l Put the index card on top of the tube loader and turn the tube upside down. 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. And it’s a great way to learn about chemical reactions. The Egg Drop Challenge Do you want to learn about physics? aq Write down what you think will happen when placing the Mentos in the soda. Be ready. Now it’s time to actually run the experiment, but first, we need to make a hypothesis. Pre-existing bubbles provide a way for the reaction to occur without requiring bubbles to form within the liquid itself (homogeneous nucleation). Alaska has something for everyone. 2 Compare your notes on the experiment to the control group. Under these conditions, carbon dioxide begins to precipitate from solution, forming gas bubbles. Do you want to understand the effects of weight,…, How to Make a Tornado In a Bottle We love learning about the weather. Why does it work better with … Open the soda bottle, set it down and write down what you observe about it. The experiment became a subject of the television show MythBusters in 2006. ) [19] In some cases, dissolved solids that increase the surface tension of water (such as sugars) also increase fountain heights. You want the candies going in the bottle and not falling over the side. ), Shaka Zulu – Famous Ancient African People, Tony the Tiger Fun Facts (He’s Grrrrreat!). ⇀ So, if you want some quick and easy fun, get some paper towels because we’re about to make a sweet mess. The activation energy for the release of carbon dioxide from Diet Coke by addition of Mentos has been found to be 25 kJ mol−1. It’s fun to learn how rain…, Why Did Russia Sell Alaska? [10] When the pressure is released from a soda bottle upon opening it, dissolved carbon dioxide can escape into any tiny bubble located within the beverage. So, if you want some quick and easy fun, get some paper towels because we’re about to make a sweet mess. Well, it’s probably not pretty. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. It really only takes a few minutes to setup the mentos and coke volcano experiment. [19][12][14][17] It has been claimed that gelatin and gum arabic in the Mentos candy enhance the fountain,[12][14][24] but experiments have shown that these candy additives have no effect on the fountain. But when it…, Christmas Facts For Kids Did you know that more than two billion people celebrate Christmas around the world? Christmas Facts For Kids (Fun & Festive! Please support Cool Kid Facts by emailing or sharing! CO The conversion of dissolved carbon dioxide to gaseous carbon dioxide forms rapidly expanding gas bubbles in the soda, which pushes the beverage contents out of the container. The reaction happens fast, so don’t have your face over the bottle. Write down what happened when you dropped the Mentos in the coke. + [7][8] Experiments carried out at altitudes ranging from below sea level in Death Valley to the summit of Pikes Peak have demonstrated that the reaction works better at higher elevations. Steve Spangler's televised demonstration of … It really only takes a few minutes to setup the mentos and coke volcano experiment. But making soda explode is fun. There really aren’t that many supplies you need to make a mentos and coke volcano. This will count as your control group. Carbonated sodas contain elevated levels of carbon dioxide under pressure. The addition of the Mentos leads to the rapid nucleation of carbon dioxide gas bubbles precipitating out of solution:[19][20][21][2]. Science teachers found that Mint Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. − 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.
