conclusion for coke and mentos experiment

As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption. The images were acquired with a beam energy of 12.5kV and a spot size of 5.0nm. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle's base. All the carbon dioxide in the soda all that fizz is squeezed into the liquid and looking for a way out. https://www.scientificamerican.com/article/bring-science-home-coke-mentos/. [1], Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. To add insult to injury, she did it two more times. Pepper has the strongest reaction. Follow our step-by-step instructions in our Mentos Geyser Experiment to find out. Explore the science of building polymers by cross-linking long chains of molecules. (Gruber, 2019). Does the amount of Mentos affect the height of the explosion? The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. Because Type IV nucleation sites (such as found on Mentos) allow the reaction to proceed with substantially lower activation energy, Mentos candies can appropriately be considered a catalyst of the process. We used a FEI Quanta 200 electron scanning microscope. Youve probably heard that you shouldnt eat Mentos while you drink Coke, but why is that? Hall, Jonathan Hearing, Leander Hutton, Kelly Izlar, Cully Little, James Lugenbell, Michael Mace, Bonnie Myers, Carla Penders, Zach Russell, Shane Shields, Adrian Steffen, Tony Sturtzel, and Zach Yokley. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. Note be sure to only try this experiment with a responsible adult! Mentos Lab Report - Google Docs Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. With 5 or 6 mentos the explosion went only 330 and 310 cm high. Muir, H. (2008, June 12). Hopefully, this article can help you finally place a scientific explanation behind this iconic and messy science experiment. [Full Guide]. This is what happens when you combine 200 liters of Diet Coke and over 500 Mentos mints! This hypothesis was also proven false as the pH of the substance did not change after the reaction (Muir, 2008). The average times were 0.7s for the Mentos, 1.0s for the rock salt and the Lifesavers, and 1.5s for the sand. Diet Coke and Mentos: What is really behind this physical reaction Does one brand produce higher geysers? We found that the Diet CokeMint Mentos reaction lasted 3.8s, the Diet CokeFruit Mentos reaction lasted 3.6s, and the Diet CokeWint-o-Green reaction lasted 4.9s. What did you observe when you put Mentos candy into the soda bottle? Can I use clear bottom plates for fluorescence? The blend of Coke Zero and Mentos just works out the strongest. Mentos candies contain millions of cavities, roughly 1-3 m in size,[25][10] that remain unwetted when added to a soda. height These growth sites are not all on the surface of the bead, and hence the Diet Coke has to soak into the bead through the pores. Also, the coating dissolves very rapidly in water, and so is not effective at preventing the growth of carbon dioxide bubbles. Well, its probably not pretty. You can also place the bottle of unopened soda in a bucket of warm water. The carbon dioxide attaches throughout the bead, increasing the amount of time over which the reaction occurs. And its a great way to learn about chemical reactions. All of the samples were at room temperature unless otherwise indicated. St. Helens and Mt. The video was titled Extreme Diet Coke & Mentos Experiments. So, Im going to go with Mentos. They cited the gum arabic and gelatin in the Mentos, and the caffeine, potassium benzoate, and aspartame in Diet Coke as the main contributors to the explosive reaction. Coke has a pH of 2.3 and it made intuitive sense that an acid-base reaction could explain the sudden explosion of sugar. Tobin, Declan. Is the coke and Mentos reaction really a chemical reaction? [16] In October 2010, a Guinness World Record of 2,865 simultaneous geysers was set at an event organized by Perfetti Van Melle at the SM Mall of Asia Complex, in Manila, Philippines. Some helpful comments were made by the anonymous referees. It is an excellent way for children to see gas in action and is a great activity to teach For that reason, I solicited help from our creative team at Steve Spangler Science to come up with a Geyser Tube a better, more consistent way to drop the Mentos candies into the 2-liter bottle. As the liquid is heated, the gas within that liquid is also heated, causing the gas molecules to move faster and faster. Write down what happened when you dropped the Mentos in the coke. The experiment became a subject of the television show MythBusters in 2006. Diet Coke and Mentos: Testing New Variables WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. Regular Coke does not work with Mentos because the Diet Coke uses Aspartame instead of sugar, which regular Coke uses. Fueled by hundreds of blogs and popular online sharing sites like YouTube, this once obscure reaction quickly became a sensational hands-on learning activity for young scientists. Does the amount of Mentos affect the height of the explosion? Their surfactant properties then lower the surface tension of the Coke, which breaks apart the water molecules and, in doing so, allows carbon dioxide bubbles to form more readily. Superabsorbent giant growing polymer beads that absorb 150 times their weight in water! . What exactly happens when you mix Mentos and Coke? Once the geyser stops, measure how much liquid is left inside. [15] Amazing Toys, Spangler's toy company, released the Geyser Tube toys in February 2007. In this experiment, you will evaluate whether or not a diet that is supplemented with "brain-enhancing" foods can help improve memory. Alternatively, dispense the soda into a vase or pitcher. It is clear from Table V that the roughness of the sample is a major contributor to the explosiveness of the reaction. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. The Diet Coke and Mentos reaction is a popular experiment or demonstration in part because it inspires students to wonder, and inquiry-driven labs and active-learning demonstrations on this reaction have been implemented. Its also a lot less work than your classic paper mache volcano. Does warm Diet Coke create a greater geyser explosion than cold Diet Coke does? Conclusion - Diet Coke and Mentos 100 - Google Sites The Diet Cokeliquid gum arabic and Diet CokeDawn/water mixture trials demonstrate that even without any surface roughness, the introduction of a surfactant into the soda causes a reaction. The physical characteristics of Mentos (surface roughness) have the effect of drastically reducing the activation energy for carbon dioxide bubble formation so that the nucleation rate becomes exceedingly high. Grobe, F., & Voltz, S. The Science of Coke and Mentos. The answer is a process called nucleation (Grobe & Voltz, n.d.). Science Fair Project: The Diet Coke and Mentos Explosion
