Certain types of multivitamins and soda also produce a nice foamy reaction. Make three bar graphs of whole Mentos versus crushed Mentos: One graph of the average reaction time, one of the average geyser height, and one of the soda volume remaining. Place an unopened Diet Coke bottle at the outside area that you marked off, at least 2 m from the building and away from anything hanging above the area, such as eaves, overhangs, or wires. Anglo-Indians: Are They Fading into the History of India. It seems likely that the surface of this vitamin must have been porous and it did most likely also contain at the least the gum arabic. A Mentos candy can help with this. # Link Name="MatlSci_p023.1" Value="HtmlAnchor" HtmlText="EepyBird.com." I had not at that point thrown up in about 15 years, so this was bizarre. Science Buddies Staff. While in the beginning carbonation was added to drinks because it was thought it was beneficial to the human body, today carbonation is added for very different reasons, namely, taste and shelf life. Mentos reacts strongly to all carbonated drinks owing to some of its molecular properties. The company that prepares this extract, Stepan Company in Maywood, New Jersey, also legally makes cocaine for medicinal purposes. Science Buddies Staff. You will be testing the crushed candies in three separate trials. Steve Spangler's televised demonstration of … In fact, it was so much fun that I wrote up our experiment, created observation and tracking … Compare the results of regular and Diet Coke. Do you think that using crushed Mentos, which should have sunk slower in the soda, made a difference in the reaction? Step back without tipping the bottle over or disturbing the reaction. They watch as the soda explodes out of bottles after the Mentos are dropped in. It is important to repeat your experiment so that you are sure that your results are repeatable and reproducible. This entertaining video demonstrates how to make a bottle rocket using tape, paper napkins, Mentos, and Diet Coke or Coke Zero. Write these averages in your data table. First, the act of drinking soda releases quite a bit of the carbonation in it, limiting the possible effect. The “pop” part of the term came about in the early 19th century, with the first documented reference in 1812 in a letter written by English poet Robert Southey; in this letter he also explains the term’s origin: “Called on A. Harrison and found he was at Carlisle, but that we were expected to supper; excused ourselves on the necessity of eating at the inn; supped there upon trout and roast foul, drank some most admirable cyder, and a new manufactory of a nectar, between soda-water and ginger-beer, and called pop, because ‘pop goes the cork’ when it is drawn, and pop you would go off too, if you drank too much of it.”. Write to us at Calculate the average reaction time, geyser height, and soda volume remaining for the trials using whole Mentos and the trials using crushed Mentos. The crushed Mentos candy should sink slower than a whole Mentos candy. Determine if using crushed Mentos candies will change the height of exploding soda It seems likely that the surface of this vitamin must have been porous and it did most likely also contain at the least the gum arabic. Coke/Mentos reaction using a pH meter with a 2 point calibration. Line up where the opening of the bottle is with the opening of your cartridge. Why do you think all of this is important? Science Buddies participates in affiliate programs with Theories abound as to why … The Mentos drops to the bottom of the bottle, forming lots and lots of bubbles on its pitted surface along the way. Does Mentos gum work with Coke? Mentos® mint flavored candies (24 candies), Blue painter's tape; This can be purchased at most hardware stores or online at, Eye protection, such as goggles or glasses, Outdoor space next to an exterior wall where tape can be applied with permission. To find out the volume of Diet Coke remaining in the bottle after the eruption, pour the remaining soda into a graduated cylinder (and measure in milliliters [mL]) or into measuring cups (and measure in cups). This is another reason Mentos works so much better than other similar confectioneries. To prevent soda from possibly splashing the camera or volunteer, do not place the video camera too close to the testing spot. Now you are ready to watch your videos and analyze your data. A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. 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 did have Phosphoric Acid because it caused eruption with mentos being dropped in. On the wax paper, carefully use the knife to crush and cut four Mentos candies into many small pieces, as shown in Figure 2 below. First test the whole Mentos candies and then try the crushed Mentos candy pieces. Diet Coke and Mentos eruption A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints … Mentos® is a registered trademark of Perfetti Van Melle Corporation. If you use a smooth surfaced Mentos, you won’t get nearly the reaction. A two-liter bottle of diet soda (diet soda makes for a much better reaction, but you can use regular soda if you like. Use two Mentos and a bottle of regular Coke and record the height. 89 ($1.08/Ounce) They’ve since got around this by using cocaine-free coca leaf extract. In this materials science project, you will see if using crushed Mentos candies instead of whole Mentos candies, which should sink faster in the soda, will change the height of the eruption. You can measure the height of the geyser with a wall, a helper, and a video camera. ... + More One factor that may affect the size of the Mentos and Diet Coke eruption is how quickly the Mentos candies sink in the soda. Yet another factor that can affect the size of the Mentos / Coke geyser is the temperature of the soda itself. It also functions as a preservative, which increase the shelf life of the beverage. Repeat steps 5a to 5g two more times, for a total of three trials using four whole Mentos candies each time. Figure 1. A tube the … In the data table in your lab notebook, write down the total amount of seconds (sec) that the geyser lasted for each trial. and we learned a lot about nucleation. If you like this project, you might enjoy exploring these related careers: Try one of our science activities for quick, anytime science explorations. To create bubbles, the carbon dioxide needs to interact with itself, which means that its bonds with water in the soda must be broken. You’ll also sometimes read that the acidity of the soda is a major factor in the resulting geyser. Some other The article provides a brief of some of the causes of such a strong reaction. As I had not chewed it before swallowing, it found its way to the still somewhat carbonated liquid (although much less so having drunk it) and produced enough foam to overfill my already somewhat full stomach from dinner. But this is not a chemical reaction at all! Lee Marek and "Marek's Kid Scientists" were the first to publicly demonstrate the experiment on the Late Show with David Letterman in 1999. Science! Here is how one science fair student from Marin County, CA set up his Diet Coke and Mentos experiment. Place the tube in the top of the bottle, but don't let the Mentos … Note that while caffeine is often cited as something that will increase the explosive reaction with the soda, this is not actually the case, at least not given the relatively small amount of caffeine found in a typical 2-liter bottle of soda generally used for these sorts of Diet Coke and Mentos reactions.

Please enter a search term in the text box. On a similar note, birds will not have their stomachs blow up if you feed them dried rice or Alka-Seltzer. However, … However, Asa Candler, who eventually finagled exclusive rights to Coca-Cola, claimed that his formulation included only around 1/10th the original formula amount of cocaine and by 1903 he removed cocaine from Coca-Cola by using “spent” coca leaves leftover from the cocaine extraction process. Guys today we will see that what will happen if we put mentos in coke!!! With all of the tiny bumps on a Mentos, it is easy to see how you have yourself a geyser! I had not at that point thrown up in about 15 years, so this was bizarre. Prepare three groups of crushed and cut Mentos like this one. To determine the reaction time of each geyser, watch the videos for each trial and note the time for when the geyser starts and when it stops.
