Diet soda uses artificial sweeteners instead of sugar, and consequently, it’s not sticky. To enforce the fairness factor, you must stick with one brand of soda for the entire test. What is the effect of temperature on the height of the geyser? Great question! Leave the snow out to dry and reuse it again and again! 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, and the Mentos dropped into the soda. Made with superabsorbent polymers designed to grow almost four times their original size. Make sure to check out our collection of simple science experiments for kids.. Our science experiments are designed with you, the parent or teacher, in mind! However, by the end of the 1990s, the manufacturer of Wintergreen LifeSavers increased the size of the mints (no one was ever certain why this happened), making the diameter of the candy too large to fit into the mouth of the soda bottle. 15. Include a research question; the independent, dependent and controlled variables; and a simple procedure. You could use a beaker or a graduated cylinder to measure the remaining liquid in milliliters. Does warm soda shoot up higher than cold soda? Explore: (Of course a wax coating would render just about anything inert in this experiment; wax-coated sodium would have given the same reaction.) KUSA-TV News posted that original video on their website along with my blog post titled, “News Anchor Gets Soaked!” Within a few weeks, links to the video and my blog entry numbered in the thousands. I first saw the Diet Coke and Mentos experiment during a science fair at an elementary school in 2005, and I was instantly hooked! Let’s use Diet Coke in this example. 3-2-1 drop the Mentos!

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. Learn about hydrogels and how they’re used to help the environment. The real learning takes place when you start to change one variable at a time to see how it affects the performance of the geyser. Create super absorbent giant growing jelly marbles that absorb 150 times their weight in water. Design and write an experiment that uses the knowledge gained in this activity to investigate this reaction. run away! We chose to use a smaller bottle for this experiment, while we figured out the best Mentos to Soda Ratio. The Diet Coke and Mentos reaction is a fun demonstration in chemistry and physics classes of many important concepts in thermodynamics, fluid … We use the information to track views of the site, where you go and to know if you are a regular visitor or brand new as well as provide a personalised experience where possible. Because Mentos mints didn’t have holes in the middle like LifeSavers, getting them into the bottle was tricky. You’ll want to purchase three bottles of Diet Coke and two rolls of Mentos. Design and write an, experiment that uses the knowledge gained in this activity to investigate, this reaction. Is there another way for the CO2 to escape? The winning Geyser Tube design was a clear plastic tube with a special fitting that twisted onto any soda bottle. Features 13 spooky experiments that fizz, pop, scream, smoke, bubble and erupt for 24 guests, Call: 303-798-2778 You’ll need a thermometer to record the temperature of the soda just before you launch it. . Both worked. There is. This final step is very important . I also posted the video on a new online video sharing site called YouTube (YouTube was only 7 months old at the time), and as they say, the rest is history. It just won’t be nearly as awesome.) Unfortunately, the method for dropping the Mentos was never consistent. The basic science of the Coke and Mentos reaction is fairly straightforward. In the science world, this physical reaction is called “Nucleation” (Nuc-le-ate-ion). The Mentos Geyser became one of my featured demonstrations both on television and during my live stage presentations. In the video below you can see this experiment play out in slow motion. In fact, it’s not really a reaction at all – or at least it’s a physical reaction rather than a chemical one. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve. Special fluorescent ingredient added to create an eerie glow in the dark. Soda And Mentos Experiment Research Paper. This one was really fun! Investigate the reactivity of metals. Bubbles are formed and it pushes the liquid up and out of the bottle causing an eruption. For added scientific fun, experiment and investigate changing different variables. This activity is probably best done outside in the middle of an abandoned field or on a huge lawn. The subject of the experiment is the well-known Diet Coke and Mentos reaction. Assuming that you’re using the paper tube method, you’ll 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. Simply dropping Mentos into a bottle of soda to make a geyser isn’t really science—it’s just a fun trick to do in the backyard. Design and write an experiment that uses the knowledge gained in this activity to investigate this reaction. Put mentos in the the Diet Coke 2. The Big Blast But there was one added bonus . 