Pop Rock and Soda Lab

Hypothesis: The Vinegar an Baking Soda Test will be more sporatic than the Pop Rocks and Soda because of the more chemical reaction generated by the Vinegar meeting the Baking Soda.

Results: Our results were matching to the hypothesis again. The experiment was very straightfoward: Put pop rocks in ballon, place balloon on top of bottle, dump pop rocks, watch automatic infaltion machine work. What was idfferent that the balloon was not filled up with helium like it would be normally, but Carbon Dioxide and Water Vapour. These two parts are very different from helium, but are very common and take up a lot of space. The Carbon Dioxide released from the pop rocks reaches the surface of the cola in air tight bubbles. When the bubbles pop, then the gas released into the balloon, inflating it.

We then moved on towards our vinegar and baking soda test. There was varely any vinegar compared to the cola, only 50 mL, barely forming a complete shape at the bottom. The amount of baking soda was also quite minimal: 1/2 a teaspoon. There was some doubt that the experiemnt would carry out as we had planned it to. But, when the baking soda was dropped in, there were bubbles forming almost instantly around the entire bottle. Hundreds of trapped CO2 molecules that are bursting, filling u pthe balloon very rapidly. The vinegar bottle's balloon almost doubled the size of the cola balloon by the end of the reaction. We were correct on our hypothesis.

Conclusion: What happened during this test made our winning streak for our hypothesis score up to 3. Vinegar did have a better reaction than the Pop Rocks because of the more chemical reaction. When we were about to put in the pop rocks, we realized that the carbon dioxide in the candy wasn't chemical, but physical. Chemical reactions usually have a more energetic or crazy reaction than those with physical. Changing atoms can be very dangerous, but affective. This was confirmed when the ballon from the vinegar bottle almost doubled the size of the Coca-Cola bottle. As well as this, vinegar seems to be more sporatic when paired up with baking soda specifically. This goes the same with cola and pop rocks, but the candy isn't the one with the most contained CO2. That catergory belong more to Mentos than anything. Since there was only 50 mL of vinegar inside the 20 fl Oz bottle, there was a huge difference in the amount of liquid in the container. I can't even imagine if we filled the entire bottle up with vinegar, what that will be like.
