Parts of science investigatory project. Science Investigatory Compare these times to the mass lost and distance traveled results in Tables I and II. The contestant ended up doing really well, going all the way to the $250,000 question; however, he walked away with $125,000. Dont miss our other super-fun and hands-on experiments in our huge online experiment library! In this project, you'll create Oersted's experiment, which relates to how electric currents create magnetic fields. 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. Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. Many consider Diet Coke to be the optimal option, and it's been studied and confirmed as having the strongest effect. These calculations are approximate, but are consistent with our results reported in Tables I and II. WebPut 5 room temp Mint Mentos in a geyser tube. 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. The activation energy for the release of carbon dioxide from Diet Coke by the addition of Mentos is 25 kJ mol1. Thank you so much. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. Just mix the two liquids and get more than 300 feet of Instant Worms. What evidence did the team find that the reaction between the Mentos and soda was a physical change? From Table III we see that higher temperatures lead to larger eruptions. You want the candies going in the bottle and not falling over the side. The Diet Coke and Mentos reaction was the subject of a 2006 Mythbusters episode1 and first shown in 1999 on the David Letterman Show, and has become a popular in-class physics and chemistry demonstration from elementary school to college level classes. 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. Have you ever taken a can of soda, shook it up, and given it to your friend? This chemistry science kit includes activities for solo and group experiments, making it a fantastic addition to your classroom or for fun at home. Longer distances traveled by the bubbles resulting in a more explosive reaction also partially explains the differences in explosive power for whole Mentos in contrast to crushed Mentos; the smaller particulates of the crushed Mentos fall through the liquid more slowly. How can I download Tekken 7 on Windows 7? Carbon dioxide creates the bubbles in soda. Our AFM measurements show that the rms roughness of the Fruit and Mint Mentos surfaces are comparable (see Table V). The average amount of mass lost for the various combinations of soda and samples is given in Table I. The answer is yes. The images were acquired with a beam energy of 12.5kV and a spot size of 5.0nm. Bookmark this to easily find it later. Mentos and Diet Coke experiment works with any soda And you may not have a friend for a day or two until they forgive you. In Eq. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. WebFInally, the average height of the hot bottles' geysers was 19.5 inches and was the greatest. This experiment investigates if small changes in your diet can alter your basal body temperature. Given the ingredients listed on Diet Coke, there is more aspartame than potassium benzoate in Diet Coke per unit volume. 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. What is the independent variable in the Mentos and Diet Coke experiment? What are the independent and dependent variables in Coke and Mentos? Contact mode AFM image of Mint Mentos. 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. Record your observations in a logbook. 2.) When the gum arabic was injected at the bottom of the bottle, 100g of mass was lost. While science teachers have been dropping candies and mints into 2-liter bottles of soda for years in an effort to release all of the dissolved carbon dioxide, the Mentos and Diet Coke reaction became world-famous in 2005. Mentos You can also use a Baby Soda Bottle to hold the Mentos or a Geyser Tube, which was invented to solve this very problem. Well, its probably not pretty. 3 I recently led a large group of undergraduate physics students in a cooperative research project to Does one brand produce higher geysers? Most importantly, the author would like to thank the students of PHY2210 for their hard work and great ideas, including Will Beuttell, Jason Burch, Blake Clark, Robert Duke, Jama Greene, A.J. Use your data from the previous test to determine the standard number of Mentos candies to use for this test. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. (4) next and Le Chateliers principle.6. Place the soda bottle outside in and area that can get dirty. Overall I expect the Pepsi and Mentos to create a fountain like reaction. The winning Geyser Tube design was a clear plastic tube with a special fitting that twisted onto any soda bottle. What is the conclusion of Mentos and Coke experiment? The trigger pin at the bottom of the tube prevented the Mentos from falling into the bottle until you pulled the string attached to the pin. half a roll) in the test tube. (Gruber, 2019). Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. How do Coke and Mentos Work? - Medium This is a great topic for a science project. The secret is to turn your attention away from the spraying soda and concentrate on setting up an experiment where a single variable is isolated. Mentos Geyser Experiment - Mentos & Coke Experiment - The Lab Coke has a pH of 2.3 and it made intuitive sense that an acid-base reaction could explain the sudden explosion of sugar. This made the diameter of the candy too large to fit into the mouth of the soda bottle. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. It truly is the perfect chemistry kit for kids who want to explore. WebMentos and Diet Coke Experiment. All Rights Reserved. ), 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). Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. 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. Figure 1(c) is a magnified view of the edges of a salt grain, and Fig. Thats my final answer.. [3][11][12] In March 2002, Steve Spangler, a science educator, did the demonstration on KUSA-TV, an NBC affiliate, in Denver, Colorado. Load seven Mentos into your paper roll or yourGeyser Tubeand drop them into the soda and immediately record the data. Coke has a pH of 2.3 and it made intuitive sense that an acid-base reaction could explain the sudden explosion of sugar. Compare the contact angle results in Table V for pure water (=85), sugar water (=80), and aspartame dissolved in water (=77). 