potion in the making (CLOSED)

Alyssa was so close to finishing her potion, she needed it for a prank. She wasnt sure if she would get in trouble for using the potions classroom, but she really needed to get it done. Hoping no one came in and messed her up, but almost instinctively knowing that wouldnt be posible, she added another ingrediant and started stirring clockwise.

Casey walked by the open Potions classroom door, looking for her sister. Seeing her in the empty Potions classroom and obviously concentrating very hard, she sat down on the floor outside with a book to wait.

Letting the potion cool a little Alyssa thanked any spirit or god listening, that she wasn't interupted. Once she bottled the potion, she walked into the corridor, not noticing the smell of someone else, to lost in her own thoughts. Needless to say, she ended up tripping over her adopted, but practically, twin sister.
"Oh! Hey Casey! What are you doin here?" She asked as innocently as possible from her place on the floor, while trying to unsuspiciously hide the bottled potion.

Casey noticed the potion bottle Alyssa was trying to hide behind her back, as well as the white sheen that represented the innocence her sister was going for over the deep green she associated with being sneaky.
See, Casey had the ability to read emotions like she read books. They showed up as films of color in the corners of her vision. Most of the time it was a complete rainbow from everyone around her unless someone was feeling particularly strong or was really close to her.
"So," she sadi, adoptiving a conversational tone. "What's the potion do?"

"Uh, what potion," then seeing her sister's face she said, "Oh! The one I was working on, well that was a boil potion I needed to redo and turn in for class." Alyssa lied, hoping her sister took the bait, even thought Alyssa almost never had trouble with potions, and technically wasnt even signed up for them this term.
Alyssa had tucked the potion into the back pocket of her jeens, which were concealed by her sweatshirt, as it was a weekend.

Casey raised one eyebrow. "You do realize I know that you're lying, right?" She tapped her skull. "You show up brown and brown means guilty and you always feel guilty when you lie. Anyway, that potion was blue. Boil potions are green."

Alyssa cursed inside her head, how could she have forgoten her sisters power.
"Ok, I'll tell you, but not here. I dont know who all could be watching." What she didnt count on was the person who followed then as they left down the hall.

Casey let herself be pulled along, curious as to what would happen.

When Alyssa thought they had reached a safe place, she told her sister all about the prank, to squirt a potion that'll turn everyones hair blue into the main pitcher in the kitchen, so everyone who drinks pumkin juice the next morning will have blue hair by lunch.

Casey grinned. "That. Is. Awesome. Remind me to drink pumpkin juice that day. Blue hair would be so cool!"

Alyssa laughed, "Yeah! The only problem, is I dont have any reverser made up yet!"

"So?" Casey responded. "Blue hair would still be awesome and I'll wear it as long as it takes!"

Alyssa laughed, "Alright! Well, if we want this to work for the next meal, we need to put it in the pitchers now!" Alyssa dragged Casey with her towards the kitchen.

Casey walked down to the kitchens exitedly, grinning when their plan went on without a hitch. This afternoon was going to be fun.
