conclusion for coke and mentos experiment

Using any more than seven Mentos mints is just a waste, according to these soda-soaked science enthusiasts. State briefly what you tried, what were your results, and what you might do differently next time. However, a change in surface roughness might also occur and affect the results when the Mentos is crushed. The variable could be something like the number of mentos dropped into the bottle, the flavor of diet soda, the size of the bottle, or the temperature of the soda. The average amount of mass lost for the various combinations of soda and samples is given in Table I. To ensure accurate distance measurements and to extract other useful information, a video was made of the reactions, and marker flags were placed every half foot on the level ground, up to a distance of 25ft away from the bottle stand. WebWhen Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. Hypothesis: If a certain amount of Mentos are dropped into a container of soda, then the container with the most Mentos dropped into it will produce the most CO2 at the fastest rate. This was the original inspiration behind the Geyser Tube. To get the best results in a science experiment, you will need to standardize the test conditions as much as possible. What are the variables of the soda and Mentos experiment? Lee Marek and Mareks Kid Scientists performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. This phenomenon is an illustration of Henrys law given in Eq. 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. Easy Science for Kids. 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. 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 It doesnt matter what your variable is, it just has to be one concrete thing that you can change. What happens if you combine soda and Mentos? (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. Is the coke and Mentos reaction really a chemical reaction? To the naked eye, Fruit Mentos are shinier than Mint Mentos, and therefore should be smoother. The question in the hypothesis was answered too, with the answer being no. 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.

Pull the index card away swiftly, dropping the candies into the soda. 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. Today Room 1 and 5 did a science experiment together. It truly is the perfect chemistry kit for kids who want to explore. [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. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. The Wint-o-Green Lifesavers are rougher than the Mentos by a factor of 5, but the mass lost during these reactions is comparable. What is a good hypothesis for Mentos and Diet Coke? Record your observations in a logbook. Place one bottle in the refrigerator and let it sit there overnight. but highly recommended! (4) next and Le Chateliers principle.6. 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. Given the ingredients listed on Diet Coke, there is more aspartame than potassium benzoate in Diet Coke per unit volume. [Full Guide] - Cool But when the gum arabic was injected into the middle of the bottle, no mass was lost. These ready-made bubbles (which are nucleation sites) exist in things such as tiny fibers or non-wettable crevices on the sides of the bottle. Now its time to actually run the experiment,but first,we need to make a hypothesis. Can I use clear bottom plates for fluorescence? [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. This bread mold experiment will help your child learn about mold, and he'll develop important hypothesis-making and experiment-designing skills. WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. As they say, the rest is history. Make comparisons, create a chart with your data and draw some conclusions. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle's base. Subtract the remaining amount of liquid from the original volume of the bottle to calculate the volume of the geyser. Originally it was thought that the colossal fountain of soda spraying out of the bottle was caused by the caffeine in Coke. A one gallon bucket containing test tubes of over 10 Spangler Labs originals, Features favorites like Insta-Snow, Energy Beads, Jelly Marbles, & Magic Sand. 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. The mass 41020g was lost from the aspartameseltzer water mixture and 36020g of mass was lost from the potassium benzoateseltzer water mixture. You want the candies going in the bottle and not falling over the side. How long do you cook jerky in open country dehydrator? 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. In addition to the six outlined experiments, weve included suggestions for further fun, giving your future chemist more opportunities to learn and grow. 2023 Cool Kid Facts. 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. Everyone found their own method for quickly dropping the Mentos into the soda. The blend of Coke Zero and Mentos just works out the strongest. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. What do your results reveal about the effect that the number of Mentos has on the height of the geyser? However, the importance of the presence of surfactants in the Mentos cannot be denied. We even played with ways to use the Geyser Tube to trigger multiple soda geysers in a method similar to a Rube Goldberg machine. Never use a stove or a microwave to heat a bottle of soda. Put the index card on top of the tube loader and turn the tube upside down. 4, and some of the AFM images are shown in Figs. Place the soda bottle outside in and area that can get dirty. 