Victoria walked up the stairs towards the observatory, she was nervous about entering because last time, she got detention. She nervously knocked on the door.

"Sorry professor!" she slowly walked in the lab, she used to love chemistry back in the muggle world.

Victoria walked to the desk and looked at the board, she read the first line and started to cut one of the garbage bags.

She lined the bottom of her mixing bowl and place water in the mixing bowl, she added the sand and started to stir it.

Victoria added the dash of ammonia which smelled like wee and then added a dash of organic material which smelt worse. She put on the gloves and picked up the dry ice in the garbage bags so she can crush it.

Victoria put on the googles and started to crush the dry ice which made a lot of noise but she could take her angry out of it. She then picked it out and put it in with the other ingredients and started to stir virgorously.

Soon her mixture was almost totally frozen, she use her gloves to help her lift her comet out of the bowl so she could shape it.

She used the bag to shape her comet, she unwrapped it when it was frozen and she then used her gloves to put it on the paper plate.

Victoria waited for the professor to have a look at her comet and wondered what they will do with them.
