conclusion for coke and mentos experiment

Now remove the index card and let candies fall in and step away from the Mentos and coke volcano. To compare two systems, we calculate a ratio of the works required for bubble formation: We used this technique to compare the work required for formation of a bubble in deionized water to other liquids, as summarized in Table IV. Since diet sodas lack the sugar that regular ones do, it has lower viscosity and surface tension. [1][14][17] Tonya Coffey, a physicist at Appalachian State University, suggested that aspartame in diet drinks lowers the surface tension in the water and causes a bigger reaction, but that caffeine does not accelerate the process. 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. Figure 1(c) is a magnified view of the edges of a salt grain, and Fig. Why does Diet Coke and Mentos explode more than regular Coke? Observe the eruptionheight, trajectory, duration, etc. In the Mentos and Diet Coke experiment, Arnold was trying to prove that the Diet Coke would explode if he put 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. Never use a stove or a microwave to heat a bottle of soda. Why Do Flight Attendants Hate Serving This Drink to Passengers in Flight? The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. 2.) The Diet Does the amount of Mentos affect the height of the explosion? 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. Position the bottle on the ground so that it will not tip over. Load seven Mentos into your paper roll or yourGeyser Tubeand drop them into the soda and immediately record the data. height 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.1 So the relatively small amount of caffeine in a 2l bottle of Coke doesnt significantly affect the reaction. 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). Make comparisons, create a chart with your data and draw some conclusions. Repeat the same procedure for the bottle of soda at room temperature and then again for the bottle of warm soda. It needs to be wide enough to use as loader for the Mentos. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual. 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. 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. Start by opening the cold bottle and dipping the thermometer into the soda. Try placing the soda bottle next to the wall of a brick building, after getting permission from the buildings owner, of course. 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. This experiment investigates if small changes in your diet can alter your basal body temperature. WebSince which invention of cola, the gegner between Pepsi and Coca-Cola (i.e., Coke) has had in existence. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos, like a roll of coins. This study began as a project for physics majors enrolled in a sophomore level physics lab course. 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. 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. Prior to heating, the bottle was opened to release some of the internal pressure, and then closed again. Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. Did a child really die from combining Mentos and Coca-Cola? Subtract the remaining amount of liquid from the original volume of the bottle to calculate the volume of the geyser. What is inside Mentos and Cola that reacts with each other causing the eruption? If you decide to create an account with us in the future, you will need to enable cookies before doing so. 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. 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.[1][2]. Regular soda becomes a sticky mess because it contains sugar, while diet soda uses artificial sweeteners instead of sugar, so its not as sticky. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. WebCONCLUSIONS: ( Do you accept or reject your hypothesis, and why or why not) You and your partner will share your experiment with the class. Today Room 1 and 5 did a science experiment together. 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. 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. Unfortunately, Kim got so caught up in the fun that she forgot to do both and got soaked in Diet Coke on live television! This is because the warm air would have a greater volume and would exert more pressure, which would force the soda to a higher height. . Carbonated sodas contain elevated levels of carbon dioxide under pressure. 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. (As discussed, part of the reason that the Wint-o-Green reaction took more time is due to the increased fall times.) Thats my final answer.. SEM images of table salt, acquired with a beam energy of 5.0kV and a spot size of 5nm. The colder the liquid, themoregas can be dissolved in that liquid. Coke possesses been which preferred mark through all other coke, spite one preference for Pepsi in blind taste tests. Also, the coating dissolves very rapidly in water, and so is not effective at preventing the growth of carbon dioxide bubbles. Making science accessible and fun for youth. Due to the small amount of caffeine in a 2l bottle of Diet Coke, we do not agree that the caffeine in Diet Coke contributes significantly to the reaction. View the Mentos Geyser Experiment here! The demo went from relative obscurity to an internet sensation! Spanish-English dictionary, translator, and learning, Marketplace for millions of educator-created resources. The Mentos And Coke Volcano Experiment. 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. 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. We put 4 mentos pieces into the bottle of diet coke. However, a change in surface roughness might also occur and affect the results when the Mentos is crushed. As mentioned earlier in the article, using either diet coke or regular coke alongside mentos can produce a spewing geyser of carbonation bubbles. WebKids TV Yenu and Sanu is home to gaining knowledge & entertain toddlers. The average distance traveled by the sodas spray during the explosion is given in Table II. Soda is made of sugar or artificial sweetener, flavoring, water and preservatives. Steve Spanglers Geyser Tube toy (optional .
