What is the science behind the Mentos and Coke experiment?

What is the science behind the Mentos and Coke experiment?

Bubbles and soda will quickly shoot out of the bottle in a high fountain. The carbon dioxide molecules attach to the surfaces of the Mentos like they did in the cup of soda. All those Mentos in a lot of soda make a lot of bubbles that rise to the surface and push the soda out in a big woosh!

What is the independent variable in the Mentos and Diet Coke experiment?

The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response.

Does the amount of Mentos affect the height of the explosion?

Analysis: This graph does a good job revealing the relationship between the number of Mentos put in a Coke and the height which the geyser will reach. At first when a Mento is added, it affects the results dramatically. As the number of Mentos grew, the impact of each additional Mento decreased.

Is Coke and Mentos a physical or chemical change?

physical change
Mixing Coke and Mentos looks like a chemical change, but since the gas released is carbon dioxide AND it was present before the foaming happened, it is actually a physical change.

Is Diet Coke and Mentos a chemical or physical change?

physical reaction
After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. Their explanation is this process called nucleation. All the carbon dioxide in the soda – all that fizz – is squeezed into the liquid and looking for a way out.

Why is Coke and Mentos a physical change?

Coke and Mentos. Mixing Coke and Mentos looks like a chemical change, but since the gas released is carbon dioxide AND it was present before the foaming happened, it is actually a physical change.

Why does Diet Coke work the best with Mentos?

Why does Diet Coke work best with Mentos? Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water.

What causes the reaction between Mentos and Diet Coke?

Wax paper

  • Cutting board
  • Knife
  • One roll of Mentos (at least eight candies)
  • Two index cards
  • Tape
  • Two two-liter bottles of Diet Coke
  • An outdoor area at least two meters from buildings
  • Eye protection (safety goggles or glasses)
  • Video camera with either a tripod or a helper to take the images (optional) Preparation
  • How did Diet Coke and Mentos become so popular?

    The formation of the incredible foaming action is accomplished through the combination of the carbon dioxide gas, the aspartame and the potassium benzoate in the Diet Coke when combined with the gum arabic ingredients and gelatin of the Mentos. The Mentos is the perfect addition to the mixture due to its surface.

    Do you have to use Diet Coke With Mentos?

    Use more Mentos for a bigger geyser. If you can drop a few in very quickly, your eruption will be larger than one with a single candy. Use bottles of various sizes to see different sizes of geysers. You don’t have to use Diet Coke! Any soda will do.
