The Amazing Scientist Chemistry Kit is designed to get your young scientist interested in chemistry. 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. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. WebCONCLUSIONS: ( Do you accept or reject your hypothesis, and why or why not) You and your partner will share your experiment with the class. The uncertainty is approximately 10%. The kit comes with the essential materials youll need to conduct 6 experiments, take-it-further activities and challenges for 1 4 children per kit. Drinks sweetened with aspartame, such as diet Coke or the diet tonic water, are more explosive than drinks sweetened with sugar (corn syrup), which is likely due to a reduction in the work required for bubble formation when aspartame is added. Lee Marek and Mareks Kid Scientists performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. Why Do Diet And Coke Zero Have A Better Reaction With Mentos? This increase means that the molar concentration of the gas in the solution must drop for the same value of the partial pressure, which implies that gases become less soluble in liquids as the temperature increases. The Mythbusters also correctly identified the roughness of the samples as one of the main causes of the reaction. The average times were 0.7s for the Mentos, 1.0s for the rock salt and the Lifesavers, and 1.5s for the sand. Does Colorado have a defensive driving course? [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. Many soda geyser-ologists believe that seven Mentos candies produce the highest shooting geyser. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. However, you wont get the same effect from eating Mentos after drinking Coke. The only variable youll change in this test is the brand of soda; everything else will remain the same. We found that the max amount of mentos with the largest To maintain consistency we also constructed a tube to fit over the mouth of the bottle and a delivery mechanism for the solid materials. They both ended up having 1 oz out of 8 oz ounces leave the beaker and into the air around too. The pH of the Diet Coke after the baking soda reaction was 6.1, indicating that much of the acid present in the Diet Coke was neutralized by the reaction. Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. It is clear from Table V that the roughness of the sample is a major contributor to the explosiveness of the reaction. By the end of the 1990s, however, the manufacturer of Wintergreen LifeSavers increased the size of the mints (no one was ever certain why). Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. Kilauea, for example. The Mythbusters team did a wonderful job of identifying the basic ingredients in this reaction. 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! Write down what happened when you dropped the Mentos in the coke. Use your data from the previous test to determine the standard number of Mentos candies to use for this test. Oddly enough, this container was actually a pre-form or 2-liter soda bottle before it was blown up into a big bottle. 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. However, scientists are finding that theres more to this spectacular demonstration than meets the eye. https://www.scientificamerican.com/article/bring-science-home-coke-mentos/. The average amount of mass lost for the various combinations of soda and samples is given in Table I. Make sure the candies are in line with the mouth of the bottle. The seltzer and tonic water trials had the same expiration date and were manufactured by the same company. Conclusion Hypothesis: In the experiment I expect the Pepsi and Mentos reaction to be at least 30cm in height, however, I expect it to be short lived due to the fact that the sodium level of the beverage is only 10 mg. A soda geyser is a reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. 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. Dropping something into the Diet Coke speeds up this process by both breaking the surface tension of the liquid and also allowing bubbles to form on the surface area of the Mentos. In fact, its not really a reaction at all or at least its a physical reaction rather than a chemical one. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. In an experiment, you have two groups: an experimental group, and a control group. WebPut 5 room temp Mint Mentos in a geyser tube. View the Mentos Geyser Experiment here! The thing that makes soda bubbly is invisible carbon dioxide, which is pumped into bottles at the factory using lots and lots of pressure. That year, the grist being run through the rumor mill included the sad tale of a misadventuring tot who had gulped soda and ingested Pop Rocks, a carbonated candy known for producing a fizzling sensation in the mouth. Does the amount of Mentos affect the height of the explosion? Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. As they say, the rest is history. For the Mint Mentos and baking soda trials, the pH of the Diet Coke before and after the reaction was measured by a pH meter with a two point calibration. Many consider Diet Coke to be the optimal option, and it's been studied and confirmed as having the strongest effect. 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.). This experiment can be visually displayed with photos or videos of the event and a graph of the tables results. 13, contact angle images are shown in Fig. What is the dependent variable in Coke and Mentos experiment? 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. Bookmark this to easily find it later. There is not always a direct correlation between the mass lost and the distance traveled for the reactions. 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. A two-liter bottle of diet soda (diet soda makes for a much better reaction, but you can use regular soda if you like. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in the water. Each bottle will receive a different number of Mentos. We use cookies to ensure that we give you the best experience on our website. We knew the Mentos Geyser Experiment was a popular experiment when a producer from ABCs Who Wants to Be a Millionaire called for help when writing a question. Originally it was thought that the colossal fountain of soda spraying out of the bottle was caused by the caffeine in Coke. Hence it is the combination of a rough surface and the surfactant in the outer coating of the candy that causes the impressive reactions. WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. So, Im going to go with Mentos. The parameter K changes with temperature, generally increasing as the temperature increases. [12] The blend of Coke Zero and Mentos just works out the strongest. Sample morphology was determined by imaging the samples in an environmental scanning electron microscope (SEM).4 The uncoated samples were imaged in low vacuum mode. 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. 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. Warning - you are about to disable cookies. Mentos and Diet Coke Experiment. The author would like to thank the Dewel Microscopy Facility for their donation of the time on the SEM. What is the hypothesis of Mentos and soda? State briefly what you tried, what were your results, and what you might do differently next time. A one gallon bucket containing test tubes of over 10 Spangler Labs originals, Features favorites like Insta-Snow, Energy Beads, Jelly Marbles, & Magic Sand. Mentos and Coke Experiment How to Do It! So aspartame causes the most mass lost. 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. Spurting Science: Erupting Diet Coke with Mentos. The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. According to our experiment, however, the SEM images show that the shiny, brightly colored coating on the Fruit Mentos is not uniform and rough patches are exposed (see Fig. For the MentosDiet Coke reaction, the carbonic acid and carbon dioxide are not products of a chemical reaction but are already present in the Diet Coke, whose equilibrium is disturbed by the addition of the Mentos. 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. This, in turn, allows the soda to form smaller bubbles that can retain its structure for longer due to the reduced surface area of the bubble. Adding salt to soda also causes it to foam because thousands of little bubbles form on the surface of each grain of salt. ), Vampire Slime Light Sensitive Color-Changing, STEM Science Kit: Amazing Scientist Chemistry Kit, Big Bucket of Science Test Tube Experiments, A roll or box of Mentos chewy mints (stick with the standard mint flavor for now), 2-liter bottle of diet soda (either diet or regular soda will work for this experiment, but diet soda is not sticky when youre cleaning it up, and it will usually create a bigger blast). Once the geyser stops, measure how much liquid is left inside. 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. 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. [12][14] Spangler signed a licensing agreement with Perfetti Van Melle, the maker of Mentos, after inventing an apparatus aimed to make it easier to drop the Mentos into the bottle and produce a large soda geyser. 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 The question in the hypothesis was answered too, with the The speed with which the sample falls through the liquid is also a major factor. These tiny pits act as nucleation sites, which are perfect for carbon dioxide bubbles. This phenomenon is an illustration of Henrys law given in Eq. Spanish-English dictionary, translator, and learning, Marketplace for millions of educator-created resources. At the time, my solution was to load the Mentos candies into something called a Baby Soda Bottle a test tube-like container that held an entire roll of Mentos perfectly. The images were acquired with a beam energy of 12.5kV and a spot size of 5.0nm. How many protons and electrons are present in Ba2+? Turn from eerie green to blood red when you hold it up to the light. Primarily, the sugar, aspartame and potassium benzoate included in the candy shell reduce the work it takes to form bubbles in the soda, causing a rapid creation of carbon dioxide bubbles. Why Do Flight Attendants Hate Serving This Drink to Passengers in Flight? As the liquid is heated, the gas within that liquid is also heated, causing the gas molecules to move faster and faster. What is the conclusion of Coke and Mentos? The lower magnification images show large surface areas and small volumes, especially when compared to samples such as a Mentos, which is 12cm in diameter. students used this simple device to monitor the kinetics of The temperature was 52 F. In this experiment, mentos caused a eruption in a 2-liter bottle of Diet Mountain Dew erupted, thus we concluded that diet Mountain Dew Set up 16oz coke bottle and attach geyser tube and launch. WebDiet coke and mentos explained: We explain the science behind the Diet Coke and Mentos experiment: The mint sweets provide a surface for the gas in the cola to cling on to. Science teachers started experimenting (as they like to do) with other candies and mints that would have the same effect when dropped into a bottle of soda. Big news media outlets like The Wall Street Journal, Rolling Stone and GQ Magazine wrote about the experiment which helped it become known worldwide like we see today (Grobe & Voltz, n.d.). The intensity of the reaction was determined by measuring the mass of the bottle using a double pan balance before and after the reaction to determine the mass lost in the reaction and by measuring the horizontal distance traveled by the sodas spray. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. 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. References: The references section lists all the sources that were cited in the SIP, including articles, books, and Soda is made of sugar or artificial sweetener, flavoring, water and preservatives. QUESTIONS: 1. What is the independent variable in Coke and Mentos experiment? If youre not using the Geyser Tube, make sure to come up with your own method for dropping the Mentos into the soda exactly the same way each and every time. Mentos candies contain millions of cavities, roughly 1-3 m in size,[25][10] that remain unwetted when added to a soda. In this project, you'll create Oersted's experiment, which relates to how electric currents create magnetic fields. It proved challenging to get away from that bottle before it exploded. The scale bar for (a) is 100m and for (b) is 20m. 