Naomi walked into the Astronmy classroom and sat down at one of the tables. She looked at the board and then got to work. First, she cut open a garbage bag and use it to line your mixing bowl. Then she put water in the mixing bowl and add dirt, stirring it well. She then added a dash of ammonia and a dash of organic material. She continued to stir the mixture until it was well mixed. She looked up at the board and read the next step. Dry ice? she thought. Better put on gloves. She put on the gloves and put 3 garbage bag inside one another and put the dry ice inside of it. She then crushed the dry ice with the hammer and added it to the rest of the ingredients in the mixing bowl, stirring it vigorously. She continued to stir it until it was almost frozen. She put back on her gloves and removed the mixture and made it into a ball and wrapped it back in the plastic bag. She waited a few minutes until it was completely frozen. She then removed it, still with the gloves on, and put it on the paper plate sitting infront of her, and waited to be told what to do next.
