Coke Combined with Mentos Lab

Guiding Question: How does the flavor of mantoes affect the reaction it has with Coke Zero?

Hypothesis: Fruit mantoes will be less reactive than others, they will just froth and foam. Whereas i think the coke will be slightly reactive. And then the mint very reactive.

Materials:  

- 1 Coke Zero Bottle

- Fruit Mantos

- Mint Mantos

- Granulated Cylinder

- Goggles

Process:

1. Pour 50 ml of Coke Zero into the gradulated cylinder.

2. Drop 1 fruit mentos in and observe the reaction.

3. In a different cylinder filed with 50 ml of Coke Zero, drop 1 mint mentos.

4. Do this for every flavor of mentos.

5. Observe the reaction in each case.

6. Create data table of reactions.

7. Draw conclusions and further inquiry.

Data Table:

Materials	Predictions	Observations Before Reaction	Observations During Reaction	Observations After Reaction
Mint Mentos + Coke Zero	A lot of fizzing up probably biggest reaction	1 Mentos and 50 ml coke zero	Fizzed for a long time. However didn’t bubble up very high in the cylinder.	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Mint Mentos + Coke Zero	I think that there will be a bigger reaction than the whole mint mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	basically same reaction but happened faster and mentos didn’t sink to bottom stayed floating on top.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Grape  Mentos + Coke Zero	I think they are going to have a similar reaction to the other fruit flavors quite a lot of fizzing but not as much as the mint mentos are going to have.	1 Mentos and 50 ml coke zero	Fizzes up to 60 ml on the cylinder and then goes back to 53. happens very quickly.	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Grape Mentos + Coke Zero	I think that there will be a bigger reaction than the whole grape mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	hardly any reaction	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Strawberry Mentos + Coke Zero	I think that this reaction will be very strong because the strawberry mentos is very sweet.	1 Mentos and 50 ml coke zero	nothing much of a reaction. Fizzes a small amount	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Strawberry Mentos + Coke Zero	I think that there will be a bigger reaction than the whole strawberry mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	fizzes a lot more than the other one. quite a largre reaction. we found this very surpirsing.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Orange Mentos + Coke Zero	I’m not sure what will happen with the orange mentos, probably a medium reaction.	1 Mentos and 50 ml coke zero	barely anything happens	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Orange Mentos + Coke Zero	I think that there will be a bigger reaction than the whole orange mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	nothing happened they just stayed at the top and coke bubbled slightly.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Watermelon Mentos + Coke Zero	The watermelon mentos is very sweet so I think it will make a big reaction.	1 Mentos and 50 ml coke zero	Fizzed for a long time. However didn’t bubble up very high in the cylinder.	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Watermelon Mentos + Coke Zero	I think that there will be a bigger reaction than the whole watermelon mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	fizzed for a long time same thing as non crushed happened.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Pineapple Mentos + Coke Zero	I don’t realy know what will happen to the pineapple mentos as it is not as sweet as the others. It’s more bitter. Maybe this will affect the reaction.	1 Mentos and 50 ml coke zero	very quickly starts fizzing (quicker than the others) but not a lot of bubbling up.	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Pineapple Mentos + Coke Zero	I think that there will be a bigger reaction than the whole pineapple mentos because it is powder and it will dilute/ dissolve  in the coke.	1 crushed mentos and 50 ml coke zero	A lot of fizzing happened. but the coke had been sitting out for a while so it had losts most of its bubbles.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Raspberry Mentos + Coke Zero	I think that the reaction will be less reactive than watermelon but still very big because raspberry mentos are very sweet.	1 Mentos and 50 ml coke zero	Most reactive out of all (including mint) reacts quickly and over flows stays overflowing for a while!	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Raspberry Mentos + Coke Zero	I think that there will be a bigger reaction than the whole raspberry mentos because it is powder and it will dilute/ dissolve in the coke.	1 crushed mentos and 50 ml coke zero	Again along with the green apples it had one of the biggest reactions	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.
Green Apple Mentos + Coke Zero	I think that there will be a big reaction because there is a lot of sugar in the green apple mentos.	1 Mentos and 50 ml coke zero.	Nothing really happens about the same reaction as the orange.	mentos sunk to the bottom and stayed there. While coke went back to its original state.
Crushed Green Apple Mentos + Coke Zero	I think that there will be a bigger reaction than the whole apple mentos because it is powder and it will dilute/dissolve in the coke.	1 crushed mentos and 50 ml coke zero.	It happend about the same as the crushed rasberry mentos.	For the crushed mentos the coke remained looking slightly foamed at the top while the crushed pieces reacted and then sunk to the bottom of the measuring cylinder.

Data Analysis (Emily): As it turns out our predictions were correct, the crushed mentos would reacts quicker with a larger reaction compared to the whole mentos. We realized when each reaction was over when the coke stopped bubbling and the mentos began sinking to the bottom (this is for crushed). As for the whole mentos you knew when it was over because the coke which rose slightly during the reaction would then return to its original state of 50ml. I also noticed that the state of the coke changed slightly becoming more diluted. also the mentos color had completely faded away leaving them a light whitish cream color.

Conclusion (Emily): How does the flavor of mantoes affect the reaction it has with Coke Zero? What seems to have the largest effect is the fruit mentos especially the more sugar filled ones (such as the raspberry). Once the reaction was over there was no new substances made they only returned to they’re original chemical state but their physical state was different (for example the color of the mentos). However the chemicals and sugar in the coke and mentos that caused the reaction did eventually exhaust themselves thus bringing the reaction to an end so i guess some of the chemical properties changed but not enough to make a new substance.

Further Inquiry (Emily): I think that one of the ways our data could have been more accurate is if we hadn’t left the coke sitting open for so long which gave it time to distill causing less of a reaction than we could have had. Also if we had timed how long the reaction would have gone on we could have managed to judge better which flavors worked better. Because if you look at our data table you can tell that some of the reactions were almost identical which would mean it would be easier to judge which was larger/which was smaller.
