conclusion for coke and mentos experiment

While I had performed variations of the Mentos Geyser Experiment on television many times from 2001 to 2004, my performance of the demo in the backyard of Denvers NBC affiliate KUSA-TV in September of 2005 proved to be the tipping point. Diet Coke 280 8.6 Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. However, the larger rock salt pellets fall quickly to the bottom of the 2l bottle, while the much smaller table salt grains fall more slowly due to their smaller weight and size. The reaction happens fast, so dont have your face over the bottle. What effect does temperature have on the height of the geyser? Well even provide all the seeds and dirt you need for your exploration into the world of plants. How many protons and electrons are present in Ba2+? CYSF Due to the popularity of the Diet CokeMentos reaction as a demonstration of key principles in physics and chemistry, we have investigated the causes of the reaction. Making science accessible and fun for youth. [1][14][17] Tonya Coffey, a physicist at Appalachian State University, suggested that aspartame in diet drinks lowers the surface tension in the water and causes a bigger reaction, but that caffeine does not accelerate the process. No matter which brand of soda you tested, the warm bottle probably produced the highest shooting geyser. In a sealed bottle of soda pop, the gas above the liquid in the bottle has a high partial pressure of carbon dioxide compared to the air we breathe. Mentos The AFM rms roughness measurements are given in Table V. The SEM images of some of the samples are shown in Figs. The colorful nature of this chemistry experiment kit introduces your child to basic concepts of volume, measurement and chemical reactions in a safe, no-mess way. You want the bottle to be stable before conducting the experiment. Fortunately, the maker of Mentos (Perfetti Van Melle) also liked our Geyser Tube design. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. [30] However, any carbonated beverage will work. Why does the coke react to Mentos? Average horizontal distance traveled by the spray during the reaction. However, you wont get the same effect from eating Mentos after drinking Coke. Learn all about the secrets that make seeds grow and the conservation power of Water Jelly Crystals. Their explanation is this process called nucleation. Discover how science and magic have always been connected! Mentos Its time to return to your launching site. Thanks also to Guichuan Hou and Phil Russell for their help in acquiring the SEM images, and to Donovan Leonard for his help in acquiring some of the AFM images. When you pull your finger out of the way, all seven Mentos should fall into the bottle at the same time. This demonstration illustrates many important ideas in physics, including key principles in thermodynamics, surface science, and the physics of eruptions. Team students up and have them collaborate to figure out chemistry experiments or give your own kids a fun, rainy day activity that will get them excited about learning. In conclusion the hypothesis that the diet coke will have the greatest explosion because of the high level of CO2 gas contained in it was correct. Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. The seltzer and tonic water were not Coca-Cola products, and it was not possible to find seltzer and tonic water with the same expiration date as the Coke products. The video was titled Extreme Diet Coke & Mentos Experiments. In colder liquids, the gas molecules move very slowly, causing them to diffuse out of the solution much more slowly, leaving more gas in the solution. Your kid may be surprised to learn that the density of coke and diet coke aren't the same! Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual. Mentos Geyser Experiment - Mentos & Coke Experiment - The Lab Put the index card on top of the tube loader and turn the tube upside down. Turns out that diet coke, which gets its sweetness from artificial sweeteners such as aspartame, is more commonly used than its regular counterpart. This work was supported in part by the College of Arts and Sciences at Appalachian State University, the Petroleum Research Fund, Grant No PRF# 44936-GB5, and an NC Space Grant, New Investigations Award. Mentos are heavy and can travel the entire volume of the bottle, breaking many bonds and building a lot of pressure that is released in the form of a geyser of soda (Grobe & Voltz, n.d.). Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. However, the brightly colored Mentos the Mythbusters dropped into the soda had a waxy coating added by the Mythbusters team, not the Mentos manufacturers.1. Turn from eerie green to blood red when you hold it up to the light. Mentos Experiment Observe the eruptionheight, trajectory, duration, etc. This science kit seeks to challenge kids to solve problems in creative ways that will prepare them for future science classes and nurture their lifelong imagination. Contact angles of various solutions on polycarbonate and the ratio of the minimum work required to form a critical bubble in the sample over the minimum work required to form a critical bubble in deionized H2O. What is the fastest way to level up pickpocketing in Skyrim? Conclusion. How does the flavor of Mentos affect the explosion? https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. Next, some thought that the pH of the liquid was responsible for the vigorous reaction. They also hypothesized that the rough surface of the Mentos can help break the strong polar attraction that water molecules have for each other by providing growth sites for the carbon dioxide, agreeing with scientists such as Lee Marek and Steve Spangler.2 Although they identified the prime ingredients, they did not sufficiently explain why those ingredients affect the explosion, nor did they provide direct proof of the roughness of the Mentosa tall order for an hour-long television program. These ready-made bubbles (which are nucleation sites) exist in things such as tiny fibers or non-wettable crevices on the sides of the bottle. The blend of Coke Zero and Mentos just works out the strongest. Observe and explain the Mentos and Diet Coke experiment. Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle. Within seconds of dropping the candies into the soda, a huge geyser would erupt from the bottle. Carbonated beverages are full of dissolved carbon dioxide gas (CO2) which makes bonds with the water molecules. In addition to the six outlined experiments, weve included suggestions for further fun, giving your future chemist more opportunities to learn and grow. Science project. [10][23][24] Because there usually are very few such pre-existing bubbles, the degassing process is slow. (Compare the volcanic explosions of Mt. As soon as the Mentos hit the soda, bubbles cling to the surfaces of the candies and then quickly rise to the surface of the liquid. First, we learned that the massive buildup of pressure occurs when carbonation causes bubbles to accumulate on the surface of the Mentos. Record the temperature. All of the Coca-Cola products had the same expiration date, so the level of carbonation in each 2l bottle should be similar. SEM images of playground sand acquired at a beam energy of 20kV and a spot size of 5.0nm. The activation energy for the release of carbon dioxide from Diet Coke by the addition of Mentos is 25 kJ mol1. You can also use a Baby Soda Bottle to hold the Mentos or a Geyser Tube, which was invented to solve this very problem. [27][28] Thus, the geyser reaction will still work even using sugared drinks, but diet is commonly used both for the sake of a larger geyser as well as to avoid having to clean up the stickier residue left by a sugared soda. Language links are at the top of the page across from the title. The Mythbusters correctly identified potassium benzoate and aspartame as key ingredients in the Diet CokeMentos reaction. Retrieved from https://easyscienceforkids.com/diet-coke-and-mentos-video-for-kids/. What factors made dabbawala system successful? [25] These results suggest that additives serve to enhance geyser heights not by decreasing surface tension, but rather by decreasing bubble coalescence. This science demonstration was popular among chemistry teachers back in the 1980s. These tiny pits act as nucleation sites, which are perfect for carbon dioxide bubbles. It really only takes a few minutes to setup the mentos and coke volcano experiment. 2008 American Association of Physics Teachers. The diet coke erupted like a volcano. This chemistry science kit includes activities for solo and group experiments, making it a fantastic addition to your classroom or for fun at home. CYSF WebCONCLUSIONS: ( Do you accept or reject your hypothesis, and why or why not) You and your partner will share your experiment with the class. When they are dropped into the soda, these sharp edges break the bonds between the dissolved gas and water, allowing for the gas to turn into bubbles and escape (Science Buddies, 2012). Write down what happened when you dropped the Mentos in the coke. Native American Teepees, Longhouses, Pueblos, Nebraska State History US History Facts, Becoming a US Citizen US Government Facts, 12 Michael Jackson Facts For Kids 2023 [Must Read], Mood in Literature (Definition, Examples & Case Studies) 2023, Antithesis Examples, Definition, Usage, and Popular instances. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. Muir, H. (2008, June 12). Fast-moving mentos create larger explosions while slow, powdered mentos create tiny ones (Muir, 2008). The longer reaction time is due to the many growth sites associated with the porous molecular sieve beads. In addition to the six outlined experiments, weve included suggestions for further fun, giving your future chemist more opportunities to learn and grow. It is the classic Diet Coke and Mentos "geyser" experiment, but with the added rigor of using the scientific method to answer the question "Which will cause a larger reaction: the sugar in regular Coke or the aspartame in Diet Coke?" [12] The work required to form a bubble in sugar water and aspartame is 74% and 67%, respectively, of the work required to form a bubble in pure water. Be sure that the soda bottles are all the same brand and type. 4). 