Eliza got up and got her vial,she then went to the collect her ingredients.She sat down and started to brew the potion.

First she Set the water to a boil and added salt, stirring clockwise until all the salt had dissolved,a handful fell to the floor but she didn't notice.

she then added the Powdered billywig stings to the boiling salt water, stiring counter-clockwise 12 times this is tiring!she thought ,switching hands.,then she stired it clockwise twice and repeated it six times.by that it felt like her hand was about to fall off!!

She then Carefully added the essence of firefly, one drop at a time,Eliza read what to do next and couldn't beleive her eyes.she looked at her hands No again!
she started stirring 6 times counter-clockwise then clockwise twice in between each addition of the essence of firefly.

She reduced the flame and let it simmer for 20 minutes before allowing the potion to cool ,while doing so she rested her hand I never knew potion-making was so hard!She thought ,shaking her hand from side to side to get her wrist non-numb.
She then Carefully used a ladle to pour the potion into the vial ,making sure it was full to the brim before closing the lid. She filled it just too much and a spoonful of it went spilling onto the floor.

She took out her wand and cleaned it up before bring up her vial to the Professor.

Once she gave it up to him ,she cleared her desk and sat down ,writing down the instructions just incase she might be asked it later on.
