Marsella Issue Date: October 1994 Volume: Page Number(s): 10-12 ARTICLE SYNOPSIS (minimum 1 paragraph [six sentences]) Explain the main points of the article: Chemists have been making bubblegum since the early 1900’s. For the sake of it, people have been chewing on things like tree sap and whale blubber long before bubblegum. In order to make bubblegum, there are measurements that need to be taken into consideration, such as: the amount of rubber, different flavors, and the amount of sugar. Too much rubber will make the bubblegum too firm and not enough rubber will break the thin film too easily when trying to make a bubble. Chemists don’t want to upset parents so they make sure when bubbles are blown they don’t exceed the size of a grapefruit. To help soften bubblegum, chemists make sure to combine it with products that will soften when the saliva of the chewer is associated. To make gum taste like fruit, products like limonene (an essential oil in fruit) are added and cannot dissolve when it combines with saliva. 1. What did you learn from reading the article? (Minimum 3 sentences) From reading this article I learned the chemical makeup of bubblegum. I learned that rubber is essential in making the bubblegum stretch. Chemists add humectants (which are chemicals that draw water) to make the gum base chewable. And that the measurements of creating new types of bubblegum are based off of trial and error. 2. How is this article related to chemistry? (Minimum 3 sentences) This article is related to chemistry because it explains that in order to mix water-soluble and water-insoluble materials emulsifiers (chemicals that allow water-soluble and waterinsoluble materials to mix) must be added. It also explains that the chemicals in it must be measured as exact as possible because with too much rubber, the bubblegum will not be chewable and with not enough rubber the film will break too easily. The rest of the chemicals are to control the size of the bubbles and either help the rubber stretch more or to add flavor. 3. Pick out two important points made by this article that you think other people should know about. Why? (2 paragraphs, one for each point) One important point made by the article is why the bubbles don’t get very big. The largest bubble blown was almost 24 inches in diameter. But, chemists do not like to push away parents so they restrict the size to no larger than that of a grapefruit. People should know this fact so that they do not hurt themselves try too hard to make a bubble get bigger than their head and to ensure messes stay within cleaning accessibility. A second important point made by this article is how and what chemists do and use to restrict the bubble’s size. Chemists use the air temperature. When the air is warmer, the gum is more easily chewed. When the air temperature is colder, the gum becomes harder to chew. The temperature in our mouths is warmer than the temperature outside our mouths and as a result, the more times the bubblegum is blown the less elasticity there is in the bubblegum making it harder and harder to chew. People should know this fact because, the next time they wonder why they keep paying for more and more gum that easily loses it’s chewing ability and flavor, it is due to blowing bubbles. Also, over-chewing hard things can result in pain of the jaw area.
