conclusion for coke and mentos experiment

The students designed the experiment, did almost all of the data acquisition, and disseminated their results in a poster session at our spring Research and Creative Endeavors Day at Appalachian State University. Overall I expect the Pepsi and Mentos to create a fountain like reaction. 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. Only one trial was performed for each temperature. Monday Friday Today Room 1 and 5 did a science experiment together. Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. Notice how bubbles immediately form on the surface of the object. What is the fastest way to level up pickpocketing in Skyrim? WebSince which invention of cola, the gegner between Pepsi and Coca-Cola (i.e., Coke) has had in existence. Unscrew soda and put safety goggles on. With 5 or 6 mentos the explosion went only 330 and 310 cm high. This bubbling process is called nucleation. Next, some thought that the pH of the liquid was responsible for the vigorous reaction. The Mentos candy gelatin and gum arabic create an energy that breaks the surface tension of the soda. Carbon dioxide creates the bubbles in soda. From our results in Tables I and II we see that the rock salt performance far exceeds the table salt performance, even though the surface area to volume ratio (and hence the number of bubble growth sites per gram) is larger for the table salt. The 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 did you observe after you put Mentos candies into the soda bottle? I also posted the video on a new online video-sharing site called YouTube (YouTube was only seven months old at that time). The results in Table II are comparable to results from previous studies.3 Two to four trials were done for each sample-soda combination. Science of Mentos-Diet Coke explosions explained. If the growth of carbon dioxide bubbles on the sample takes place at the bottom of the bottle, then the bubbles formed will detach from the sample and rise up the bottle. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in the water.

(4)P is the partial pressure of the gas above the liquid, K is a parameter, and c is the molar concentration of the gas. For example, it has been suggested that the higher viscosity of regular sodas as compared to diet sodas could inhibit the formation of the fountain in regular sodas, leading to shorter fountains. [22] The foaming is aided by the presence of food additives such as potassium benzoate, aspartame, sugars, and flavorings in Diet Coke,[20] all of which influence the degree to which water can foam. Pepper has the strongest reaction. This hands-on experiment is easy to do and simply involves dropping Mentos into a bottle of diet soda and running away. As the molecules move faster, they diffuse out of the liquid, leaving less gas dissolved in that liquid. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. We found that the max amount of mentos with the largest Their explanation is this process called nucleation. 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 tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. Regular Coke does not work with Mentos because the Diet Coke uses Aspartame instead of sugar, which regular Coke uses. [10][23][24] Because there usually are very few such pre-existing bubbles, the degassing process is slow. Aspiring Botanists, and even young gardeners, will get excited about science with this hands-on kit. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. Hypothesis: The larger the number of mentos, and the warmer the temperature of the soda, the higher the reaction will be. Coke has a pH of 2.3 and it made intuitive sense that an acid-base reaction could explain the sudden explosion of sugar. 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 Rights Reserved. Thank you so much. The thing that makes soda bubbly is invisible carbon dioxide, which is pumped into bottles at the factory using lots and lots of pressure. Please follow us on Medium and on Instagram, thanks! How can I download Tekken 7 on Windows 7? http://www.eepybird.com/featured-video/coke-and-mentos-featured-video/science-of-coke-mentos/. The blend of Coke Zero and Mentos just works out the strongest. Toll Free: 800-223-9080 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. The results for the trials with varying temperature are given in Table III. And you may not have a friend for a day or two until they forgive you. 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. The average amount of mass lost for the various combinations of soda and samples is given in Table I. 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. Then, make comparisons, create a chart with your data and draw your conclusions. View the Mentos Geyser Experiment here! The other bottles were heated in a water bath on a hot plate for approximately 1020min. 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. Although this conclusion seems to refute the claims made by the Mythbusters, remember that in their experiments, Jamie added enough caffeine to kill you to the seltzer water. A more dramatic effect is the rate of the reaction. Pull the index card away swiftly, dropping the candies into the soda. Since diet sodas lack the sugar that regular ones do, it has lower viscosity and surface tension. Compare these times to the mass lost and distance traveled results in Tables I and II. Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. 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. This will count as your control group. The Mentos And Coke Volcano Experiment. Observe and explain the Mentos and Diet Coke experiment. Start by opening the cold bottle and dipping the thermometer into the soda. Why does the reaction happen? 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. If spectators were watching your exploits, someone is bound to yell out, Do it again! Thats exactly what youre going to do. Fast-moving mentos create larger explosions while slow, powdered mentos create tiny ones (Muir, 2008). Superabsorbent giant growing polymer beads that absorb 150 times their weight in water! We even played with ways to use the Geyser Tube to trigger multiple soda geysers in a method similar to a Rube Goldberg machine. Explore the science of building polymers by cross-linking long chains of molecules. You could use abeakeror agraduated cylinderto measure the remaining soda in milliliters. Figure 1(c) is a magnified view of the edges of a salt grain, and Fig. The answer is yes. This low temperature allows the maximum amount of carbon dioxide to dissolve into the soda, keeping the carbonation levels as high as possible. WebCONCLUSIONS: ( Do you accept or reject your hypothesis, and why or why not) You and your partner will share your experiment with the class. eleanorrigby-movie.com 2023 This is the experiments variable. The biggest challenge in the Mentos Geyser Experiment is finding a consistent way to drop the Mentos into the soda every time. Conjure a magical genie inside a root beer bottle, awaken a thirsty ghost, use your amazing brainpower to read minds, and more. WebThis is a fun and exciting experiment designed for 3rd-6th graders. 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. These growth sites are not all on the surface of the bead, and hence the Diet Coke has to soak into the bead through the pores. A search on Google for Diet Coke and Mentos will return millions of hits, and YouTube has many home videos of this reaction. All of the Coca-Cola products had the same expiration date, so the level of carbonation in each 2l bottle should be similar. The question in the hypothesis was answered too, with the answer being no. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. If you shake a bottle or can of soda, some of the gas comes out of the solution and the bubbles cling to the inside walls of the container thanks to the tiny pits and imperfections on the inner surface of the bottle called nucleation sites. 4, and some of the AFM images are shown in Figs. The scale bar for (a) is 100m and for (b) is 20m. While I had performed variations of the Mentos Geyser Experiment on television many times from 2001 to 2004, my performance of the demo in the backyard of Denvers NBC affiliate KUSA-TV in September of 2005 proved to be the tipping point. The Mentos mints then dropped into the soda. Then, observe, record and report the results. 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.). A 10% difference is comparable to the uncertainty in our experiments, and hence it is difficult to observe significant differences in the results for Diet Coke compared to Caffeine Free Diet Coke. Its true that putting Mentos into a bottle of Coke will cause an impressive geyser of soda to erupt from the bottle. What are the independent and dependent variables in Coke and Mentos? What is the dependent variable of Coke and Mentos? Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. Lets start with seven Mentos for our first attempt. The Amazing Scientist Chemistry Kit is designed to get your young scientist interested in chemistry. students used this simple device to monitor the kinetics of Because Type IV nucleation sites (such as found on Mentos) allow the reaction to proceed with substantially lower activation energy, Mentos candies can appropriately be considered a catalyst of the process. Part of the scientific method is making a prediction called a hypothesis. We constructed a bottle stand (roughly 10 off vertical) to prevent the bottles from tipping over and the liquid from falling back into the bottle. 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. Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom. Can I use clear bottom plates for fluorescence? Warning - you are about to disable cookies. The quantitative roughness information detailed in Table V was taken from this image. Today, all of that will be answered in our article down below! So aspartame causes the most mass lost. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.
