Title: The Sweetness, Stretchability, and Volume of Bubble Gum

Objective: The objective of this experiment is to find out which of the three types of bubble gum contains the most sugar, which type of bubble gum stretches the furthest, and which type of bubble gum takes up the most amount of space. Would it be best to buy bubble bum that blows the largest bubbles or to buy gum that has the most sugar and largest stretchability? These are the things we will be exploring through the course of this experiment.

Main Ingredients:

Nutrition Facts:
Bubble gum has no real nutritional value.

A bubble is formed by chewing a piece of gum, and pushing it towards the front of your mouth. The gum then stretches out and cover the front portion of your tounge. Lightly blow from the back of your mouth into the bubble gum, and it will inflate. It is important that your lips are kept in a whistling-like position.

The Use of Sugar in Gum:
Sugar has been used as a sweetener in bubble gum for many years.

Stretchability of bubble gum:
The gum base causes the bubble gum to stretch. Gum base contains a property called visco-elasticity. The gum becomes more stretchy as you chew on it because the base is made of a long string of molecules entangled within eachother. As you chew, saliva slides inbetween the molecules, which causes them to slip by eachother more easily.


Sugar Test

Stretch Test

Volume Test

Many conclusions can be made about Bubblicious, Bazooka, and Doublemint bubble gum through this experiment. The first experiment performed was the sugar test. Each type of gum was weighed, chewed until there was no flavor left, and weighed again. The difference between the initial weight and the ending weight was the amount of sugar the gum contained. Bubblicious bubble gum contained the most sugar. However, Bubblicious weighed the most to begin with. Therefore, the initial weight of each type of gum must be divided to be equivalent to the weight of the other two types. Next, the ending weight of the gum in each trial must be divided by the number that divided into that type of gum to equal the other two types. Now one can find the gum with truly the most amount of sugar. The average results of the amount of sugar the gum contained were found by this step by step process. Because the results were very complicated decimals, the average initial weight for each type of gum and the average ending weight of each type of gum was rounded to the nearest .5 of a gram. The rounded average initial weight for Bubblicious was 8 grams, for Bazooka 5 grams, and for Doublemint 2 grams. The rounded average ending weight for Bubblicious was 2 grams, for Bazooka 1.5 grams, and for Doublemint 1 gram. After this step, the difference of the initial weight ending weight for each type of gum was found. The weights were then made into proportions
(Difference in weights/initial weight). The proportion for Bubblicious was 3/4, for Bazooka 3.5/5, and for Doublemint, 1/2. After the proportions were found, a common denominator had to be found. This lowest common denominator r was 20. After the proportions were changed, Bubblicious was 15/20, Bazooka was 14/20, and Doublemint was 10/20. Because the results now involve the same weight on the denominator, the results can now be fairly compared. Bubblicious still contained the largest amount of sugar. This type of gum was made up of 75% sugar. Bazooka contained the second largest amount of sugar. Falling just short of Bubblicious, this type of gum contained 70% sugar. Doublemint contained the least amount of sugar. It is made up of only 50% sugar. Because Bubblicious contains more sugar than Bazooka and Doublemint, it's flavor lasts longer. This is because the more sugar gum contains, the longer it takes for all of this white substance to dissolve. Therefore, the sweet take that comes from sugar remains in the gum for a longer time period. However, this did not apply to Bazooka and Doublemint. Although Doublemint contained the least amount of sugar out of the two gum types, the flavor of Doublemint lasted longer than Bazooka's bubble gum flavor. This is because of the artificial mint flavoring found in Wrigley's Doublemint gum. When performing this experiment, some mistakes were made. Often, the gum in each trial weren't chewed for the same amount of time. Bubblicious bubble gum was a good example of this. This gum's flavor lasted the longest, and in some of the ten trials, the gum was not chewed until the flavor was completely gone. This also applied to Doublemint. The results of the sugar test were most likely not affected by this, though, because many pieces of gum were chewed for more than an hour, and the weights were very similar. If this experiment was being performed again, a few changes should be made. First, the number of trials for each type of gum should be reduced from ten to four or five. It is very hard to chew ten pieces of Bubblicious bubble gum in a limited amount of time. If things had gone perfectly, one would have been chewing just Bubblicious for more than ten hours! Also, every piece of gum should be weighed an equal number of days after it was chewed. Some pieces were weighed the day after chewing, and others were weighed five days after chewing. This could have a major impact on the results of the experiment. All types of gum should be cut down to have the exact weight of the other two types of gum before the gum is chewed. This is to make the results of the experiment easy to compare without having to go through a complicated process after the experiment was performed to find out which type of gum contained the most sugar. Through the sugar test, it was discovered that Bubblicious contains the most amount of sugar, that some mistakes were made, and that some changes should be made to future sugar test experiments.
The next test performed was the stretch test. Like the sugar test, Bubblicious had the biggest stretch, but one cannot be sure of this because Bubblicious had the largest volume to begin with. In future experiments, each type of gum should be cut down to have the exact same weight in grams, because otherwise, the results may not be absolutely correct. If like the sugar test, the results of the stretch test are true before a step-by-step mathematical procedure is applied, then Bubblicious stretched the furthest, Doublemint the second furthest, and Bazooka the least. Although one can't be positive that Bubblicious had the largest stretch, he can be sure that Doublemint stretched more than Bazooka. This is because Doublemint has a smaller volume than Bazooka to begin with. Doublemint stretched further than Bazooka because of the visco-elasticity in the two different types of gum. The base of Doublemint gum contains more visco-elasticity than the base of Bazooka bubble gum. This allows the gum to stretch more when saliva becomes intertwined within the many molecules. One eye-catching mistake was made during this experiment. Before the experiment was performed, no part of the procedure stated when to stop stretching the gum. Some pieces of gum were stretched until they nearly broke, while other pieces were stretched until the piece had a thin, even width. This is why the gum in the trials for Bubblicious had a wide variety of lengths. In a future experiment it would be wise to have an exact width that all pieces must reach. It is an almost positive fact that Bubblicious had the biggest stretch, that some mistakes were made, and that improvements can be made to make this experiment better.

