Mentos and Soda Test

Abstract

Which Soda Produces the Most Amount of Fizz?

`

For my science fair project, I wanted to experiment which type of soda produces the most amount of fizz when Mentos mint candies added to them. The sodas I chose to experiment on were Mountain Dew, Orange Fanta, Original Coca-Cola, and Diet Coke. My hypothesis was that Mountain Dew would produce the most amount of fizz because of its large amount of sugar.

To start the improved version of the experiment, I set down a tarp on the ground to keep messes of soda off of the floor. Also, I put the soda in the same storage container. Then, I placed one soda at a time in the container. Once the soda was ready in the container and my phone was recording, I inserted one Mento. After that, I watched the fizz go up and down. Once the fizz was gone, I took the Mento out of the bottle and poured the remainder of the soda into a graduated cylinder. Lastly, I measured the amount of soda left, poured the soda out and started again.

The first soda I experimented on was Orange Fanta. The average of soda left in the Orange Fanta bottle was 464 mL. Next, I tested Mountain Dew and no soda came out, therefore I was left with 500 mL. Coca-Cola’s amount left was an average of 308 mL. The last soda I tested was Diet Coke. Diet Coke’s reaction was the biggest and an average of only 275 mL was left in the bottle.

To conclude, Diet Coke produced the greatest amount of fizz, followed by Coca-Cola, Orange Fanta and Mountain Dew. While doing this project, I learned which soda created the most fizz and why. My hypothesis was the exact opposite of correct. Mountain Dew, the soda that I hypothesized would make the most, made the smallest reaction. Mountain Dew’s reaction did not come out of the bottle. Instead, Diet Coke had the biggest reaction. Possible sources of error would be the measurement. But, my experiment was accurate because I tested each soda six times and measured them using the same graduated cylinder. Ways I could improve this experiment would be adding more items to test. Different flavors of soda could have been used or even different types of mentos. Also I could have used different sized sodas and more mentos.

Conclusion

To conclude, Diet Coke created the highest amount of fizz. After Diet Coke, Coca-Cola, Fanta and Mountain Dew followed. My hypothesis did not agree with this data. Instead of Mountain Dew creating the most amount of fizz, it actually created so little that it could not come out of the bottle. I think that my experiment was accurate because I repeated it six separate times. If I were to experiment this again, I would use different flavors of sodas and/or different flavors of Mentos.
