American Journal of Physics 1 June 2008; 76 (6): 551557. Next, some thought that the pH of the liquid was responsible for the vigorous reaction. Surface roughness has often been cited as the most important cause of the Diet CokeMentos reaction.13 Increased surface roughness implies a higher surface area to volume ratio, meaning that more growth sites should be present on per unit volume. First, we learned that the massive buildup of pressure occurs when carbonation causes bubbles to accumulate on the surface of the Mentos. [19], While Diet Coke and Mentos are the most common way to make a soda geyser, they are not the only options. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. The higher magnification image of the Fruit Mentos is zoomed in on one of the rougher patches. WebMentos and Diet Coke Experiment. WebConclusion Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. My son chose this experiment for his 6th grade science fair project. The most striking example is the molecular sieve beads, which lost a significant amount of mass but only traveled 2.5ft. https://www.newscientist.com/article/dn14114-science-of-mentos-diet-coke-explosions-explained/. What evidence did the team find that the reaction between the Mentos and soda was a physical change? All of the samples were at room temperature unless otherwise indicated. We put 4 mentos pieces into the bottle of diet coke. The answer is a little more complicated than you might think. He would like to know why does the shape and size of the mentos affect the outcome of the project. Drop one Mentos candy into the first bottle and record the height by counting the wet bricks or by using your own scale. Children will enjoy this hilarious story and use their hands to mix up a batch of Instant Worms. Diet Coke What happens when you mix Diet Coke and Mentos? . WebFound the trial with soda and Mentos at Steve Spangler Science, with tutorial on how at make a huge explosion. The participant got it right for $8,000, saying: I saw it on TV, and I bought Mentos and a 2-liter bottle of Diet Coke. Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. The Mythbusters correctly identified potassium benzoate and aspartame as key ingredients in the Diet CokeMentos reaction. Conclusion. Mentos Put the index card on top of the tube loader and turn the tube upside down. What is the science behind Coke and Mentos for kids? It really only takes a few minutes to setup the mentos and coke volcano experiment.

Let us know what you observed in your science experiment! Why does the reaction happen? How does the flavor of Mentos affect the explosion? Unfortunately, Kim got so caught up in the fun that she forgot to do both and got soaked in Diet Coke on live television! In a sealed bottle of soda pop, the gas above the liquid in the bottle has a high partial pressure of carbon dioxide compared to the air we breathe.