Multiple pieces of data were obtained in the volume test that was conducted. This test measured the volumes of bubbles blown by three different types of gum. The volumes were obtained by measuring the diameter in centimeters from the mouth to the end of the bubble. This provided data for volumes to found. The procedure had small amount of constants, including the object being formed (a bubble) and what was being consumed (gum). To convert the diameter into volume a formula had to be applied. Since bubbles are spheres the formula for a sphere can be applied: 4/3(pi)(radius cubed). This formula provided the volumes of each bubble for each gum. This data clearly shows that Bubblicious blows the bubbles with the largest bubbles, since it had a average volume of 178.3 centimeters cubed compared to Bazooka with 35.4 centimeters cubed and 9.5 centimeters cubed for Doublemint. The reason that this experiment concluded that Bubblicious blew that largest bubbles is most likely because of a flaw in the procedure. The pieces of gum should have been sized equally instead of leaving the sizes as they were, since Bubblicious had the largest volume before chewing. This difference in size most likely caused Bubblicious to have more volume because it had more volume initially. There was another flaw in the procedure. By using one piece of gum for multiple bubbles there were many things not kept constant. Therefore the data is not valid if the constants are not kept in place. Bubblicious blew the largest sized bubbles because it was kept larger initially.

If a customer is seeking to buy Bubble gum of any flavor, it would be best to buy Bubblicious. Is is a known fact that Bubblicious contains more sugar than Bazooka and Doublemint gum. Therefore, it's flavor is very long lasting. One can be almost positive that Bubblicious has the biggest stretch. This is good because a larger stretch makes the gum easy to chew. Also, Bubblicious allows one to blow bubbles of a large volume. This makes the gum more fun to chew. Through this experiment, one can conclude that Bubblicious is the best type of gum to chew.