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. 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. Thats my final answer.. Your kid may be surprised to learn that the density of coke and diet coke aren't the same! Use this worksheet to help you record your observations after doing this experiment. Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. The potassium benzoate and the aspartame are active ingredients in the Mint MentosDiet Coke reaction, but the aspartame likely contributes more to the reaction. Today, all of that will be answered in our article down below! The activation energy for the release of carbon dioxide from Diet Coke by the addition of Mentos is 25 kJ mol1. Their explanation is this process called nucleation. You might need to put down something flat, like a small piece of wood, to hold it up. If the partial pressure of the gas above the liquid is higher, then more gas can be dissolved in the liquid. Youll need a thermometer to record the temperature of the soda just before you launch it so that your data are accurate. Place the second bottle in a place where it will reach room temperature overnight. 1 So the relatively small amount of caffeine in a 2 l bottle of Coke doesnt significantly affect the reaction. Toll Free: 800-223-9080 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. 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. [25] These results suggest that additives serve to enhance geyser heights not by decreasing surface tension, but rather by decreasing bubble coalescence. Youll need lots of soda and Mentos, as well as a few friends to help record all of the data. http://www.eepybird.com/featured-video/coke-and-mentos-featured-video/science-of-coke-mentos/, 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. At the end of the 1990s, the manufacturer of Wintergreen Lifesavers increased the size of the mints, and they no longer fit in the mouth of soda bottles. The pressurized conditions of the bottle and the surface tension of the water keep the gas in solution, even though it wants to escape (the gas that escapes makes the fizzy sound you hear when you open the bottle) (Science Buddies, 2012). The Coke and Mentos Experiment is an easy science experiment to do with kids of all ages. Even toddlers and preschoolers will shriek with delight as they watch this chemical reaction take place. Use the hot glue gun to glue 7 - 8 mentos together. This is optional, it just helps to add all of the mentos into the bottle at the same time. [Full Guide] - Cool Some people fashioned a tube out of paper; others used a piece of plastic tubing to load the Mentos. Notice how bubbles immediately form on the surface of the object. Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. If we assume that LV is similar for Diet Coke and Caffeine Free Diet Coke, then the work required for bubble formation for Diet Coke is 90% of the work required for bubble formation for Caffeine Free Diet Coke. [31] As for the Mentos, many things work to nucleate carbonated beverages such as other candy, metal and ceramic spheres,[32] and even sand.[33][34]. The Mentos mints then dropped into the soda. In addition to the six outlined experiments, weve included suggestions for further fun, giving your future chemist more opportunities to learn and grow. . WebThis is a fun and exciting experiment designed for 3rd-6th graders. The popular Diet Coke and Mentos reaction occurs when new Mentos are dropped into a fresh bottle of Diet Coke and results in a jet of Diet Coke spray shooting out of the mouth of the bottle. Repeat the process, varying the opening that the soda erupts from. Average mass lost during the reaction. A search on Google for Diet Coke and Mentos will return millions of hits, and YouTube has many home videos of this reaction. With 5 or 6 mentos the explosion went only 330 and 310 cm high. It has also been shown that a wide variety of beverage additives such as sugars, citric acid, and natural flavors can also enhance fountain heights. WebWith the Coke and mint mentos experiment, coke and fruit mentos were very similar as the coke and mint mentos took 31 seconds to complete the reaction while coke and fruit mentos took 22 seconds to complete in total. 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 answer is yes. This will happen because the dissolved CO2 will provide the most nucleation sites to come out of the solution. The dependent variable was the height of the rise of Coca-Cola. This size image was chosen for comparison between samples because the samples imaged were quite rough and had significant curvature, and images larger than 100squarem often resulted in a z range larger than 24m. When the candy hits the bottom of the bottle, the gas is released and pushes the soda from the bottle up in the air in an amazing eruption! Place the soda bottle outside in and area that can get dirty. The lower magnification image of the Fruit Mentos has smooth patches in contrast to the lower magnification image of the Mint Mentos, but the candy coating is not uniform. I also posted the video on a new online video-sharing site called YouTube (YouTube was only seven months old at that time). WebConclusion Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. Dog Diets: Will a Dog Prefer Homemade Dog Food? But it has nothing to do with the mint Mentos actual flavor. 