Mentos and Coke
Materials-12 Fl Oz coke, mint mentos, and thermometer
Purpose-What I wanted to find out is if the temperature affects how the mento bubbles in the coke.
Procedure-How I tested my project was to put two 12 Fl Oz cokes one on the counter at room temperature (69 F)and one in the fridge(40 F).Then after 24 hours I took one mento and dropped it in the one that was on the counter at room temperature and timed and examined how it bubbled. Then I got out the coke in the fridge and took one mento, dropped it in and timed and examined how it bubbled.
For the 2nd test I had two 12 Fl Oz cokes (same as the other test)But for this test the cokes were opened. One on the counter at room temperature(69 F) and one in the fridge(40 F). And like the last test I waited for 24 hours to pass and then when it became time to test I took them out and I dropped in 1 mento in the room temperature one(69 F) and timed and examined how it bubbled and then I did the same with the one in the fridge(40 F). Then I recorded my data.
Discussion-Two things that could of or did go wrong is that the coke could have been old and was flat which could of affected the mento and how it bubbled. Also the mentos could have been old or stale which could of affected the coke.
Conclusion-Two things I learned is that the room temperature one at 69 F bubbled for 22 seconds and lost 6 Fl Oz but the colder one or the one in the fridge only lost 2.5 Fl Oz. Also with the opened cokes the room temperature lost 6 Fl Oz too but the colder one or the fridge one at 40 F only lost 1 Fl Oz. So that shows that a coke at room temperature bubbles a lot more then a coke in the fridge.