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. This phenomenon is an illustration of Henrys law given in Eq. [7][8] Experiments carried out at altitudes ranging from below sea level in Death Valley to the summit of Pikes Peak have demonstrated that the reaction works better at higher elevations. 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.). All of our results seem to contradict the aforementioned Mythbusters experiment. Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom. [10] When the pressure is released from a soda bottle upon opening it, dissolved carbon dioxide can escape into any tiny bubble located within the beverage. Dont forget to look back at the amazing eruption of soda. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. 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. The pits on the candy coating act as conduits for carbon dioxide bubbles that form immediately when the candy hits the soda, increasing its fizziness. Is the coke and Mentos reaction really a chemical reaction? The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released. Mentos and Coke Experiment How to Do It! Be sure that the soda bottles are all the same brand and type. Mentos & Soda Experiment Teaching Resources | TPT This will happen because the dissolved CO2 will provide the most nucleation sites to come out of the solution. The Hypothesis. After this, two interested scientists from the entertainment company EepyBird, Fritz Grobe and Stephen Voltz decided to post a Youtube video demonstrating this experiment and it went viral, gaining 120 million views. The simplest method is to let the unopened bottle sit in the sun for several hours. The scale bars represent the following lengths: (a) 2.0mm; (b) 100m, (c) 50m, and (d) 20m. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. Thus, adding Mentos candies to a carbonated beverage introduces millions of nucleation sites into the drink, which allows for degassing that is rapid enough to support a jet of foam out of a bottle. [15] Amazing Toys, Spangler's toy company, released the Geyser Tube toys in February 2007. Did what you hypothesize happen? What did you observe when you put Mentos candy into the soda bottle? 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. However, the importance of the presence of surfactants in the Mentos cannot be denied. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? What is the independent variable in the Mentos experiment? This is what happens when you combine 200 liters of Diet Coke and over 500 Mentos mints! SEM images of table salt, acquired with a beam energy of 5.0kV and a spot size of 5nm. 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. We found that the max amount of mentos with the Does the flavor of Mentos affect the explosion? This high school science fair project investigates if small changes in your diet alter the pH of your saliva. Notice how bubbles immediately form on the surface of the object. Many soda geyser-ologists believe that seven Mentos candies produce the highest shooting geyser. This easy at-home experiment is a great way to "see" science. The biggest challenge in the Mentos Geyser Experiment is finding a consistent way to drop the Mentos into the soda every time. Repeat the same procedure for the bottle of soda at room temperature and then again for the bottle of warm soda. The higher magnification images shown in Figs. Sample contact angle images for (a) deionized water, (b) deionized water with added aspartame, and (c) deionized water with added potassium benzoate. Learn all about the science of seeds and have fun getting your hands in the dirt. 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. ", "Orchestrated Chaos: A Mentos Tribute to Eepybird.com", About.com Chemistry page with instructions, "Watch Scientists Conduct the Mentos and Diet Coke Experiment at 14,000 Feet", "Diet Coke and Mentos: What is really behind this physical reaction? Dog Diets: Will a Dog Prefer Homemade Dog Food? Mentos Lab Report - Google Docs Teachers threaded the roll of Wintergreen LifeSavers onto a pipe cleaner as an easy way to drop all of the LifeSavers into the soda at the same time. 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. The Mythbusters team did a wonderful job of identifying the basic ingredients in this reaction. Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a Line up a row of 10 soda bottles against a brick wall. Before you get started, youll need to find a location suitable for the experiment. Make sure your scale is in place, whether youre measuring by counting bricks or using an alternative method. Part of the scientific method is making a prediction called a hypothesis. 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. Explore the science of building polymers by cross-linking long chains of molecules. Subtract the remaining amount of liquid from the original volume of the bottle to calculate the volume of the geyser. 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. This conclusion is also supported by the ingredients in the Mentos, none of which are basic: sugar, glucose syrup, hydrogenated coconut oil, gelatin, dextrin, natural flavor, corn starch, and gum arabic. In this case, were changing the number of Mentos dropped into each bottle, so everything else has to stay the same. 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). Also, the coating dissolves very rapidly in water, and so is not effective at preventing the growth of carbon dioxide bubbles. We found that the max amount of mentos with the largest Diet Coke and Mentos Write down what happened when you dropped the Mentos in the coke. Now, its time to run away. How does the temperature of the soda affect the height of the soda stream when Mentos are added to soda? 1 So the relatively small amount of caffeine in a 2 l bottle of Coke doesnt significantly affect the reaction. The Mentos And Coke Volcano Experiment. Try dropping an object, like a raisin or a piece of uncooked pasta, into a glass of soda. We put 4 mentos pieces into the bottle of diet coke. CYSF Retrieved from https://easyscienceforkids.com/diet-coke-and-mentos-video-for-kids/. MENTOS Copyright 2023 Education.com, Inc, a division of IXL Learning All Rights Reserved. What is the hypothesis for the Diet Coke and Mentos experiment? Mentos Experiment Mentos Eruption caused by mixing Diet Coke and Mentos, "Naperville students integral to classic TV bits, but will the fun continue? What happens when you drop Mentos in a bottle of coke? But it has nothing to do with the mint Mentos actual flavor. 