During the down time Morgan and I had, we decided to help Ivy when she was left to do a lab by herself. She seemed lonely and somewhat stressed because 2 of her partners weren't there. Morgan and I were launching our rocket later in the day, so we decided to help Ivy. The lab she was doing was making bath bombs which fizzes and makes the water turn a certain color and gives off essential oils. They're basically like bubble baths, but without the bubbles. First, we helped measure and mix the solution, making it soft enough to create a ball and not crumbling. Then, we put them into the tennis ball molds, which Morgan and I cut with Erika. They were really hard to mold because we weren't sure how to take them out of the tennis balls without damaging the shape. During the process, Ivy taught us about the chemistry behind bath bombs because it's really popular nowadays. The reason bombs fizz because they release CO2 which is a chemical reaction that occurs when the citric acid comes in contact with water. Since the citric acid is an acid, and the baking soda is a base, the bath bomb is neutral. However, once it hits the water it unbalances it. The bath bomb then dissolves, releasing the essential oils and colors.
