Now that she had the clay just right in her tank Marie picked up the coral and started to mold it into the clay about 5cm deep. Once that was done she looked up at the board again.
-------------
Time to add some water. Three liters of sea water to be exact. Going to the back again... which wasn't very far for her since she was already at the back, she got the water then took it back to her desk. Very carefully and slowly she poured that water into the tank. She didn't want to pour it too fast taking the chance that the coral would work its way out of the clay. No, that wouldn't be good. She needed it to stay just where it was.
-------------
Once all the water was in the tank she looked at the board to see what she needed to do next. Oh gross, it was time to play with the poo.

Putting her gloves on she once again went to the back to get more water and the mooncalf poo.

Disgusting!

Sitting back at her desk she slowly (so it didn't splash on her) mixed the poo and water until it was all dissolved. Now to add it to the tank. Looking up at the board she frowned when she seen it was only one drop they had to add.

After adding the ONE drop she glared up at the professor. Why couldn't one person have made the solution? What the heck was she supposed to do with this crappy water that she had left? Well, she had a few ideas what she could do with it but that would require taking it with her and she did NOT want to carry that around with her. Instead she would just leave it there on her desk, with the tank and newly re-planted piece or coral.
-------------
She was about to leave... to get away from the stench of the crap in the room when she seen the tag on her desk. Looking over at Ev... who was already leaving, she quickly glanced at her tag to see what they were supposed to write on it. Oh right, her name.

Grabbing her quill she quickly jotted her name on the tag then placed it on the tank using a sticking charm.

After making sure everything was back in her bag (except the gloves, those she would just leave behind. She had more so she really didn't need those anyway) she quickly made her way out of the room. Not before looking over at Jimmy and giving him a little smile as she passed him. Maybe she would look him up later after the homework was assigned and ask him to help her. Right now though she wanted to go back to the castle and get cleaned up and into some different clothes. She didn't want to risk smelling like dung when she met Matty for lunch.
