conclusion for coke and mentos experiment

Soda is made of sugar or artificial sweetener, flavoring, water and preservatives. The basic science of the Coke and Mentos reaction is fairly straightforward. You want the candies going in the bottle and not falling over the side. This study began as a project for physics majors enrolled in a sophomore level physics lab course. Test your dog's preferred diet in this fun experiment. 5 and 6. Our AFM measurements show that the rms roughness of the Fruit and Mint Mentos surfaces are comparable (see Table V). Carbonated beverages are full of dissolved carbon dioxide gas (CO2) which makes bonds with the water molecules. 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. Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. 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. How many protons and electrons are present in Ba2+? Its time to put your favorite soda to the test in this fun experiment. This means that there is a whole lot of carbon dioxide gas just waiting to escape the liquid in the form of bubbles. 4, and some of the AFM images are shown in Figs. WebPut 5 room temp Mint Mentos in a geyser tube. Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. Mentos and Coke Experiment How to Do It! Thats my final answer.. 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. A more dramatic effect is the rate of the reaction. SEM images of playground sand acquired at a beam energy of 20kV and a spot size of 5.0nm. Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. Learn all about the science of seeds and have fun getting your hands in the dirt. It is clear from Table V that the roughness of the sample is a major contributor to the explosiveness of the reaction. 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. Something else to consider about diet sodas is that they tend to be less sticky when released out in the open. 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. [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 video was titled Extreme Diet Coke & Mentos Experiments. 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. What female country singers were on American Idol? This was the original inspiration behind the Geyser Tube. The contestant ended up doing really well, going all the way to the $250,000 question; however, he walked away with $125,000. Instead of Mentos mints candy, however, they used a roll of Wintergreen LifeSavers and a pipe cleaner. The experiment became a subject of the television show MythBusters in 2006. Then, make comparisons, create a chart with your data and draw your conclusions. It needs to be wide enough to use as loader for the Mentos. 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. Record your observations in a logbook. Dont forget to look back at the amazing eruption of soda. [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. How does the flavor of Mentos affect the explosion? Copyright 2023 Education.com, Inc, a division of IXL Learning All Rights Reserved. Dont miss our other super-fun and hands-on experiments in our huge online experiment library! The bottom line was that we needed to find a way to standardize the drop of those Mentos mints. (2021). 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. Experiment with your sense of taste and your sense of smell with this simple 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. WebSince which invention of cola, the gegner between Pepsi and Coca-Cola (i.e., Coke) has had in existence. 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. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. Watch as they vanish right before your eyes in water as they grow. Repeat steps 4-6 for Diet Dog Diets: Will a Dog Prefer Homemade Dog Food? Spurting Science: Erupting Diet Coke with Mentos. 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. 2008 American Association of Physics Teachers. 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. To get the best results in a science experiment, you will need to standardize the test conditions as much as possible. https://www.scientificamerican.com/article/bring-science-home-coke-mentos/. This chemistry science kit includes activities for solo and group experiments, making it a fantastic addition to your classroom or for fun at home. For the reaction between Diet Coke and the molecular sieve beads, the lower limit on the duration of this reaction was 12s, a much longer time than all of the other reactions. The Diet Coke and Mentos reaction is a fun demonstration in chemistry and physics classes of many important concepts in thermodynamics, fluid dynamics, surface science, and the physics of explosions. Cover the opening of the test tube with an index card or similar slim, small paper. https://doi.org/10.1119/1.2888546. Does the amount of Mentos affect the height of the explosion? WebFInally, the average height of the hot bottles' geysers was 19.5 inches and was the greatest. Note that the contact angles for Diet Coke and Caffeine Free Diet Coke are not very different. Warm soda tends to fizz much more than cold soda because of the solubility of gases in liquids. Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. Youll need lots of soda and Mentos, as well as a few friends to help record all of the data. Each bottle will receive a different number of Mentos. What properties do coke and mentos have that enable them to react so vigorously with each other? This must been coined as the Pepsi Paradox. Its true that putting Mentos into a bottle of Coke will cause an impressive geyser of soda to erupt from the bottle. 