Once the geyser stops, measure how much liquid is left inside. To the naked eye, Fruit Mentos are shinier than Mint Mentos, and therefore should be smoother. The Mentos mints then dropped into the soda. The video was titled Extreme Diet Coke & Mentos Experiments. This means that there is a whole lot of carbon dioxide gas just waiting to escape the liquid in the form of bubbles. These ingredients accelerate the foaming action of the soda very quickly, causing the infamous explosion. ), 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 more mentos you put in a bottle of pop does not necessarily mean a larger explosion. We use cookies to ensure that we give you the best experience on our website. Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a ", "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? Place the index card and candies over the mouth of the bottle. The carbon dioxide attaches throughout the bead, increasing the amount of time over which the reaction occurs. It comes with six fun experiments, a test tube rack, fizzing tablet and vegetable oil chemicals to play around with. 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. Carbonated sodas contain elevated levels of carbon dioxide under pressure. 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. 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. 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. This low temperature allows the maximum amount of carbon dioxide to dissolve into the soda, keeping the carbonation levels as high as possible. Gruber, B. This easy at-home experiment is a great way to "see" science. This all boils down to the presence (or lack thereof) of sugar. In this project, you'll create Oersted's experiment, which relates to how electric currents create magnetic fields. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. [30] However, any carbonated beverage will work. What is inside Mentos and cola that reacts with each other causing the eruption? Watch as they vanish right before your eyes in water as they grow. Fast-moving mentos create larger explosions while slow, powdered mentos create tiny ones (Muir, 2008). 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. You could use abeakeror agraduated cylinderto measure the remaining soda in milliliters. However, is one better for use during an experiment? If spectators were watching your exploits, someone is bound to yell out, Do it again! Thats exactly what youre going to do. Cover the opening of the test tube with an index card or similar slim, small paper. It is difficult to find beverages containing aspartame that do not contain a preservative such as potassium benzoate. The AFM rms roughness measurements are given in Table V. The SEM images of some of the samples are shown in Figs. Also, the coating dissolves very rapidly in water, and so is not effective at preventing the growth of carbon dioxide bubbles. What happens if you combine soda and Mentos? Did what you hypothesize happen? 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. In fact, its not really a reaction at all or at least its a physical reaction rather than a chemical one. Just mix the two liquids and get more than 300 feet of Instant Worms. 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. 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. 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.]. [9][10], In the 1910s, Wint-O-Green Life Savers were used to create soda geysers. Set up three tests: warm soda, room temperature soda and cold soda. Lee Marek and "Marek's Kid Scientists" were the first to publicly demonstrate the experiment on the Late Show with David Letterman in 1999. Adding salt to soda also causes it to foam because thousands of little bubbles form on the surface of each grain of salt. [15] Amazing Toys, Spangler's toy company, released the Geyser Tube toys in February 2007. Lee Marek and Mareks Kid Scientists performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. 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. As strange as it might sound, the Mentos Geyser Experiment never actually started out using Mentos chewy mints. Based on these SEM images and our inability to image the samples in the AFM due to the limits on our z range, we assume that these samples have a roughness greater than those reported in Table V. Although these samples are rough, the fall times through the bottle, the duration of the reaction, and the lack of a surfactant contributed to a less impressive eruption for these samples. 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. 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 uncertainties are approximately 10%. (Gruber, 2019). 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. This makes the cleanup process after the experiment easier, and less gross, as nobody would want to be all covered in sugary goop, especially on a hot summer day! Contact mode AFM image of Wint-o-Green Lifesaver. 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. We found that the max amount of mentos with the . The basic science of the Coke and Mentos reaction is fairly straightforward. Record the temperature. The other bottles were heated in a water bath on a hot plate for approximately 1020min. How Does Diet Affect Your Body Temperature? The mint Mentos mixed with diet coke usually explodes the longer and higher while fruit Mentos has a more delayed and less impressive reaction. The Hypothesis. 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. 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. This will work on any drink that is carbonated. The color combined with the small size of the salt grains made it too difficult to see, and therefore difficult to determine the time of fall for the table salt. He would like to know why does the shape and size of the mentos affect the outcome of the project. Also thanks to my undergraduate summer research assistants for their hard work, including A.J. SEM images of Mint Mentos [(a) and (c)] and Fruit Mentos with a candy coating [(b) and (d)]. What effect does temperature have on the height of the geyser? Part of the scientific method is making a prediction called a hypothesis. This is the experiments variable. Given the ingredients listed on Diet Coke, there is more aspartame than potassium benzoate in Diet Coke per unit volume. Try dropping an object, like a raisin or a piece of uncooked pasta, into a glass of soda. Science project. And you may not have a friend for a day or two until they forgive you. The physical characteristics of Mentos (surface roughness) have the effect of drastically reducing the activation energy for carbon dioxide bubble formation so that the nucleation rate becomes exceedingly high. 