conclusion for coke and mentos experiment

Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. The blend of Coke Zero and Mentos just works out the strongest. This is why bottling plants pump carbon dioxide into the cans or bottles when the fluid is just above freezing, usually around 35 degrees Fahrenheit. The bubbles then act as growth sites, where the carbon dioxide still dissolved in the solution moves into the rising bubbles, causing even more liberation of carbon dioxide from the bottle. What is the conclusion of Mentos and Coke experiment? 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. Does warm Diet Coke create a greater geyser explosion than cold Diet Coke does? 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! Everyone found their own method for quickly dropping the Mentos into the soda. The warmer the liquid, thelessgas can be dissolved in that liquid. 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. The hands-on experiment involves dropping several Mentos Chewy Mints into a bottle of Diet Coke, which can cause a stream of the diet cola to shoot many feet Well, its probably not pretty. To make any of these tests meaningful, youll need to find a way to measure the height of the eruption. Try placing the soda bottle next to the wall of a brick building, after getting permission from the buildings owner, of course. 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 speed with which the sample falls through the liquid is also a major factor. What is a good hypothesis for Mentos and Diet Coke? Once the geyser stops, measure how much liquid is left inside. [9][10], In the 1910s, Wint-O-Green Life Savers were used to create soda geysers. 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. 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). 2.) https://easyscienceforkids.com/diet-coke-and-mentos-video-for-kids/. Put the index card on top of the tube loader and turn the tube upside down. The scale bars in each image represent the lengths (a) 200m, (b) 100m, (c) 20m, and (d) 20m. Remember, when youre doing an experiment, you can only change one variable. Better yet, if we could trigger the drop of the Mentos from a distance, we wouldnt get as wet. A large fountain of coke then comes rushing out, oftentimes multiple metres in the air, causing a sticky mess all over the place. These ingredients accelerate the foaming action of the soda very quickly, causing the infamous explosion. Part of his assignment Is to ask a professional about his experiment. Lets start with seven Mentos for our first attempt. The Diet Coke and Mentos experiment results from the nucleation of carbon dioxide from liquid to gas. Sticking a finger into a glass of soda will result in the formation of tiny bubbles full of carbon dioxide that stick to the skin. Regular soda becomes a sticky mess because it contains sugar, while diet soda uses artificial sweeteners instead of sugar, so its not as sticky. 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.). What causes the explosion when Mentos are dropped into the Diet Coke? While the reaction remains fairly the same regardless of what carbonated beverage you use for this experiment, diet sodas are usually more carbonated and fizzy compared to regular sodas. The Wint-o-Green Lifesavers are rougher than the Mentos by a factor of 5, but the mass lost during these reactions is comparable. The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. 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. Does the amount of Mentos affect the height of the explosion? Diet Coke On a 100m2 scale, the Wint-o-Green Lifesavers have a rms roughness that is more than a factor of 10 larger than the rms roughness of the rock salt. Introduce the concepts of chemical bonding, cross-linking of molecules. Learn more about how plants work with this cool celery experiment! Later on in the experiment, youll be invited to compare the geyser power of diet versus regular soda, but for now well start with a 2-liter bottle of diet soda. WebThe Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. What happens when you mix Diet Coke and Mentos? And its a great way to learn about chemical reactions. 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. Henrys law applies to gases dissolved in liquids, such as the carbon dioxide gas dissolved in Diet Coke and other sodas. 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. 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. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. Record your observations in a logbook. The diet coke erupted like a volcano. 4, and some of the AFM images are shown in Figs. 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. These claims are also supported by data from the liquid gum arabic trials. 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. Hall, Magdalena Jaramillo, Cully Little, and Zach Russell, and my graduate research assistant, Jon Jones. 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 WebKids TV Yenu and Sanu is home to gaining knowledge & entertain toddlers. 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? Observe the eruptionheight, trajectory, duration, etc. 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. You might need to put down something flat, like a small piece of wood, to hold it up. 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. Since diet sodas lack the sugar that regular ones do, it has lower viscosity and surface tension. The lack of change in the pH supports the conclusion that the Mint MentosDiet Coke reaction is not an acid-base reaction. students used this simple device to monitor the kinetics of foam production in the Diet Coke and Mentos experiment and to draw conclusions about the system. (As discussed, part of the reason that the Wint-o-Green reaction took more time is due to the increased fall times.) What happens when you drop Mentos in a bottle of coke? 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. With 5 or 6 mentos the explosion went only 330 and 310 cm high. You want the bottle to be stable before conducting the 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. This bubbling process is called nucleation. This study began as a project for physics majors enrolled in a sophomore level physics lab course. Science project. It should not introduce any new information, but rather summarize the key points made in the discussion section. ), A tube the width of the Mentos. The child who died from combining Mentos and Coca-Cola story is an updating of an older legend that began in 1979. 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. Its time to return to your launching site. 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. 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. There are two major reasons for this discrepancy. The Diet Steve Spanglers Geyser Tube toy (optional . Oddly enough, this container was actually a pre-form or 2-liter soda bottle before it was blown up into a big bottle. In the Mentos and Diet Coke experiment, Arnold was trying to prove that the Diet Coke would explode if he put What is the hypothesis of Mentos and soda? Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. Note that the contact angle for the aspartame and potassium benzoate solutions is less than the contact angle for pure water, indicating a decrease in the surface tension. The Mythbusters correctly identified potassium benzoate and aspartame as key ingredients in the Diet CokeMentos reaction. SEM images of table salt, acquired with a beam energy of 5.0kV and a spot size of 5nm. Youve probably heard that you shouldnt eat Mentos while you drink Coke, but why is that? The average distance traveled by the sodas spray during the explosion is given in Table II. Fast-moving mentos create larger explosions while slow, powdered mentos create tiny ones (Muir, 2008). We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. The higher magnification image of the Fruit Mentos is zoomed in on one of the rougher patches. Why do Mentos turn ordinary bottles of diet soda into geysers of fun? The reaction has been performed numerous times on television and the Internet, but has not been systematically studied. Using any more than seven Mentos mints is just a waste, according to these soda-soaked science enthusiasts. As they say, the rest is history. But it has nothing to do with the mint Mentos actual flavor. The question was asked on a special College Week episode of Who Wants to Be a Millionaire. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. ", "MythBusters: Diet Coke and Mentos MiniMyth", "Toying with the Diet Coke and Mentos experiment", "How Many Bubbles Are in the Foam Produced during the Candy-Cola Soda Geyser? If spectators were watching your exploits, someone is bound to yell out, Do it again! Thats exactly what youre going to do. 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. Before you get started, youll need to find a location suitable for the experiment. Now remove the index card and let candies fall in and step away from the Mentos and coke volcano. The dependent variable was the height of the rise of Coca-Cola. Just mix the two liquids and get more than 300 feet of Instant Worms. Does the flavor of Mentos affect the explosion? Why does the coke react to Mentos? So, Im going to go with Mentos. This science demonstration was popular among chemistry teachers back in the 1980s. The author would like to thank the Dewel Microscopy Facility for their donation of the time on the SEM. The parameter K changes with temperature, generally increasing as the temperature increases. Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water. Hypothesis: If a certain amount of Mentos are dropped into a container of soda, then the container with the most Mentos dropped into it will produce the most CO2 at the fastest rate. Conjure a magical genie inside a root beer bottle, awaken a thirsty ghost, use your amazing brainpower to read minds, and more. And you may not have a friend for a day or two until they forgive you. We used a FEI Quanta 200 electron scanning microscope. Subtract the remaining amount of liquid from the original volume of the bottle to calculate the volume of the geyser. Set up three tests: warm soda, room temperature soda and cold soda. 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. The places where the bubbles form are the nucleation sites. The scale bars represent the following lengths: (a) 2.0mm; (b) 100m, (c) 50m, and (d) 20m. In this experiment, you will evaluate whether or not a diet that is supplemented with "brain-enhancing" foods can help improve memory. This hands-on experiment is easy to do and simply involves dropping Mentos into a bottle of diet soda and running away. Note be sure to only try this experiment with a responsible adult! Now, its time to run away. Load seven Mentos into your paper roll or yourGeyser Tubeand drop them into the soda and immediately record the data. Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle. Diet Coke 280 8.6 Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. Learn all about the secrets that make seeds grow and the conservation power of Water Jelly Crystals. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. To add insult to injury, she did it two more times. Amazing Facts About Diet Coke And Mentos Experiment. Quantitative Observation All of the Coca-Cola products had the same expiration date, so the level of carbonation in each 2l bottle should be similar. 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. Mentos and Coke Experiment How to Do It! It truly is the perfect chemistry kit for kids who want to explore. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. 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. [13] The Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. Their explanation is this process called nucleation. Assuming that youre using the paper tube method, youll want to load the seven Mentos into the tube, cover the bottom of the tube with your finger and position the tube directly over the mouth of the bottle. It doesnt matter what your variable is, it just has to be one concrete thing that you can change. The images were acquired with a beam energy of 12.5kV and a spot size of 5.0nm. So aspartame causes the most mass lost. This will work on any drink that is carbonated. 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. What is the dependent variable in Coke and Mentos experiment? The carbon dioxide attaches throughout the bead, increasing the amount of time over which the reaction occurs. The question in the hypothesis was answered too, with the answer being no. But when the gum arabic was injected into the middle of the bottle, no mass was lost. 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. Write down what you think will happen when placing the Mentos in the soda. Use your data from the previous test to determine the standard number of Mentos candies to use for this test. Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. half a roll) in the test tube. How does the temperature of the soda affect the height of the soda stream when Mentos are added to soda? First, we learned that the massive buildup of pressure occurs when carbonation causes bubbles to accumulate on the surface of the Mentos. Learn all about the science of seeds and have fun getting your hands in the dirt. The liquid samples, including the gum arabic, the baking sodawater mixture, and the Dawnwater mixture, were administered by injection using a 10ml syringe with an 18-gauge needle. The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. Figure 1(c) is a magnified view of the edges of a salt grain, and Fig. The Mythbusters team did a wonderful job of identifying the basic ingredients in this reaction. 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. 1(d) is a magnified view of the top of a salt grain. Contact angle measurements were made by placing small drops of the liquid solutions on a flat polycarbonate surface, photographing the drops, and measuring the contact angles from the photographs (see Fig. 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. The activation energy for bubble nucleation (formation of bubbles) depends on where the bubble forms. The basic science of the Coke and Mentos reaction is fairly straightforward. [1], Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. Follow our step-by-step instructions in our Mentos Geyser Experiment to find out. These calculations are approximate, but are consistent with our results reported in Tables I and II. The Amazing Scientist Chemistry Kit is designed to get your young scientist interested in chemistry. The scientific method is an important way scientists make observations and come to conclusions. Soda is made of sugar or artificial sweetener, flavoring, water and preservatives. KUSA-TV News posted that original video on their website along with my blog post titled, News Anchor Gets Soaked! Within a few weeks, links to the video and my blog entry numbered in the thousands. 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. Unfortunately, Kim got so caught up in the fun that she forgot to do both and got soaked in Diet Coke on live television! Kilauea, for example. Hence it is the combination of a rough surface and the surfactant in the outer coating of the candy that causes the impressive reactions.