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. The uncertainty is approximately 10%. Based on the Data, the hypothesis of my experiment (If the Diet Coke is heated, then it will have the highest geyser, because the atoms will be moving more rapidly and act as a catalyst) was proven to be correct. Given the ingredients listed on Diet Coke, there is more aspartame than potassium benzoate in Diet Coke per unit volume. The colder the liquid, themoregas can be dissolved in that liquid. Regular soda becomes a sticky mess because it contains sugar, while diet soda uses artificial sweeteners instead of sugar, so its not as sticky. 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. [16] In October 2010, a Guinness World Record of 2,865 simultaneous geysers was set at an event organized by Perfetti Van Melle at the SM Mall of Asia Complex, in Manila, Philippines. [Full Guide] - Cool Figure 1(b) shows rough patches and nooks and crannies in the salt, which are also excellent growth sites. 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. What do your results reveal about the effect that the number of Mentos has on the height of the geyser? 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. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. It truly is the perfect chemistry kit for kids who want to explore. 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 thing that makes soda bubbly is invisible carbon dioxide, which is pumped into bottles at the factory using lots and lots of pressure. This hands-on experiment is easy to do and simply involves dropping Mentos into a bottle of diet soda and running away. The Mentos mints then dropped into the soda. This procedure prevented the explosion of the bottle during heating, but the early release of some of the carbon dioxide gas may have caused these reactions to be less explosive than the cold or room temperature trials. 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. View the Mentos Geyser Experiment here! Quantitative Observation The AFM rms roughness measurements are given in Table V. The SEM images of some of the samples are shown in Figs. When we drop the Mentos in the heated Diet Coke, the system moves toward equilibrium by liberating the excess carbon dioxide from the solution via the explosive reaction. 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. There really arent that many supplies you need to make a mentos and coke volcano. Compare the contact angle results in Table V for pure water (=85), sugar water (=80), and aspartame dissolved in water (=77). [19], While Diet Coke and Mentos are the most common way to make a soda geyser, they are not the only options. In colder liquids, the gas molecules move very slowly, causing them to diffuse out of the solution much more slowly, leaving more gas in the solution. No matter which brand of soda you tested, the warm bottle probably produced the highest shooting geyser. The potassium benzoate and the aspartame are active ingredients in the Mint MentosDiet Coke reaction, but the aspartame likely contributes more to the reaction. This bread mold experiment will help your child learn about mold, and he'll develop important hypothesis-making and experiment-designing skills. Before you get started, youll need to find a location suitable for the experiment. The Diet Coke and Mentos experiment results from an increased rate of nucleation. 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. Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. 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. [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. Be prepared: the eruption happens quickly, so back up fast! What happens when you mix Diet Coke and Mentos? Part of his assignment Is to ask a professional about his experiment. Superabsorbent giant growing polymer beads that absorb 150 times their weight in water! Does the amount of Mentos affect the height of the explosion? Do a little bit of research about the ingredients of Mentos and soda. 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. It is very high for bubbles that form in the liquid itself (homogeneous nucleation), and much lower if bubble growth occurs within tiny bubbles trapped in some other surface (heterogeneous nucleation). In Table IV we assumed that LV was reduced by 5% for the second system compared to the deionized water (system 1). 2.) I must admit, however, that even with the Baby Soda Bottle method, the results were not very consistent. Adding salt to soda also causes it to foam because thousands of little bubbles form on the surface of each grain of salt. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? 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. The quantitative roughness information detailed in Table V was taken from this image. Why does the coke react to Mentos? WebThe Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. In the Mythbusters episode1 a Mint Mentos and a brightly colored Mentos were dropped into Diet Coke, and although the Mint Mentos caused the expected eruption, the brightly colored Mentos did almost nothing. Why Do Flight Attendants Hate Serving This Drink to Passengers in Flight? What is a good hypothesis for Mentos and Diet Coke? Write down what happened when you dropped the Mentos in the coke. I also posted the video on a new online video-sharing site called YouTube (YouTube was only seven months old at that time). Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom.
