Diet soda and mentos trick
Be sure that the soda bottles are all the same brand and type. If you want a more specific measurement, use chalk to mark off 1-foot increments on the brick wall before you drop the Mentos into the bottle of soda. The simplest method is to let the unopened bottle sit in the sun for several hours. Make comparisons, create a chart with your data, and draw some conclusions. The thing that makes soda bubbly is invisible carbon dioxide (CO 2 ), which is pumped into bottles at the bottling factory using lots of pressure. Place one bottle of Diet Coke in the refrigerator and let it sit overnight. Open the bottle and dip the thermometer down into the soda. Load seven Mentos into your paper roll and drop them into the soda. Measure the height of the geyser by counting the number of bricks that are wet once the geyser stops. A roll or box of Mentos chewy mints (stick with the standard mint flavor for now). Does warm soda shoot up higher than cold soda. The reason why Mentos work so well is twofold—tiny pits on the surface of the mint, and the weight of the Mentos itself. This has to be the number one question everyone asks about this experiment. Remember that 1 liter is equivalent to 1000 mL. Use your data from the previous test to determine the standard number of Mentos to use for this test. Why do Mentos turn ordinary bottles of diet soda into geysers of fun. There are two safe ways to warm the other bottle of soda. What is the effect of temperature on the height of the geyser. These tiny pits act as nucleation sites—perfect places for CO 2 bubbles to form. Soda pop is made of sugar or artificial sweetener, flavoring, water, and preservatives. The answer is a little more complicated than you might think. The gas released by the Mentos literally pushes all of the liquid up and out of the bottle in an incredible soda blast. When you pull your finger out of the way, all seven Mentos should fall into the bottle at the same time. MENTOS Diet Coke Geyser - The Original Experiment. While science teachers have been dropping candies and mints into 2-liter bottles of soda for years in an effort to release all of the dissolved carbon dioxide, the Mentos and Diet Coke reaction became world famous in 2005. Check to make sure your measuring scale is in place (counting bricks or using an alternative scale against the wall). The brand of soda is the only thing that changes (the variable). These are CO 2 bubbles leaving the soda and attaching themselves to the object. Drop an object like a raisin or a piece of uncooked pasta into a glass of soda and notice how bubbles immediately form on the surface of the object. 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 Mentos Trick All you do is drop a tube of Mentos candies into a bottle of soda. Immediately record the data for the cold soda test. Plastic bottles seem to produce a better effect than glass ones, but really, either works. You can also place the bottle of unopened soda in a bucket of warm water.
When you open the container, the bubbles quickly rise to the top pushing the liquid out of the way. To enforce the fairness factor, you must stick with one brand of soda for the entire test. If you shake a bottle or can of soda, some of the gas comes out of the solution and the bubbles cling to the inside walls of the container (thanks to tiny pits and imperfections on the inside surface of the bottle called nucleation sites ). For additional shipping or quantity options, or to learn more, visit the Mentos Geyser Tube product page. Launch a Mentos soda geyser 30 feet in the air with the Geyser Tube. Using any more than seven Mentos is just a waste, according to these soda-soaked science enthusiasts. The key is to keep every launch fair and to make sure the only variable is the temperature of the soda. This bubbling process is called nucleation, and the places where the bubbles form, whether on the sides of the can, on an object, or around a tiny grain of salt, are the nucleation sites. Position the bottle on the ground so that it will not tip over. What is the best number of Mentos to use to make the highest-shooting geyser. While you may get a slightly higher fountain from a diet drink compared with a sugary one, the real determining factor is the size and shape of the bottle. A 2-liter or 1-liter bottle works much better than a smaller bottle. Mentos stack neatly onto each other, leaving very little extra space, so they displace liquid better than other candies. Each bottle will receive a different number of Mentos. However, the trick works just fine with regular soda. Each Mentos mint has thousands of tiny pits all over the surface. Other methods include using a large plastic test tube to hold the Mentos or using my Geyser Tube toy invention, which was created to solve this very problem. Have you ever wondered whether or not the Mentos trick works with regular Coke. Again, the choice of diet over regular soda is purely a preference based on the fact that erupting regular soda becomes a sticky mess to clean up because it contains sugar. As soon as the Mentos hit the soda, bubbles form all over the surfaces of the candies and then quickly rise to the surface of the liquid. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos. Drop Mentos into a bottle of soda and run away from the 20 foot geyser. This activity is probably best done outside in the middle of an abandoned field or on a huge lawn. How does generic soda stack up against the big name brands. However, you can use seltzer water (very easy cleanup) or any soda. Subtract the remaining amount of liquid from the original volume of the bottle to calculate the volume of the geyser. The goal is to drop all seven Mentos into the bottle of soda at the same time (which is trickier than you might think). Many soda geyser-ologists believe that seven Mentos produce the highest-shooting geyser. You could use a beaker or a graduated cylinder to measure the remaining liquid in milliliters. For example, adding salt to soda causes it to foam up because thousands of little bubbles form on the surface of each grain of salt. Place the second bottle in a place where it can reach room temperature overnight. To make any of these tests meaningful, you need to find a way to measure the height of the eruption. Why diet soda for the Mentos and diet soda geyser. Drop one Mentos into the first bottle and record the height by counting the wet bricks (or set up your own scale behind each soda bottle). Then make comparisons, create a chart with your data, and draw some conclusions. Again, make sure all of the soda is at the same temperature because temperature plays an important role in the reaction. Never use a stove or microwave to heat a bottle of soda.