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. The kit comes with the essential materials you’ll need to conduct 5 experiments, take-it-further activities and challenges for 1 – 4 children per kit. Half-fill separate test-tubes with copper(II) sulfate, magnesium sulfate and zinc sulfate solutions. B) Mint Mentos D) Lemon Heads. . The speed at which the Mentos falls through the Diet Coke can affect how large the eruption is. ... but the diet soda produced a bigger reaction. Independent variable mentos Dependent variable Diet Coke Controlled variables Numbers of mentos Procedure 1. 15. Position the bottle on the ground so that it will not tip over. Mentos in Coke experiment. The warmer the liquid, the less gas can be dissolved in that liquid. 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. The original reason I invented the Geyser Tube toy was to find a way to standardize the actual drop of the Mentos. Back up because it’s going to … Have a good day :) Hypothesis: I predict if you drop a mentos in the diet coke, bubbles will form and push the liquid up and out of the bottle because I believe that mentos and diet coke will cause a reaction. If you’re not using the Geyser Tube, make sure to come up with your own method for dropping the Mentos into the soda the same way each time. Learn How to Design a Project and Collect Data. Add a piece of iron to each test-tube. so I’m going to go with Mentos. Drop two Mentos into the second bottle, and so on until you’ve completed all ten bottles. Within the next 12 months, over 800 Mentos Geyser-related videos were posted on YouTube, making the demo one of the most popular pop-culture science experiments in recent history. Drop one Mentos into the first bottle and record the height by counting the wet bricks (or set up your own scale behind each soda bottle). Make sure when you do scientific activities of any kind to go ask questions, go through the scientific method and have them form a hypothesis and discuss if they were correct at the end. As the molecules move faster, they diffuse out of the liquid, leaving less gas dissolved in that liquid. . It’s been called the “vinegar and baking soda” reaction for a new generation. 1. This is a great topic for a science project—you’ll need lots of soda and Mentos, and a few friends to help record all of the data. The perfect slime for Halloween, but is sure to amaze and excite any time of year. 2 liters!) Watch it grow and learn about super-thirsty polymers, Voted BEST HALLOWEEN SCIENCE KIT by Parents Magazine. the restricted hole at the top of the plastic tube helped to build up more pressure in the bottle and launched the soda 30 feet into the air. Unfortunately, Kim got so caught up in the fun that she forgot to do both . 15. We also tried it with coloured mentos and mint Mentos. It’s also important that all of the test bottles are stored in the same place so that the liquid in each bottle is the same temperature. To add insult to injury, she did it two more times, each time getting covered in more soda, until her once pink dress was more Coke-colored than pink. Tips: More Mentos® are better than fewer. The first experiment the boys wanted to was to test the amount of Mentos we needed. ... Research Question What does the Diet Coke have that makes the Mentos react? 1 A more detailed description of the experimental results has been published elsewhere. If you want to examine the volume of the geyser instead of the height, make note of the volume of a full bottle of soda before you drop the Mentos into it. Include a research question; the independent, dependent and controlled variables; and a simple procedure. How to Turn Water Into Liquid Gold. Mentos® and Soda Task Annotation – Revised Summer 2017 5 . 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. ), Launching Potatoes - How to Make a Potato Gun, A roll or box of Mentos chewy mints (stick with the standard mint flavor for now), 2-liter bottle of diet soda (either diet or regular soda will work for this experiment, but diet soda is not sticky when you’re cleaning it up, and it will usually create a bigger blast), Make sure the soda is at least 85 degree Fahrenheit, Drop seven Mentos into the soda all at the same time. The colder the liquid, the more gas can be dissolved in that liquid. An index card (picture below) The Mentos And Coke Volcano Experiment The key is to keep every launch fair and to make sure the only variable is the temperature of the soda. Super-absorbent giant growing polymer beads. 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. Everyone found their own method of quickly dropping the Mentos into the soda. It’s important to use the same number of Mentos for each test and to drop them the same way. Drop Mentos into a bottle of soda and run away from the 20 foot geyser. We dropped two Mentos into a bottle of normal Cola and Diet Cola. If you’re doing a science fair project, your initial question might be, “What is the effect of the brand of soda on the height of the geyser?” We tried it with cola and lemonade. The reaction has been performed numerous times on television and the Internet, but has not been systematically studied. . Do a side-by-side test with the Mentos® fountain you designed (the baseline design on the worksheet) and the fountain design based on the collaborative class research. You can also place the bottle of unopened soda in a bucket of warm water. This low temperature allows the maximum amount of CO2 to dissolve in the soda, keeping the carbonation levels as high as possible. For example, adding salt to soda causes it to foam up because thousands of little bubbles form on the surface of each grain of salt. If the student experiments went well, expect their fountain to be higher. 