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. Does Colorado have a defensive driving course? A more dramatic effect is the rate of the reaction. eleanorrigby-movie.com 2023 Enough mass was deposited by the Hawaiian hot spot to form the islands, but the eruptions were comparatively gentle.) Experiment with your sense of taste and your sense of smell with this simple experiment! The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle. Because Mentos mints didnt have holes in the middle like LifeSavers, getting them into the bottle was a little tricky. Retrieved January 31, 2021, from https://www.bravotv.com/top-chef/blogs/diet-coke-takes-longer-for-flight-attendants-to-serve-on-airplanes-bubbles#:~:text=Sugar%20both%20increases%20viscosity%20and,bubbles%20that%20pop%20much%20slower.%22&text=In%20the%20end%2C%20the%20total,out%20by%20a%20few%20seconds. Because of this, the addition of Mentos candies to a carbonated beverage provides enormous numbers of pre-existing bubbles into which dissolved carbon dioxide can escape. When the gum arabic was injected at the bottom of the bottle, 100g of mass was lost. How does the temperature of the soda affect the height of the soda stream when Mentos are added to soda? The variable could be something like the number of mentos dropped into the bottle, the flavor of diet soda, the size of the bottle, or the temperature of the soda. The reaction has been performed numerous times on television and the Internet, but has not been systematically studied. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. In this project, you'll create Oersted's experiment, which relates to how electric currents create magnetic fields. We used a video camera to measure the time it took for Mentos, rock salt, Wint-o-Green Lifesavers, and playground sand to fall through water from the top of the water line to the bottom of a clear 2l bottle. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. What is the independent variable in the Mentos experiment? Science of Mentos-Diet Coke explosions explained. Coke And Mentos Experiment Free Essay Example - PaperAp.com Under these conditions, carbon dioxide begins to degas from the solution, forming gas bubbles. What female country singers were on American Idol? Using any more than seven Mentos mints is just a waste, according to these soda-soaked science enthusiasts. The answer is a little more complicated than you might think. In Eq. The participant got it right for $8,000, saying: I saw it on TV, and I bought Mentos and a 2-liter bottle of Diet Coke. To maintain consistency we also constructed a tube to fit over the mouth of the bottle and a delivery mechanism for the solid materials. Does the amount of Mentos affect the height of the explosion? Hall, Magdalena Jaramillo, Cully Little, and Zach Russell, and my graduate research assistant, Jon Jones. Steve Spanglers Geyser Tube toy (optional . Pepper has the strongest reaction. As long as there is a high surface area to volume ratio, that area can be classified as a nucleation site (Grobe & Voltz, n.d.). Coke has a pH of 2.3 and it made intuitive sense that an acid-base reaction could explain the sudden explosion of sugar. WebFun Science Experiments // Mentos and Coke / Soda ExperimentIncludes BOTH US size and Australian A4 sized files/spelling!This fun experiment explores the physical reaction between mentos and diet coke / diet soda creating an impressive geyser of carbon dioxide. The uncertainty is approximately 10%. So, Im going to go with Mentos. Many soda geyser-ologists believe that seven Mentos candies produce the highest shooting geyser. It comes with six fun experiments, a test tube rack, fizzing tablet and vegetable oil chemicals to play around with. The Mentos candy gelatin and gum arabic create an energy that breaks the surface tension of the soda. 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. For the reaction between Diet Coke and the molecular sieve beads, the lower limit on the duration of this reaction was 12s, a much longer time than all of the other reactions. Children will enjoy this hilarious story and use their hands to mix up a batch of Instant Worms. Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. The seltzer water and tonic water trials were 1l bottles with 16g of Mint Mentos added; all other trials were 30g of solid material added to a 2l bottle of liquid. You want the candies going in the bottle and not falling over the side. It is difficult to find beverages containing aspartame that do not contain a preservative such as potassium benzoate. Drop the Mentos into the diet soda. Gruber, B. Start by opening the cold bottle and dipping the thermometer into the soda. How Does Diet Affect Your Body Temperature? Bookmark this to easily find it later. Buddies, S. (2012, June 14). Mentos-Diet Coke Explosions Explained Bubble nucleation and growth in carbonated beverages almost always occur by heterogeneous nucleation: diffusion of carbon dioxide into pre-existing bubbles within the beverage. With everything you need to set up your own science lab anywhere, the Amazing Scientist Chemistry Kit is a fantastic introduction to the world of science. Set up three tests: warm soda, room temperature soda and cold soda. Quantitative Observation Does the amount of Mentos affect the height of the explosion? What causes the explosion when Mentos are dropped into the Diet Coke? Team students up and have them collaborate to figure out chemistry experiments or give your own kids a fun, rainy day activity that will get them excited about learning. Stir up some enthusiasm for experimentation with this candy-cracking science experiment! Although this conclusion seems to refute the claims made by the Mythbusters, remember that in their experiments, Jamie added enough caffeine to kill you to the seltzer water. normal, unaltered Mento. What is inside Mentos and Cola that reacts with each other causing the eruption? Within the next 12 months, over 800 Mentos Geyser Experiment-related videos were posted on YouTube, making the demo one of the most popular pop-culture science experiments in recent history. In this case, were changing the number of Mentos dropped into each bottle, so everything else has to stay the same. If you continue to use this site we will assume that you are happy with it. Mentos Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. Mentos and Coke Experiment How to Do It! This hands-on experiment is easy to do and simply involves dropping Mentos into a bottle of diet soda and running away. The Mythbusters also correctly identified the roughness of the samples as one of the main causes of the reaction. Never use a stove or a microwave to heat a bottle of soda. We compared dropping 16g of Mint Mentos into a 1l bottle of seltzer water (carbonated water), a 1l bottle of tonic water (carbonated water, high fructose corn syrup, citric acid, natural and artificial flavors, and quinine), and a 1l bottle of diet tonic water (carbonated water, citric acid, natural and artificial flavors, aspartame, potassium benzoate, and quinine). The seltzer and tonic water trials had the same expiration date and were manufactured by the same company. [17] This record was afterward beaten in November 2014 by another event organized by Perfetti Van Melle and Chupa Chups in Len, Guanajuato, Mexico, where 4,334 Mentos and soda fountains were set off simultaneously. Hypothesis: If the amount of soda in the bottle decreases, then the height of the plume and velocity of the liquid will also decrease because there will less liquid with which the Mentos can react. We used a FEI Quanta 200 electron scanning microscope. If you want a more specific measurement, use chalk to mark off 1-foot increments before you drop the Mentos into the bottle of soda. [10] As another example, dropping grains of salt or sand into the solution provides Type IV nucleation sites, lowers the activation energy compared to that of homogeneous nucleation, and increases the rate of carbon dioxide degassing. This must been coined as the Pepsi Paradox. (2019, December 18). Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. The average times were 0.7s for the Mentos, 1.0s for the rock salt and the Lifesavers, and 1.5s for the sand. We put 4 mentos pieces into the bottle of diet coke. Rough candy Measurements showed that the surface tension in water containing the sweetener aspartame is lower than in sugary water, explaining why Diet Coke creates more dramatic fountains than sugary Coke. View the Mentos Geyser Experiment here! Some of the samples, such as the table salt, molecular sieve beads, and the sand grains, were too rough to image in our AFM, which has a 24mz range. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. We have shown here via contact angle measurements that these ingredients reduce the work required for bubble formation, allowing carbon dioxide to rapidly escape from the soda. Grobe, F., & Voltz, S. The Science of Coke and Mentos. 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. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. From our results in Tables I and II we see that the rock salt performance far exceeds the table salt performance, even though the surface area to volume ratio (and hence the number of bubble growth sites per gram) is larger for the table salt. The uncertainty of the fall times was roughly 10%. Try placing the soda bottle next to the wall of a brick building, after getting permission from the buildings owner, of course. [20][12][14][17] It has been claimed that gelatin and gum arabic in the Mentos candy enhance the fountain,[12][14][26] but experiments have shown that these candy additives do not affect the fountain. It should not introduce any new information, but rather summarize the key points made in the discussion section. When you open the container, the bubbles quickly rise to the top, pushing the liquid out of the way, so liquid sprays everywhere. Today Room 1 and 5 did a science