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. The independent variable was the altering of each Mento. Grobe, F., & Voltz, S. The Science of Coke and Mentos. Stir up some enthusiasm for experimentation with this candy-cracking science experiment! Everyone wants to know how many Mentos make the highest shooting geyser. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. What is the aim of the Coke and Mentos experiment? Place the second bottle in a place where it will reach room temperature overnight. They cited the gum arabic and gelatin in the Mentos, and the caffeine, potassium benzoate, and aspartame in Diet Coke as the main contributors to the explosive reaction. However, the larger rock salt pellets fall quickly to the bottom of the 2l bottle, while the much smaller table salt grains fall more slowly due to their smaller weight and size. There is not always a direct correlation between the mass lost and the distance traveled for the reactions. Quantitative Observation You might need to put down something flat, like a small piece of wood, to hold it up. 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. . Contact angle measurements were made by placing small drops of the liquid solutions on a flat polycarbonate surface, photographing the drops, and measuring the contact angles from the photographs (see Fig. Then, make comparisons, create a chart with your data and draw your conclusions. The quantitative roughness information detailed in Table V was taken from this image.

The blend of Coke Zero and Mentos just works out the strongest. 1 So the relatively small amount of caffeine in a 2 l bottle of Coke doesnt significantly affect the reaction. The diet coke erupted like a volcano. Buddies, S. (2012, June 14). This is an urban myth. This activity is probably best done outside in the middle of a field or on a huge lawn where a little bit of mess wont be a big deal. However, scientists are finding that theres more to this spectacular demonstration than meets the eye. https://www.scientificamerican.com/article/bring-science-home-coke-mentos/. 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. The child who died from combining Mentos and Coca-Cola story is an updating of an older legend that began in 1979. Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. Learn all about the secrets that make seeds grow and the conservation power of Water Jelly Crystals. 1 and 3. The Hypothesis. This increase means that the molar concentration of the gas in the solution must drop for the same value of the partial pressure, which implies that gases become less soluble in liquids as the temperature increases. It truly is the perfect chemistry kit for kids who want to explore. 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. We also examined the reaction between Mint Mentos and Diet Coke, Caffeine Free Diet Coke, Coca-Cola Classic, Caffeine Free Coca-Cola Classic, seltzer water, seltzer water with potassium benzoate added, seltzer water with aspartame added, tonic water, and diet tonic water. 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! 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. Be ready. Many consider Diet Coke to be the optimal option, and it's been studied and confirmed as having the strongest effect. Lee Marek and "Marek's Kid Scientists" were the first to publicly demonstrate the experiment on the Late Show with David Letterman in 1999. The moment the pin was pulled, a slider ring resting above the pin fell into place and covered the holes where the trigger pin once was. The key is to keep every launch fair and to make sure the only variable is the temperature of the soda. The scale bar for (a) is 100m and for (b) is 20m. First, we learned that the massive buildup of pressure occurs when carbonation causes bubbles to accumulate on the surface of the Mentos. Warning - you are about to disable cookies. . Carbon dioxide creates the bubbles in soda. 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. Set up 16oz coke bottle and attach geyser tube and launch. What effect does temperature have on the height of the geyser? The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released. 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. WebPut 5 room temp Mint Mentos in a geyser tube. What is the conclusion of Mentos and Coke experiment? 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. Each bottle will receive a different number of Mentos. For each of the samples a (10m)2 image was acquired, and the root-mean-square (rms) roughness in the image was reported. Test your dog's preferred diet in this fun experiment. Mentos and Diet Coke Experiment. Adding salt to soda also causes it to foam because thousands of little bubbles form on the surface of each grain of salt. [2], The nucleation reaction can start with any heterogeneous surface, such as rock salt, but Mentos have been found to work better than most. If the partial pressure of the gas above the liquid is higher, then more gas can be dissolved in the liquid. Assuming that youre using the paper tube method, youll want to load the seven Mentos into the tube, cover the bottom of the tube with your finger and position the tube directly over the mouth of the bottle. And there is a way to make it really go boom if you have a few pennies and a bit of time on your hands. All of the samples were at room temperature unless otherwise indicated. This chemistry science kit includes activities for solo and group experiments, making it a fantastic addition to your classroom or for fun at home. The video was titled Extreme Diet Coke & Mentos Experiments. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. 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. Watch as they vanish right before your eyes in water as they grow. The amount 54020g of mass was lost from the diet tonic water, 43020g of mass was lost from the tonic water, and 945g of mass from the seltzer water. The colder the liquid, themoregas can be dissolved in that liquid. The potassium benzoate and the aspartame are active ingredients in the Mint MentosDiet Coke reaction, but the aspartame likely contributes more to the reaction. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? 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. 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. Repeat the process, varying the opening that the soda erupts from. 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. Before you get started, youll need to find a location suitable for the experiment. This, in turn, allows the soda to form smaller bubbles that can retain its structure for longer due to the reduced surface area of the bubble. Dropping something into the Diet Coke speeds up this process by both breaking the surface tension of the liquid and also allowing bubbles to form on the surface area of the Mentos. How many protons and electrons are present in Ba2+? 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]. The average times were 0.7s for the Mentos, 1.0s for the rock salt and the Lifesavers, and 1.5s for the sand. Stack the Mentos candies (approx. Why does Diet Coke and Mentos explode more than regular Coke? All Rights Reserved. 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. WebThe Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. 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. The Fruit Mentos and the Mint Mentos reaction lost roughly the same amount of mass, but the Fruit Mentos reaction took place over a shorter time and therefore the spray traveled much farther than the Mint Mentos reactions. And you may not have a friend for a day or two until they forgive you. 8:30 am 5:00 pm (MST), Steve Spangler Science Please follow us on Medium and on Instagram, thanks! The other bottles were heated in a water bath on a hot plate for approximately 1020min. The activation energy for the release of carbon dioxide from Diet Coke by the addition of Mentos is 25 kJ mol1.

Once youve got your location squared away and your supplies gathered, carefully open the bottle of diet soda. To directly compare the aspartame with the potassium benzoate we dropped 16g of Mint Mentos into a 1l bottle of seltzer water with 7.5g of added potassium benzoate and the same amount to a 1l bottle of seltzer water with 7.5g of added aspartame. WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. All of our results seem to contradict the aforementioned Mythbusters experiment. The average distance traveled by the sodas spray during the explosion is given in Table II. Why does the reaction happen? To switch between accounts click on the account below. Drop the Mentos into the diet soda. Its time to put your favorite soda to the test in this fun experiment. Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle. Thats why its called a Baby Soda Bottle! 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. 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. (2019, December 18). Henrys law applies to gases dissolved in liquids, such as the carbon dioxide gas dissolved in Diet Coke and other sodas. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. 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. 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. As luck would have it, the solution to the problem was within arms reach of the Wintergreen LifeSavers in the candy aisle: Mentos chewy mint candies! What is the fastest way to level up pickpocketing in Skyrim? There are two reasons Mentos work so well for this experiment. For the temperature dependent trials one of the Diet Coke 2l bottles was refrigerated for several hours prior to the experiment. We used the measured contact angle to calculate the minimum work required to form a critical bubble5 by the relation: where LV is the liquid-vapor surface tension, PP is the pressure difference across the interface, is the contact angle, and the function f() is given by. We examined the reaction between Diet Coke and samples of Mint Mentos, Fruit Mentos, a mixture of Dawn Dishwashing detergent and water, playground sand, table salt, rock salt, Wint-o-Green Lifesavers, a mixture of baking soda and water, liquid gum arabic, and molecular sieve beads (typically found in sorption pumps). Also, the coating dissolves very rapidly in water, and so is not effective at preventing the growth of carbon dioxide bubbles.