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 tiny pits and imperfections on the inside surface of the bottle called nucleation sites). Again, both worked. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. This is because as the liquid is heated, the gas within that liquid is also heated, causing the gas molecules to move faster and faster. I originally found this experiment on Kitchen Pantry Scientist as well as Steve Spangler Science!. Coke and Mentos Experiment. Of course, this could go on forever, but you’ll start to see a trend in your data that shows the maximum height of the geyser for a certain number of Mentos. A) Skittles Materials: * 1 Roll of mentos mint candies * Paper and tape to make a paper tube * Index card * 2 liters of bottled diet or regular soda Procedure: 1. Shake it 3. In other words, the liquid sprays everywhere. Will frozen mentos or room ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 40924e-YjU5Z Try this. Why? Design and write an experiment that uses the knowledge gained in this activity to investigate this reaction. I loved all the experiments and i would like to do all of them. The gas released by the Mentos literally pushes all of the liquid up and out of the bottle in an incredible soda blast. Making Perfume Safely. There are two safe ways to warm the other bottle of soda. The secret is to turn your attention away from the spraying soda and concentrate on setting up an experiment where you isolate a single variable and observe the results. . Many experiments designed to investigate the reaction of Mentos® with Diet Coke® have been documented on YouTube. These are CO2 bubbles leaving the soda and attaching themselves to the object. Why are Mentos so Special? Using any more than seven Mentos is just a waste, according to these soda-soaked science enthusiasts. A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. 14. How many Mentos Do You Need? Room temperature soda is better than cold. A friend or parent with a video camera is a great way to watch and document the results of your experiment, but you’ll also need some specific measurements or data. Place one bottle of Diet Coke in the refrigerator and let it sit overnight. See more ideas about mentos and coke, coke, diet coke. This science demonstration was popular among chemistry teachers back in the 1980s using a roll of Wintergreen LifeSavers and a pipe cleaner. So, I solicited help from our creative team at Steve Spangler Science to come up with a Geyser Tube— a better, more consistent way to drop the Mentos into the bottle. Absorb 150 times their weight in water! The thing that makes soda bubbly is invisible carbon dioxide (CO2), which is pumped into bottles at the bottling factory using lots of pressure. It's good practice for more advanced science and it gets the mind working. Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. The simplest method is to let the unopened bottle sit in the sun for several hours. this anticipation is killing me. But don’t forget to look back at the amazing eruption of soda. Extension Questions Many experiments designed to investigate the reaction of Mentos ® with Diet Coke ® have been documented on YouTube. Line up a row of ten 2-liter bottles against a brick wall (see “Measuring the Height of the Geyser”). Include a research question; the independent, dependent. The reason why Mentos work so well is twofold—tiny pits on the surface of the mint, and the weight of the Mentos itself. Abstract: Placing a mentos candy in a bottle of diet coke will cause bubbles to react. It needs to be wide enough to use as loader for the Mentos. The only variable you’ll change in this test is the brand of soda while everything else remains the same (the number of Mentos and the amount of soda). For added scientific fun, experiment and investigate changing different variables. . Mentos Geyser Experiment Science Mentos Geyser October 2009 Question/Purpose I want to create a chemical reaction using soda and mentos. No matter which brand of soda you tested, the warm bottle probably produced the highest-shooting geyser. In colder liquids the gas molecules move very slowly, causing them to diffuse out of the solution much more slowly. Many scientists, including Lee Marek, claim that the Mentos phenomenon is a physical reaction, not a chemical one. and got soaked in Diet Coke on live television. . To perform this experiment, Mentos candies are dropped into a bottle of carbonated beverage; Diet Coke tends to be the beverage of choice. But the bottom line was that we needed to find a way to standardize the drop of the Mentos. Experiment - Mentos and soda foldable for each student ; Have the Experiment steps for Mentos and soda experiment printed, cut out, and placed in baggies for those students needing assistance with copying. Many experiments designed to investigate the reaction of Mentos@ with Diet Coke@ have been documented on You Tube.