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. Make sure the candies are in line with the mouth of the bottle. American Journal of Physics 1 June 2008; 76 (6): 551557. Unfortunately, Kim got so caught up in the fun that she forgot to do both and got soaked in Diet Coke on live television! The pH of the diet Coke prior to the reaction was 3.0, and the pH of the diet Coke after the mint Mentos reaction was also 3.0. This study began as a project for physics majors enrolled in a sophomore level physics lab course. Figure 1(b) shows rough patches and nooks and crannies in the salt, which are also excellent growth sites. Invert the test tube, holding the cover in place. The reaction happens fast, so dont have your face over the bottle. We found that the Diet CokeMint Mentos reaction lasted 3.8s, the Diet CokeFruit Mentos reaction lasted 3.6s, and the Diet CokeWint-o-Green reaction lasted 4.9s. There are two safe ways to warm the other bottle of soda. You can also place the bottle of unopened soda in a bucket of warm water. Carbonated beverages are full of dissolved carbon dioxide gas (CO2) which makes bonds with the water molecules. 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? American Crystallographic Association, Inc. AVS: Science and Technology of Materials, Interfaces and Processing, www.stevespanglerscience.com/experiment/00000109, Paragliders' launch trajectory is universal, On the bifurcation behavior of a folded notebook page, Rosalind Franklin's X-ray photo of DNA as an undergraduate optical diffraction experiment, Introducing quantum mechanics through its historical roots: The hydrogen Rydberg atom viewed through the lens of the old quantum theory, The discovery of a supermassive black hole at the center of the Milky Way galaxy, Sensory evaluation and electronic tongue analysis for sweetener recognition in coke drinks. You want the bottle to be stable before conducting the experiment. https://easyscienceforkids.com/diet-coke-and-mentos-video-for-kids/. Originally it was thought that the colossal fountain of soda spraying out of the bottle was caused by the caffeine in Coke. Write down what happened when you dropped the Mentos in the coke. For each of the samples a (10m)2 image was acquired, and the root-mean-square (rms) roughness in the image was reported. We showed the importance of sample roughness by comparing SEM and AFM images of the samples to the explosive power of the reaction. 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. Open the soda and place the index card over the bottle opening. It is an excellent way for children to see gas in action and is a great activity to teach Soda is made of sugar or artificial sweetener, flavoring, water and preservatives. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. If you want to examine the volume of the geyser, note the volume of a full bottle of soda before you drop the Mentos into it. To add insult to injury, she did it two more times. Learn all about the secrets that make seeds grow and the conservation power of Water Jelly Crystals. Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water. There really arent that many supplies you need to make a mentos and coke volcano. As mentioned earlier in the article, using either diet coke or regular coke alongside mentos can produce a spewing geyser of carbonation bubbles. This experiment can be visually displayed with photos or videos of the event and a graph of the tables results. WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. The warmer the liquid, thelessgas can be dissolved in that liquid. 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 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 Mythbusters team did a wonderful job of identifying the basic ingredients in this reaction. It truly is the perfect chemistry kit for kids who want to explore. There are two major reasons for this discrepancy. Next, some thought that the pH of the liquid was responsible for the vigorous reaction. The demo went from relative obscurity to an internet sensation! Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. 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 coating of the Mentos contains gum arabic, a surfactant that reduces the surface tension of water. However, the importance of the presence of surfactants in the Mentos cannot be denied. Does Colorado have a defensive driving course? Today Room 1 and 5 did a science experiment together. Make comparisons, create a chart with your data and draw some conclusions. The average distance traveled by the sodas spray during the explosion is given in Table II. The scientific method is an important way scientists make observations and come to conclusions. Prior to heating, the bottle was opened to release some of the internal pressure, and then closed again. Longer lasting carbonation bubbles, therefore, increases the height of the bubble geyser that forms a mentos and coke reaction. 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. An impressive acid-base reaction can be generated by adding baking soda to Diet Coke. How long do you cook jerky in open country dehydrator? 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. Why does the reaction happen? 5 Research Drive, Suite 150Shelton, CT 06484. How does the temperature of the soda affect the height of the soda stream when Mentos are added to soda? Conjure a magical genie inside a root beer bottle, awaken a thirsty ghost, use your amazing brainpower to read minds, and more. 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. Explore the science of building polymers by cross-linking long chains of molecules. It comes with six fun experiments, a test tube rack, fizzing tablet and vegetable oil chemicals to play around with. Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. So aspartame causes the most mass lost. Place the soda bottle outside in and area that can get dirty. The question in the hypothesis was answered too, with the answer being no. 8:30 am 5:00 pm (MST), Steve Spangler Science 2008 American Association of Physics Teachers. Be sure that the soda bottles are all the same brand and type. Each time, she was covered in more soda until her once-pink dress was now more Coke-colored than pink! 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?"
