Marvel Scientists continued experimenting with Carbon Dioxide. Today we had planned to explore Super Volcano Eruptions. By mixing baking soda and vinegar, adding food coloring, and soap, we had ourselves a marvelous eruption. We also tried to see what type of chemical reaction we would get if we replaced vinegar with lemon juice or used baking powder and starch instead of just baking soda. The results were inconclusive. The nature of volcanoes is unpredictable and scientists need to know more about it.