You might be asking yourself, “Can I use the Mentos Geyser for my science fair project?” The answer is YES, but you’ll need to learn how to turn a cool science activity into a real science experiment. Fruit flavored mentos we designed in the 1940s, before carbonation was discovered (in Bolivia, of all places!). And, since bottling - to preserve the fizz - wasn't invented until 1977 The first bottling plant was in Denmark, not sure, though) the Mento-Coke thing was a miracle long in the making. Never use a stove or microwave to heat a bottle of soda. Try placing the soda bottle next to the wall of a brick building (after getting permission from the building’s owner). To find out more, Coffey and a team of students tested the reactions between Diet Coke and fruit Mentos, mint Mentos, and various ingredients … In an experiment popularized online, what candy creates an explosive geyser when dropped into a 2-liter Diet Coke bottle? Why do you think so? Measuring the Volume of the Geyser Experimental Question: What will happen if you dropped a mentos candy in a bottle of diet coke? Toll Free: 800-223-9080 This was my favorite of our Fascinating Science for Kids experiments…although it only lasted about 20 seconds. Can you believe there's more to say on the Diet Coke and Mentos story? As they say, the simplest design usually turns out to be the best and most elegant solution to the problem. 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. What is different about the original flavor mints? This leads to the classic Mentos and Diet Coke eruption. To perform this experiment, Mentos candies are dropped into a bottle of carbonated beverage; Diet Coke tends to be the beverage of choice. Better yet, if we could trigger the drop of the Mentos from a distance, we wouldn’t get as wet. We’ll send you a free experiment every week, plus new products and offers. Design and write an experiment that uses the knowledge gained in this activity to investigate this reaction. 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. How Many Mentos Work Best? Measuring the Height of the Geyser There is a lot of science to be discovered in a bag of candy that goes way beyond tasting it and enjoying it. Instead it is a physical reaction. The goal is to drop all seven Mentos into the bottle of soda at the same time (which is trickier than you might think). Color your own marbles and learn about secondary colors! You’re going to set up three tests—warm soda, room temperature soda, and cold soda. Remember that 1 liter is equivalent to 1000 mL. . Drop an object like a raisin or a piece of uncooked pasta into a glass of soda and notice how bubbles immediately form on the surface of the object. Discover how to mix primary colors and create secondary colors. After completing all of these tests, you’ve become somewhat of a Mentos Geyser expert who has the research to support the answer to the question, “How can you make the highest-shooting Mentos geyser?” Each test isolated an independent variable, and combining all of the information you discovered into one launch is a great way to wrap up your science fair project. 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. COKE AND MENTOS. Record the temperature. Each bottle will receive a different number of Mentos. More gas tends to stay in solution when the liquid is cold. Trying to fit 2 packs of Mentos into a bottle was near impossible. . Other methods include using a large plastic test tube to hold the Mentos or using my Geyser Tube toy invention, which was created to solve this very problem. . Warm soda tends to fizz much more than cold soda. You guessed it . Dropping Mentos into a bottle of diet soda causes a physical reaction: as they fall through the soda, the Mentos candies break the bonds between the carbon dioxide and water (the combination that makes soda fizzy), releasing the carbon dioxide gas up and out of the bottle. This is why at the bottling plant CO2 is pumped into the cans or bottles when the fluid is just above freezing—around 35 degrees Fahrenheit. Just think . … . 14. A tube the width of the Mentos. Make comparisons, create a chart with your data, and draw some conclusions. I first saw the Diet Coke and Mentos experiment during a science fair at an elementary school in 2005, and I was instantly hooked! You might have used the test tube method while someone else made a tube out of notebook paper. What is the Mentos and Soda Experiment? As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles. Fueled by hundreds of blogs and popular online sharing sites like youtube, this once obscure reaction became an Internet sensation, and the enthusiasm for dropping Mentos into soda continues to grow. Include a research question; the independent, dependent and controlled variables; and a simple procedure. Projects & Experiments. Projects & Experiments. We even played with ways of using the Geyser Tube to trigger multiple soda geysers in a method similar to a Rube Goldberg machine. . 