Celestia...

Today I learned a lot about lab safety, and... Hey, Spike, you finish the rest, okay? I've gotta go and make peace with the Griffons. What do you mean, what do I mean? I mean I've got to go and lay an egg. A Zebra egg. ...Seriously, Spike, you need to get out more! Hasn't Twilight explained to you what a euphemism is? I'm going to go and visit the little filly's room. ...What does Scootaloo have to do with- Spike, I'm going to explode if I don't go and take a massive dump in Twilight's toilet and clog this dumb crystal castle's dumb crystal pipes so hard Twilight will shove you down the toilet to unclog the pipes again. Finish this letter for me, okay? How do I want you to- I don't care how you write it! Just finish the stupid letter and send it already!

Dear Princess Celestia,

I hope this letter finds you well. I wanted to write to you about a very special experience I had today in Twilight Sparkle's laboratory. I had the opportunity to assist Twilight in a scientific experiment, and while it was a lot of fun, I also learned a lot about lab safety.

As you may know, Twilight's laboratory is full of chemicals and machines, and I was a little intimidated at first. But as we worked on our experiment, Twilight took the time to explain the science behind everything and taught me about the dangers of certain chemicals.

Unfortunately, I made a mistake during the experiment and cranked a Bunsen Burner up to 11. Why are they called Bunsen Burners when Robert Bunsen doesn't exist in this universe, anyway? Couldn't we think of a pony pun for their names? Thankfully, Twilight was there to protect us both from the explosion and keep us safe. It was a frightening experience, but it taught me a valuable lesson about being careful and responsible in the laboratory. I almost turned myself into Zap Apple Jam! I bet I'd taste awful in a sandwich. Not like Twilight. She tastes amazing. Just like her mom. They are also great in a sandwich, if they are the bread and I am the filling. If they're all over each other that's kinda weird but if they're both all over me it totally doesn't count as incest, they're both just showing affection towards me, Rainbow Dash. At the same time. In the same bed. And it's totally not gay. I mean, it is, we're all female haha, but it's totally not incest.

From this experience, I learned that safety should always come first in a laboratory, and that it's important to understand the properties of the chemicals and materials you're working with and familiarize yourself with the effects of heat on the ingredients you are working with. I also learned that it's important to have a partner who you can trust and who will help keep you safe. It's also important to make cock jokes constantly because they are never not funny.

I want to thank Twilight for her guidance and for showing me the importance of proper lab safety. I also wanted to thank you, Princess Celestia, for sending my beloved wife to Ponyville and giving me the opportunity to meet and learn from amazing ponies like Twilight.

I look forward to continuing my scientific adventures and learning even more about the wonders of magic and science.

With gratitude,

Your faithful student,

Rainbow Dash.

PS – Spike is totally awesome and the coolest dragon ever and him and Rarity are totally going to have a million babies one day and they'll live happily ever after and I'm sure he totally won't die alone and miserable surrounded by candy coloured marshmallow horses who view him as a nuisance if they can't use him as an object.[/i]
