Observe and explain the Mentos and Diet Coke experiment. This conclusion is also supported by the ingredients in the Mentos, none of which are basic: sugar, glucose syrup, hydrogenated coconut oil, gelatin, dextrin, natural flavor, corn starch, and gum arabic. Average horizontal distance traveled by the spray during the reaction. The AFM rms roughness measurements are given in Table V. The SEM images of some of the samples are shown in Figs. When the candy hits the bottom of the bottle, the gas is released and pushes the soda from the bottle up in the air in an amazing eruption! Pull the index card away swiftly, dropping the candies into the soda. As mentioned earlier in the article, using either diet coke or regular coke alongside mentos can produce a spewing geyser of carbonation bubbles. Write down what happened when you dropped the Mentos in the coke. 1 So the relatively small amount of caffeine in a 2 l bottle of Coke doesnt significantly affect the reaction. Youve probably heard that you shouldnt eat Mentos while you drink Coke, but why is that? 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. 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. The temperature was 52 F. In this experiment, mentos caused a eruption in a 2-liter bottle of Diet Mountain Dew erupted, thus we concluded that diet Mountain Dew This is an urban myth. The popular Diet Coke and Mentos reaction occurs when new Mentos are dropped into a fresh bottle of Diet Coke and results in a jet of Diet Coke spray shooting out of the mouth of the bottle. Conclusion. 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. The rms roughness of a 100m2 image acquired in the AFM. [1], Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. Introduce the concepts of chemical bonding, cross-linking of molecules. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual. The Diet 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. What happens when you put Mentos in soda? The color combined with the small size of the salt grains made it too difficult to see, and therefore difficult to determine the time of fall for the table salt. Mentos Experiment Now remove the index card and let candies fall in and step away from the Mentos and coke volcano. Its also a lot less work than your classic paper mache volcano. The mass 41020g was lost from the aspartameseltzer water mixture and 36020g of mass was lost from the potassium benzoateseltzer water mixture. Of these three highly eruptive reactions, the Wint-o-Green reaction lasted the longest and lost a comparable amount of mass to the others, but traveled a much shorter distance than the Fruit and Mint Mentos reactions.
