If you’ve ever wondered why Diet Coke and Mentos react so strongly to one another, well, wonder no more. The buoyancy of the bubbles and their growth in size will quickly cause the bubbles to leave the nucleation site and rise to the surface of the soda.В  Bubbles will continue to form on the porous surface and the process will repeat, creating a nice foamy result.
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.В  If you add enough caffeine, you will see a difference, but the levels required here to see a significant difference are on the order of the amount that would kill you if you actually consumed the beverage. As an aside, while I personally have never tried drinking Diet Coke and eating Mentos, I have had a similar experience after taking a new kind ofВ  multivitamin I’d not tried before, combined with drinking a 16 ounce container of Dr.
Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. Coffey and company discovered that the ingredients in the Mentos and Diet Coke and, more importantly, the structure of the Mentos, allow carbon dioxide bubbles to form extremely rapidly. Each Mentos candy has thousands of small pores on its surface which disrupt the polar attractions between water molecules, creating thousands of ideal nucleation sites for the gas molecules to congregate.
In addition to that, the gum arabic and gelatin ingredients of the Mentos, combined with the potassium benzoate, sugar or (potentially) aspartame in diet sodas, also help in this process.
Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. 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 the typical 2-liter bottle of soda generally used for these sorts of Diet Coke and Mentos reactions. Keep adding baking soda and vinegar as long as you want – as long as you keep adding, it will keep bubbling!
Make sure you are doing this experiment in a place where you won't get in trouble for getting Diet Coke everywhere…and we do mean EVERYWHERE. Stand the Diet Coke upright on a flat surface – might want to use a plate or something to keep it standing upright. Put your funnel or tube on top of the bottle so you can easily drop the Mentos in all at the same time (about half the pack is a good amount). If you've done it properly a huge geyser of Diet Coke should come flying out of the bottle, it's a very impressive sight. Although there are a few different theories around about how this experiment works, the most favored reason is because of the combination of carbon dioxide in the Diet Coke and the little dimples found on Mentos candy pieces. Dropping something into the Diet Coke speeds up this process by both breaking the surface tension of the liquid and also allowing bubbles to form on the surface area of the Mentos.

The experiment works better with Diet Coke than other sodas due to its slightly different ingredients and the fact that it isn't so sticky. For the floating ketchup packet - simply screw the cap on the bottle and squeeze the sides of the bottle hard.
Once it is consistently floating, make sure the bottle is filled to the top with water, and then cap it tightly.
SCORM packages are zip files that can be integrated in any LMS (Learning Management System) that supports the standard (Moodle, Blackboard, …) and that can be used for presenting multimedia content and as assessment tools. John Pemberton’s, bookkeeper, Frank Robinson, stemming from the two key ingredients: extracts from the coca leaf and kola nut.
Tonya Coffey of Appalachian State University and her physics students published a paper on the phenomenon in the American Journal of Physics. In non-science speak, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. In these cases, the ingredients end up lowering the surface tension of the liquid, allowing for even more rapid bubble growth on the porous surface of the Mentos—higher surface tension would make it a more difficult environment for bubbles to form.
You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water.
The faster it sinks, the faster the reaction can happen, and a faster reaction creates a bigger geyser; a slower reaction may release the same amount of foam overall, but will also create a much smaller geyser. Gases are less soluble in liquids with a higher temperature, so the warmer your soda is, the bigger your Mentos-induced geyser will be. Today, we’re giving you a list of fun and exciting science experiments that you can do at home. These explanations will help you better understand science and hopefully give you inspiration to create your own fun experiment!
When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution. It doesn't get released from the liquid until you pour it into a glass and drink it, some also gets released when you open the lid (more if you shake it up beforehand).
Mentos candy pieces are covered in tiny dimples (a bit like a golf ball), which dramatically increases the surface area and allows a huge amount of bubbles to form.
Diet Coke that had been bottled more recently worked better than older bottles that might have lost some of their fizz sitting on shop shelves for too long, just check the bottle for the date.

If the ketchup packet sinks when you squeeze it, and floats when you release it, congratulations, you're ready to show it off to amazed friends and family. The magic ketchup should sink when you squeeze the bottle and float up when you release it. Thus, you can integrate your Virtual Excursion in Moodle and other LMSs by downloading it as SCORM. This is another reason Mentos works so much better than other similar confectioneries: The candies are fairly dense objects and tend to sink rapidly in the soda. This is because the gases want to escape the liquid, so when you drop the Mentos in, the reaction happens faster. In fact, the level of acidity in the Coke before and after the Mentos geyser does not change, negating the possibility of an acid-based reaction—though you can make such an acid-based reaction using baking soda. When you do create your own experiment – please send us a note and tell us about it - it could be featured on our blog!
This usually describes how things float in liquids, but it can also describe how things float or sink in and various gasses.
Bubbles will continue to form on the porous surface and the process will repeat, creating a nice, foamy geyser. If you crush the Mentos, so it doesn’t sink much at all, you won’t get a very dramatic reaction. As we know bubbles float, and the bubble in the ketchup sometimes keeps the heavy packet from sinking. That causes the bubble to get smaller and the entire packet to become MORE DENSE than the water around it and the packet sinks.
When you release the pressure, the bubble expands, making the packet less dense (and more buoyant) and, alas, it floats back up.