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. Watch as they vanish right before your eyes in water as they grow. [21][29], Additional explanations for why diet sodas outperform regular sodas in this experiment have been proposed. Can I use clear bottom plates for fluorescence? If you continue to use this site we will assume that you are happy with it. Try placing the soda bottle next to the wall of a brick building, after getting permission from the buildings owner, of course. Set up three tests: warm soda, room temperature soda and cold soda. 4, and some of the AFM images are shown in Figs. Or, attach plastic piping or tubing to extend the openings neck. The activation energy for bubble nucleation (formation of bubbles) depends on where the bubble forms. The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres. To switch between accounts click on the account below. Learn more about how plants work with this cool celery experiment! Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. Mentos What is the independent variable in the Mentos experiment? What are the variables of the soda and Mentos experiment? To use the Mentos Geyser for a science fair project, youll to turn this cool science activity into a real science experiment. The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. How long do you cook jerky in open country dehydrator? Of these three highly eruptive reactions, the Wint-o-Green reaction lasted the longest and lost a comparable amount of mass to the others, but traveled a much shorter distance than the Fruit and Mint Mentos reactions. A search on Google for Diet Coke and Mentos will return millions of hits, and YouTube has many home videos of this reaction. What type of chemical reaction is Coke and Mentos? Regular Coke does not work with Mentos because the Diet Coke uses Aspartame instead of sugar, which regular Coke uses. 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. This was demonstrated in an experiment that tested 15 types of carbonated beverages with Mentos. To add insult to injury, she did it two more times. Diet Coke and Mentos Originally it was thought that the colossal fountain of soda spraying out of the bottle was caused by the caffeine in Coke. 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. There are two safe ways to warm the other bottle of soda. The carbon dioxide attaches throughout the bead, increasing the amount of time over which the reaction occurs. Mentos Geyser Experiment Mentos & Coke Experiment I also posted the video on a new online video-sharing site called YouTube (YouTube was only seven months old at that time). 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. Coke Spurting Science: Erupting Diet Coke with Mentos. Stir up some enthusiasm for experimentation with this candy-cracking science 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. What did you observe after you put Mentos candies into the soda bottle? What effect does temperature have on the height of the geyser? Mentos and Coke Experiment How to Do It! [Full Guide] - Cool Muir, H. (2008, June 12). Stack the Mentos candies (approx. Hypothesis: The larger the number of mentos, and the warmer the temperature of the soda, the higher the reaction will be. QUESTIONS: 1. Children will enjoy this hilarious story and use their hands to mix up a batch of Instant Worms. 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. The Diet The dependent variable was the height of the rise of Coca-Cola. View the Mentos Geyser Experiment here! Once your Mentos are lined up and ready to drop, its time for the fun to begin. 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. The measured contact angles and minimum works for bubble formation are given in Table IV. 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 Thats why its called a Baby Soda Bottle! 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.). 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 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. Lets start with seven Mentos for our first attempt. Each mint has thousands of tiny pits all over its surface. So when a bottle of soda is opened, the partial pressure drops, and the molar concentration of the gas must also drop, which is why sodas go flat over time after they are opened. Because Mentos are heavy and sink to the bottom of the bottle, the gas released by the Mentos pushes the soda up and out of the bottle in an incredible and amazing blast. While a Mentos candy contains millions of cavities, it is likely that only about 100,000 cavities actively nucleate bubbles on any single Mentos candy placed in a carbonated beverage.[19][25]. You want the bottle to be stable before conducting the experiment. Test your dog's preferred diet in this fun experiment. Which is the best 150 Ah inverter battery? As strange as it might sound, the Mentos Geyser Experiment never actually started out using Mentos chewy mints. Slight adjustments to the positioning of the spout on the bottle or small adjustments to the position of the bottle in the holder can cause the angle of the spray to change, which can affect the sprays range by several feet. Coke And Mentos Experiment Free Essay Example - PaperAp.com Tobin, Declan. Lee Marek and Mareks Kid Scientists performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. The experiment became a subject of the television show MythBusters in 2006. 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. What is the hypothesis of Mentos and soda? 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. 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. The quantitative roughness information detailed in Table V was taken from this image. But there was one added bonus: the restricted hole at the top of the plastic tube helped to build up more pressure in the bottle and launched the soda up to 30 feet into the air! [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. ERIC - EJ1240905 - Kinetic Modeling of and Effect of Candy [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. This low temperature allows the maximum amount of carbon dioxide to dissolve into the soda, keeping the carbonation levels as high as possible. Using any more than seven Mentos mints is just a waste, according to these soda-soaked science enthusiasts. Why do different sodas react differently to Mentos? Prior to heating, the bottle was opened to release some of the internal pressure, and then closed again. Average horizontal distance traveled by the spray during the reaction.