experiment together. Superabsorbent giant growing polymer beads that absorb 150 times their weight in water! Then, observe, record and report the results. Mentos and Coke Experiment How to Do It! Originally it was thought that the colossal fountain of soda spraying out of the bottle was caused by the caffeine in Coke. Of course, this could go on forever, but youll start to see a trend in your data that shows the maximum height of the geyser. There really arent that many supplies you need to make a mentos and coke volcano. The Diet 2.) The scientific method is an important way scientists make observations and come to conclusions. The quantitative roughness information detailed in Table V was taken from this image. Great integration of science and literature. Mentos and Diet Coke Experiment. Make sure your scale is in place, whether youre measuring by counting bricks or using an alternative method. The question in the hypothesis was answered too, with the answer being no. As mentioned earlier in the article, using either diet coke or regular coke alongside mentos can produce a spewing geyser of carbonation bubbles. The majority of us have probably experimented with dropping multiple sugary, round mentos into a bottle filled to the brim with coke. This high school science fair project investigates if small changes in your diet alter the pH of your saliva. The Amazing Scientist Chemistry Kit is designed to get your young scientist interested in chemistry. What is inside Mentos and cola that reacts with each other causing the eruption? Hypothesis: The larger the number of mentos, and the warmer the temperature of the soda, the higher the reaction will be. To compare two systems, we calculate a ratio of the works required for bubble formation: We used this technique to compare the work required for formation of a bubble in deionized water to other liquids, as summarized in Table IV. We even played with ways to use the Geyser Tube to trigger multiple soda geysers in a method similar to a Rube Goldberg machine. We found that the max amount of mentos with the largest Kilauea, for example. View the Mentos Geyser Experiment here! This low temperature allows the maximum amount of carbon dioxide to dissolve into the soda, keeping the carbonation levels as high as possible. As luck would have it, the solution to the problem was within arms reach of the Wintergreen LifeSavers in the candy aisle: Mentos chewy mint candies! To directly compare the aspartame with the potassium benzoate we dropped 16g of Mint Mentos into a 1l bottle of seltzer water with 7.5g of added potassium benzoate and the same amount to a 1l bottle of seltzer water with 7.5g of added aspartame. The Mythbusters identified the active ingredients in the Diet Coke that contribute to the Mint MentosDiet Coke reaction: caffeine, aspartame, and potassium benzoate, a preservative.1 As shown by the agreement within the 10% experimental error of the mass lost and distance traveled by the sodas spray for Mint Mentos in Diet Coke compared to Mint Mentos in Caffeine Free Diet Coke (see Tables I and II), the presence or absence of caffeine in the beverages contributes little to the reaction. The enthusiasm for dropping mints into soda bottles continues to grow today. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. WebThis product walks you through the scientific method using two different experiments: -- How different types of soda react when Mentos is added to them- How Coke reacts to Mentos vs. how it reacts to baking sodaStudents will make an observation, ask a question, create a hypothesis, conduct an experiment, record results, and write a conclusion. WebFun Science Experiments // Mentos and Coke / Soda ExperimentIncludes BOTH US size and Australian A4 sized files/spelling!This fun experiment explores the physical reaction [20] It has also been demonstrated that addition of certain concentrations of alcohol (which lowers surface tension) to carbonated beverages decreases fountain heights. What Will I Need For The Mentos And Coke Volcano? [13] The Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. What is a good hypothesis for Mentos and Diet Coke? St. Helens and Mt. This was demonstrated in an experiment that tested 15 types of carbonated beverages with Mentos. The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. He will be performing the crushed vs whole candy in a diet coke. We constructed a bottle stand (roughly 10 off vertical) to prevent the bottles from tipping over and the liquid from falling back into the bottle. Some helpful comments were made by the anonymous referees. However, scientists are finding that theres more to this spectacular demonstration than meets the eye. Repeat the process, varying the opening that the soda erupts from. During the commercial break, I told Kim what was going to happen and reminded her to pull her hand out of the way of the erupting geyser and to run backward. They both ended up having 1 oz out of 8 oz ounces leave the beaker and into the air around too. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar.
