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. Henrys law applies to gases dissolved in liquids, such as the carbon dioxide gas dissolved in Diet Coke and other sodas. What is the fastest way to level up pickpocketing in Skyrim? The activation energy for the release of carbon dioxide from Diet Coke by the addition of Mentos is 25 kJ mol1. Why does Diet Coke and Mentos explode more than regular Coke? 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. Later on in the experiment, youll be invited to compare the geyser power of diet versus regular soda, but for now well start with a 2-liter bottle of diet soda. There is not always a direct correlation between the mass lost and the distance traveled for the reactions. What is the dependent variable in Coke and Mentos experiment? [10] When the pressure is released from a soda bottle upon opening it, dissolved carbon dioxide can escape into any tiny bubble located within the beverage. 8:30 am 5:00 pm (MST), Steve Spangler Science Gruber, B. ", "Science of Mentos-Diet Coke explosions explained", "Bubble nucleation from gas cavities a review", "Ethanol as a Probe for the Mechanism of Bubble Nucleation in the Diet Coke and Mentos Experiment", "Does the Mentos and Soda Trick Work With Regular Coke? In this experiment, you will evaluate whether or not a diet that is supplemented with "brain-enhancing" foods can help improve memory. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? 1(d) is a magnified view of the top of a salt grain. Average mass lost during the reaction. [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. The only variable youll change in this test is the brand of soda; everything else will remain the same. Enough mass was deposited by the Hawaiian hot spot to form the islands, but the eruptions were comparatively gentle.) View the Mentos Geyser Experiment here! The dependent variable was the height of the rise of Coca-Cola. 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. The scale bars in each image represent the lengths (a) 200m, (b) 100m, (c) 20m, and (d) 20m. Carbonated sodas contain elevated levels of carbon dioxide under pressure. This will help you make an informed guess as to what will happen. The child who died from combining Mentos and Coca-Cola story is an updating of an older legend that began in 1979. 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.). What is the independent variable in the Mentos experiment? http://www.eepybird.com/featured-video/coke-and-mentos-featured-video/science-of-coke-mentos/. He will be performing the crushed vs whole candy in a diet coke. It truly is the perfect chemistry kit for kids who want to explore. It comes with six fun experiments, a test tube rack, fizzing tablet and vegetable oil chemicals to play around with. https://www.scientificamerican.com/article/bring-science-home-coke-mentos/. Its time to put your favorite soda to the test in this fun experiment. We knew the Mentos Geyser Experiment was a popular experiment when a producer from ABCs Who Wants to Be a Millionaire called for help when writing a question. The contestant ended up doing really well, going all the way to the $250,000 question; however, he walked away with $125,000. The speed with which the sample falls through the liquid is also a major factor. Cover the opening of the test tube with an index card or similar slim, small paper. It proved challenging to get away from that bottle before it exploded. WebThis is a fun and exciting experiment designed for 3rd-6th graders. So what really causes this phenomenon? Le Chateliers principle states that, If, to a system at equilibrium, a stress be applied, the system will react so as to relieve the stress.6 In our experiment the stress we are applying increases the temperature of the Diet Coke. Only one trial was performed for each temperature. Great integration of science and literature. A one gallon bucket containing test tubes of over 10 Spangler Labs originals, Features favorites like Insta-Snow, Energy Beads, Jelly Marbles, & Magic Sand. Figure 1(c) is a magnified view of the edges of a salt grain, and Fig. 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 demonstrations on this reaction have been implemented. It has also been shown that a wide variety of beverage additives such as sugars, citric acid, and natural flavors can also enhance fountain heights. If you want a more specific measurement, use chalk to mark off 1-foot increments before you drop the Mentos into the bottle of soda. WebCONCLUSIONS: ( Do you accept or reject your hypothesis, and why or why not) You and your partner will share your experiment with the class. We have shown here via contact angle measurements that these ingredients reduce the work required for bubble formation, allowing carbon dioxide to rapidly escape from the soda. [2], The nucleation reaction can start with any heterogeneous surface, such as rock salt, but Mentos have been found to work better than most. After this, two interested scientists from the entertainment company EepyBird, Fritz Grobe and Stephen Voltz decided to post a Youtube video demonstrating this experiment and it went viral, gaining 120 million views. Pre-existing bubbles provide a way for the reaction to occur without requiring bubbles to form within the liquid itself (homogeneous nucleation). American Journal of Physics 1 June 2008; 76 (6): 551557. June 15, 2008 -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Mentos and Diet Coke Experiment. Youll need a thermometer to record the temperature of the soda just before you launch it so that your data are accurate. 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. Hall, Magdalena Jaramillo, Cully Little, and Zach Russell, and my graduate research assistant, Jon Jones. I must admit, however, that even with the Baby Soda Bottle method, the results were not very consistent. For each of the samples a (10m)2 image was acquired, and the root-mean-square (rms) roughness in the image was reported. students used this simple device to monitor the kinetics of foam production in the Diet Coke and Mentos experiment and to draw conclusions about the system. The enthusiasm for dropping mints into soda bottles continues to grow today. Dont forget to look back at the amazing eruption of soda. Fortunately, the maker of Mentos (Perfetti Van Melle) also liked our Geyser Tube design. 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. WebThis product walks you through the scientific method using two different experiments: -- How different types of soda react when Mentos is added to them- How Coke reacts to Mentos vs. how it reacts to baking sodaStudents will make an observation, ask a question, create a hypothesis, conduct an experiment, record results, and write a conclusion. 4, and some of the AFM images are shown in Figs. To the naked eye, Fruit Mentos are shinier than Mint Mentos, and therefore should be smoother. It should not introduce any new information, but rather summarize the key points made in the discussion section. This increase moves the system away from the equilibrium condition for that molar concentration of the gas. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. While the reaction remains fairly the same regardless of what carbonated beverage you use for this experiment, diet sodas are usually more carbonated and fizzy compared to regular sodas. EepyBird.com Entertainment for the Curious Mind. 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. WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. Make comparisons, create a chart with your data and draw some conclusions. Hall, Jonathan Hearing, Leander Hutton, Kelly Izlar, Cully Little, James Lugenbell, Michael Mace, Bonnie Myers, Carla Penders, Zach Russell, Shane Shields, Adrian Steffen, Tony Sturtzel, and Zach Yokley. If you decide to do this experiment against a wall, be sure to thank the buildings owner and to hose off the wall of the building when you are finished. 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 warmer the liquid, thelessgas can be dissolved in that liquid. Use your data from the previous test to determine the standard number of Mentos candies to use for this test. The most striking example is the molecular sieve beads, which lost a significant amount of mass but only traveled 2.5ft. [1], Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. However, is one better for use during an experiment? 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. Mentos candies contain millions of cavities, roughly 1-3 m in size,[25][10] that remain unwetted when added to a soda. 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.
