Xehanna walked into the Observatory. "Good afternoon, Professor." She said smiling. "Yes a lab!' She thought as she looked at the board and rolled her sleeves up while reading the first part of the instructions. She tied her hair back and put on some safety goggles. She grabbed a garbage bag, cut it down and lined it in her bowl. She poured the 2 cups of water in her bowl carefully and slowly sirring in the dirt until it was mixed. She then added a little ammonia and organic material. She stirred until it was mixed very well.

She remembered to put on the gloves just before handling the dry ice, so she did. Xehanna then put a garbage bag inside of another garbage bag and one inside of the first until there were three. She put the 2 cups of dry ice and tied the bag, letting the air out. She began crusing the dry ice with the hammer. After it was well crushed, she poured it in the bowl and mixed it until it was frozen. She put the hammer down; She still hadn't taken her gloves off yet. She took the plastic bag, picked up the comet and balled it like snow. When it was completely frozen she unwrapped it and put it on the paper plate.

She didn't know if she should clean her work station so she did anyways. She picked up he paper towels and wet them a little. She wiped up the excess dirt, ammonia and organic material. Then she took dry paper towels and dried off the table. She rinsed the gloves and put the goggles back. She straghtened the ingredients. Xeh looked around and saw that some people had finished but others were still working. "Great class, Professor!" She said as she waved good-bye to the professor and left the room.