7901 Southpark Plaza, Suite 106Littleton, CO 80120, Steve Spangler’s Geyser Tube toy (optional . Enough waiting . Mentos and Coke Experiment; Separate a Mixture ; One note before I move on to the activities. and controlled variables; and a simple procedure. Their first video, The Extreme Diet Coke & Mentos Experiments, took the idea of dropping Mentos into soda and turned it into one of the best known viral videos of all time. The answer lies in the solubility of gases in liquids. Repeat the same procedure for the bottle of soda at room temperature and for the bottle of warm soda. Design and write an experiment that uses the knowledge gained in this activity to investigate this reaction. Does the number of Mentos placed in the Diet Coke affect the height of. The trigger pin at the bottom of the tube prevented the Mentos from falling into the bottle until you pulled the string attached to the pin. Later on in the experiment, you’ll be invited to compare the geyser power of diet versus regular soda, but for now we’ll start with a 2-liter bottle of diet soda. Extensions could include actually conducting the designed investigation within the … To get the best results in a science experiment you need to standardize the test conditions as much as possible. Each Mentos mint has thousands of tiny pits all over the surface. However, I must admit that even with the Baby Soda Bottle method, the results were not very consistent and it was challenging to get away from the bottle before it exploded. . Let’s start with seven Mentos for our first attempt. It’s time to return to your launching site. This has to be the number one question everyone asks about this experiment. The science experiments my children talk about for months afterwards are generally the messy ones, like our splatter patterns, glow in the dark oobleck, baking soda experiments and the well known coke and mento experiment.. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos. . but highly recommended! Once you get past the initial gee-whiz factor, there’s some amazing science behind a carbonated beverage and a chewy mint. Have the Procedure for Mentos and soda experiment copied and cut out for all students not needing the accommodation for writing less. This bubbling process is called nucleation, and the places where the bubbles form, whether on the sides of the can, on an object, or around a tiny grain of salt, are the nucleation sites. Include a research question; the independent, dependent and controlled variables; and a simple procedure. your results could help determine the next Mentos Geyser craze! Watch a secret message disappear and reappear right before your eyes. Many experiments designed to investigate the reaction of Mentos® with Diet Coke® have been documented on YouTube. Make a Super Cool Spinning Steel Wool Sparkler. As luck would have it, the solution to the problem was within arm’s reach of the Wintergreen LifeSavers in the candy aisle—it was Mentos chewy mints. The kit comes with the essential materials you’ll need to conduct 3 experiments and challenges for 1 – 4 children per kit. You can use candy to discover the ways molecules interact and behave. My cohost for the KUSA-TV science segment was the lovely Kim Christiansen. Mentos have a surface texture that increases the speed of the reaction. process for investigations which include testing appropriate variables. Include a research question; the independent, dependent and controlled variables; and a simple procedure. Extension Questions - Fundamentals of Experimental Design.docx - Extension Questions Many experiments designed to investigate the reaction of Mentos, 1 out of 1 people found this document helpful, Many experiments designed to investigate the reaction of Mentos, have been documented on YouTube. We love fizzing experiments and have been exploring chemistry for kindergarten, preschool, and early elementary for almost 8 years. The biggest challenge in the Mentos Geyser experiment is finding a consistent way to drop the Mentos into the soda every time. While I had performed variations of the Mentos Geyser experiment on television many times from 2001 to 2004, my performance of the demo in September of 2005 in the backyard of NBC affiliate KUSA-TV in Denver proved to be the tipping point as the demo went from relative obscurity to Internet sensation. The brand of soda is the only thing that changes (the variable). Some people fashioned a tube out of paper while others used a piece of plastic tubing to load the Mentos. This experiment is about the physical reaction between the fizzy carbonation that is pumped into every delicious soda, and the layers of sugar coating that is found on every Mentos candy. Monday – Friday When you pull your finger out of the way, all seven Mentos should fall into the bottle at the same time. These tiny pits create a larger surface area and essentially provide many more "nucleation sites." When you open the container, the bubbles quickly rise to the top pushing the liquid out of the way. Again, make sure all of the soda is at the same temperature because temperature plays an important role in the reaction. In the video below you can see this experiment play out in slow motion. :V on March 01, 2017: Thank you for the ideas! . Open the bottle and dip the thermometer down into the soda. 8:30 am – 5:00 pm (MST), Denver Office https://www.science-sparks.com/infamous-coca-cola-mento-trick The Geyser Tube removes the inconsistency because it makes the drop the same every time, letting you focus on the tr… Again, the choice of diet over regular soda is purely a preference based on the fact that erupting regular soda becomes a sticky mess to clean up because it contains sugar. (Examples include but are not limited to: modifying the number of Mentos® dropped, changing the soda flavor, brand, or temperature) ESTIMATED TIME 15-30 Minutes @home In collaboration with: Funded by: science-u.org. Projects & Experiments. Soda pop is made of sugar or artificial sweetener, flavoring, water, and preservatives. But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! Projects & Experiments. 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. You know the Mentos Geyser is a popular experiment when a producer from ABC’s Who Wants to Be a Millionaire calls for help writing a question.
