CONCLUSION: My hypothesis that the number of Mentos candy would affect the height of the explosion was correct. What you need. (5) The pressurized carbon dioxide in the Coke escapes when opening the bottle and creating fizz, so the Mentos breaks the surface tension of the coke which speeds up the fizzing. What this means, is that it usually does not involve problem solving or predictions. Did you know the classic “mentos & soda” experiment is actually a demonstration. You might think that there is some ingredient in a Mentos candy that is causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. Instead, it simply demonstrates the reasoning behind the explosion of soda. (4) More bubbles are made as the Mentos falls down the bottle of Coke. Put the open end of your tube of Mentos on the card and place it directly over the opening of the soda bottle. In fact, it was so much fun that I wrote up our experiment, created observation and tracking sheets, and have uploaded them all for you to use…for free! In the Diet Coke bottle the Mentos candy provides a rough surface that allows the bonds between the carbon dioxide gas and water to break more easily, helping to create carbon dioxide bubbles. Mentos in Coke experiment. Introduction. 1. Have you heard about the "Mentos in Coke" phenomenon? if its in a can of course it wont go 5 feet it should be in a 1.5 liter bottle of coke[i dont know if diet works] with 10 or more mentos then those mentos should go down at the same time or right away not one by one! Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom. Place it on a flat area outside where it is OK to get wet with soda. ! COKE AND MENTOS. Try it out for yourself and teach your kids some simple science facts. The Diet Coke and Mentos experiment (shown in action in Figure 1 below) is all over the Internet, but how does it work? Slowly and carefully open a new bottle of Diet Coke. But this is not a chemical reaction at all! 3. The Diet Coke and Mentos experiment was a blast (literally!) Mentos and Diet Coke Experiment. I assumed that the more candy pieces used would produce a higher explosion and this was true when comparing the trials using one and three pieces of … and we learned a lot about nucleation. Read the experiment below or scroll allllll the way to the bottom to get the printable version. We love fizzing experiments and have been exploring chemistry for kindergarten, preschool, and early elementary for almost 8 years. Our Mentos and soda experiment is a fun example of a physical reaction. 2. It's a simple science experiment that your kids will go nuts for. Share this science project . For now, it’s clear that there’s still plenty to learn about the best way to make the biggest Coke and Mentos fountain! Steph Wu | July 03, 2017. Carbon dioxide creates the bubbles in soda. All you do is drop a tube of Mentos candies into a bottle of soda. 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! 3 Variations of Mentos and Soda Experiment Setting up the Experiment. The carbon dioxide in the soda comes out of solution very suddenly, shooting up into the sky and drenching anyone within range with soda. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke. The Mentos Trick .