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. Introduce the concepts of chemical bonding, cross-linking of molecules. The experiment became a subject of the television show MythBusters in 2006. An impressive acid-base reaction can be generated by adding baking soda to Diet Coke. Quantitative surface roughness measurements were made with a Digital Instruments contact mode atomic force microscope (AFM) with Nanoscope III control electronics and a J type scanner with a 24m z range. Load seven Mentos into your paper roll or yourGeyser Tubeand drop them into the soda and immediately record the data. The majority of us have probably experimented with dropping multiple sugary, round mentos into a bottle filled to the brim with coke. ", "Tribonucleation: A New Mechanism for Generating the Soda Geyser", "The problem with the Coke & Mentos experiment that few people know about", https://en.wikipedia.org/w/index.php?title=Soda_geyser&oldid=1149860252, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 14 April 2023, at 21:58. 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. Compare the contact angle results in Table V for pure water (=85), sugar water (=80), and aspartame dissolved in water (=77). Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. This demonstration illustrates many important ideas in physics, including key principles in thermodynamics, surface science, and the physics of eruptions. 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. Pre-existing bubbles provide a way for the reaction to occur without requiring bubbles to form within the liquid itself (homogeneous nucleation). Heres the question we came up with: In an experiment popularized online, what candy creates an explosive geyser when dropped into a 2-liter Diet Coke bottle? 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. Due to the small amount of caffeine in a 2l bottle of Diet Coke, we do not agree that the caffeine in Diet Coke contributes significantly to the reaction. 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. The basic science of the Coke and Mentos reaction is fairly straightforward. The scale bars in each image represent the lengths (a) 200m, (b) 100m, (c) 20m, and (d) 20m. WebMentos and Soda Experiment | Eepy Bird The Extreme Diet Coke & Mentos Experiments About The Extreme Diet Coke & Mentos Experiments This is the video that started it all: a backyard experiment became a cultural phenomenon. We examined the reaction between Diet Coke and samples of Mint Mentos, Fruit Mentos, a mixture of Dawn Dishwashing detergent and water, playground sand, table salt, rock salt, Wint-o-Green Lifesavers, a mixture of baking soda and water, liquid gum arabic, and molecular sieve beads (typically found in sorption pumps). All of the Coca-Cola products had the same expiration date, so the level of carbonation in each 2l bottle should be similar. What happens when you mix Diet Coke and Mentos? The diet coke erupted like a volcano. WebSince which invention of cola, the gegner between Pepsi and Coca-Cola (i.e., Coke) has had in existence. 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. The measured contact angles and minimum works for bubble formation are given in Table IV. We launched the Mentos Geyser Tube toy at the New York Toy Fair in February 2007.

From after-school activities and science classroom activities to STEM club experiments, our website is one of the most trusted resources for fun, age-appropriate experiments for kids of all ages. Part of his assignment Is to ask a professional about his experiment. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. All fizz shooting out in one strong plume. Afterwards, Grobe and Voltz appeared on many renowned television programs, such as Ellen, HBOs The Comedy Festival to talk about their viral video and they were even invited to other countries like France, Turkey and Belgium. Although mentos look smooth, they are in fact covered with layers upon layers of bumps and rough edges, making them filled with nucleation sites. The amount 54020g of mass was lost from the diet tonic water, 43020g of mass was lost from the tonic water, and 945g of mass from the seltzer water. eleanorrigby-movie.com 2023 [3] Steve Spangler's televised demonstration of the eruption in 2005 became popular on YouTube,[4][5][6] launching a chain of several other Diet Coke and Mentos experiment viral videos. 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. 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. Within seconds of dropping the candies into the soda, a huge geyser would erupt from the bottle. Each time, she was covered in more soda until her once-pink dress was now more Coke-colored than pink! Contact mode AFM image of Mint Mentos. Compare your notes on the experimentto the control group. Le Chateliers principle states that, If, to a system at equilibrium, a stress be applied, the system will react so as to relieve the stress.6 In our experiment the stress we are applying increases the temperature of the Diet Coke. We report on an experimental study of the Diet Coke and Mentos reaction, and consider many aspects of the reaction, including the ingredients in the candy and soda, the roughness of the candy, the temperature of the soda, and the duration of the reaction. Learn all about the secrets that make seeds grow and the conservation power of Water Jelly Crystals. Better yet, if we could trigger the drop of the Mentos from a distance, we wouldnt get as wet. Start by opening the cold bottle and dipping the thermometer into the soda. Dont forget to look back at the amazing eruption of soda. The Diet CokeWint-o-Green reaction loses more mass and the spray travels farther than the Diet Cokerock salt reaction. This high school science fair project investigates if small changes in your diet alter the pH of your saliva. roll of Mentos candies (any flavor) 2-liter bottle of soda (diet soda is less sticky; diet cola seems to produce the best fountain) index card or sheet of paper. A variety of containers with varying sized opening, A narrow test tube wide enough to fit the candy [Klutz and others make a delivery contraption that is easier.]. Its important to use the same number of Mentos for each test and to drop them into the soda bottles the exact same way. Depending upon the number of Mentos dropped into the bottle, the spray height can vary between a few inches and tens of feet. It is very simple to do and requires minimal tools and equipment to execute correctly. ), A tube the width of the Mentos.
