This lab was to find out which brand gum, between Hubba Bubba and Big League Chew, could produce the biggest bubbles and how the different products stretched. Both gums weighed 7.9 grams. Hubba Bubba was Gum A and Big League Chew was Gum B. Gum A was purple and had a thick density. It was in the shape of a tightly packed block and was very sturdy. Gum B was pink and stringy. It was very thin and flexible. We came up with a hypothesis for the two gums bubble creating ability. If Hubba Bubba is blown into a bubble, then it will be larger than Big League Chew because Hubba Bubba has a stronger consistency and won’t break as easily as it grows.  

Our material was as follows; Hubba Bubba, Big League Chew, 1 metre stick, and 2 pieces of tin foil.

The lab began with one of us chewing the gum for 3 minutes, then blowing bubbles 5 times and measuring them to find the average. We did the exact same procedure for the next gum.

Gum A	Circumfrence
1	16 cm
2	21 cm
3	12 cm
4	14 cm
5	25 cm

Gum B	Circumfrence
1	6 cm
2	19 cm
3	14 cm
4	8 cm
5	11 cm

After taking all the measurements we found the average of Gum A was 17.6 cm in circumference and Gum B had 11.6 cm in circumference.

We could then conclude that Hubba Bubba is the gum best for blowing bubbles between the two. This is because the gum was much thicker and harder to chew in the mouth; when blown, it had a thicker consistency and could stretch farther and not break.

Part 2, we tested how far each gum could stretch and how that related to its bubble size. If the gum was able to create big bubbles, then it should also stretch further because it is strong enough to stretch and not break. 

We took the pieces of tin foil, stuck two ends of the gum to them, and pulled. With one trial we found that Gum A had the length of 46.1 cm and Gum B got to 82 cm.

We could then conclude that our hypothesis was incorrect. If a piece of gum has a bigger bubble size than another brand, this does not mean the stretchability is larger as well. If it blows a bigger bubble it is because the strength of the consistency is able to hold much more air. The more thin and stringier the gum, the further it should be able to stretch. This data showed that the Big League Chew was stringier, with a softer consistency. Hubba Bubba had a strong consistency that let it be blown huge, but couldn’t stretch as far when pulled.

We also recognized that there could have been some factors that could’ve affected the outcome of this experiment.

1. The ability to blow bubbles. The bubble blowers experience in chewing and blowing bubbles.
2. The length that the gum was chewed.
3. Whether or not the gum was chewed recently or it waited a while and got dry.
4. The chewers chew and the strength of their chew. The level of softness they got it to.
5. The saliva of the chewer.

To finally conclude, after observing both experiments and seeing the results, our hypothesis should be refuted. Even though the first hypothesis was proven correct, the second one was proven wrong. For both these experiments, the factors listed above could’ve definitely played a role in the success of finding an accurate resolution. From what witnessed with our experiment, the gum stretchability was different when being blown into and being pulled. I think this is because of how long Gum A waited until it was pulled. When we went to pull Gum A, it was super dry and stuck together closely. This could be an explanation for why Gum B was able to be pulled so much farther, it was still soft from freshly being chewed. The results of this experiment were not accurate, we had many factors that were changing the results and the variables. We should have waited the same amount of time before pulling Gum B as we did Gum A. In the end, we did learn that every part of an experiment matters to the results and that we were able to blow bigger bubbles with Hubba Bubba and not have it break.
