 * THE SUBLIMATION RATE OF DRY ICE IN WATER, GATORADE, AND MELLO YELLO**

The purpose of the experiment that was done was to determine what liquid sublimes most when dry ice and Dawn dish soap were added. The liquids that were tested were warm water, Mello Yellow, Gatorade, and Pepsi. The hypothesis that was made for this experiment was that the two carbonated drinks (Mello Yellow and Pepsi) would sublime the highest out of all the liquids. This was hypothesized because it was thought that the bubbles would enhance the foam and/or fog that sublimes from the dry ice. To do this experiment, first, water was inserted into a 250 mL beaker and then dry ice and 10 mL of blue dawn dish soap were added and then observed and measured. This was measured by putting the ruler on the edge of the beaker and how far the foam went up the ruler. This was repeated three times and repeated with a test tube with a smaller piece of dry ice and 5 mL of blue dawn dish soap. It was found that the hypothesis was wrong. Water sublimed the most out of all the liquids. It was thought that this happened because of the difference in color and the carbonation that water sublimed most. In the second experiment, non-crushed dry ice sublimed much more than crushed dry ice. In the third experiment, it was found that when orange and blue dawn dish soap were compared when put in dry ice and water that blue dawn dish soap worked much better than orange.
 * ABSTRACT **

For future experiments, different liquids could be tested such as Powerade, Sunkist, Fanta, and Hawaiian punch. The different types of water could also be tested, such as Deer Park, Sobe Lifewater, Fresh Spring, and Dasani. Some interesting findings about my experiments were that the color of the dawn dish soap affected the amount of the sublimation considerably. Another was that crushed dry ice actually did not make more sublimation than regular dry ice. This was interesting because it was thought that the crushed dry ice would make more places for the fog and/or foam bubbles to come up.
