Diet Coke and Mentos

Background Introduction and Hypothesis
The Mentos and Diet Coke Experience has become quite popular all around the
United States. When Mentos are dropped in Diet Coke, a huge eruption occurs. The
main idea of this experience is to determine what causes the interesting reaction.
There are many different theories floating around the internet, however; only one
can be correct. This lab requires performing the Mentos and Diet Coke experiment
numerous times, changing a variable. The variable that is going to be tested and
changed is the substance Gum Arabic- an ingredient in the Mentos. The ingredient
Gum Arabic reacts with the carbonation of the soda – making the huge eruption.

Abstract
Our goal for the experiment was to find if the ingredient
“Gum Arabic”, found in Mentos candy, caused the
eruption when Mentos were dropped into a bottle of Diet
Coke. Our hypothesis was that candies with gum arabic
would have a greater reaction than those that did not.
We tested this by dropping Mentos, Tic-Tacs, SweeTarts,
and Kit-Kats into 2-liter bottles of diet coke, and
measuring how much was left in the bottle when the
reaction was done. Our hypothesis was proved incorrect
by our experiment, because the second most-reactive
candy was SweeTarts, which does not contain Gum
Arabic.
Conclusion
After doing the experiment, it was decided that the hypothesis was to be rejected. The
hypothesis stated that the gum Arabic from the Mentos, and the carbonation from the Diet
Coke created the reaction. However, two of the four candies used in the experiment did not
contain gum Arabic, and they had extreme reactions. For instance, the Sweetarts
(containing no gum Arabic) and Diet Coke mixture had the highest fizz geyser and only had
32 oz. of the solution left after the reaction. Obviously, this proved our hypothesis wrong.
From this experiment, the group learned that this reaction is not a chemical, but a physical
reaction. After this information was obtained, the group discovered that it cannot be the
gum Arabic causing the reaction because all the candies created fizz and geysers. This
showed that Mentos are not the only candy that can react with the Diet Coke. The
experiment showed the group that candy and Diet Coke can potentially be dangerous. If
someone takes a sip of Diet Coke directly after putting a piece of candy in their mouth, the
reaction could occur inside their mouth. Aside from that, the errors in the experiment
should be discussed. One possible error that was made was when the Tic-Tacs were
dropped in the funnel, not all of them went through. This could have affected the results of
the experiment. So, if the experiment was done again, the size of the funnel should be
modified. Overall, the experiment went very smoothly and the results were quite surprising.
