Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. Place an index card over the opening of the test tube or end of the paper tube to hold the candies in the container. 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.
Doing this part can be tricky if you don't have a specially designed geyser tube, I recommend buying one from a local store such as Natures Discoveries NZ or online. But because they are smooth and clean, the activation energy is still relatively high, and the process is slow.
Would a plastic water bottle be enough to hold Coke and Mentos together after I shake it? In non-sciency terms, basically, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos.
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. There's a lot of carbon dioxide dissolves in the soda, which gives it its fizz.
This is another reason Mentos works so much better than other similar confectioneries: This is not the case either. The easiest way to do this is to stack them in a test tube narrow enough to form a single column. Carbonated sodas contain elevated levels of carbon dioxide under pressure.
Normally, this process is relatively slow, because the activation energy for this process is high. The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites.

To keep my streak alive, I attempted, vainly, to keep the contents of my stomach down. Is there a chance of the bottle bursting? Have fun! Peoples' Poet I'm using cans of Diet Coke. Can the resulting explosion no other word for it They also compared reactions using other fizzy liquids such as caffeine-free and sugary colas, as well as soda water and tonic water.
Instead, the vigour of the jets depends on various factors that affect the growth rate of carbon dioxide bubbles. When the Coke and Mentos explodes, what is the chance of a piece of Mentos bopping someone in the face? Make sure you are doing this experiment in a place where you won't get in trouble for getting Diet Coke everywhere.
Mentos are fairly dense objects and so tend to sink rapidly in the liquid. Update 2: In fact, the level of acidity in the Diet coke and mentos 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.
Although there are a few different theories around about how this experiment works, the most favoured reason is because of the combination of carbon dioxide in the Diet Coke and the little dimples found on Mentos candy pieces. It has also been shown that a wide variety of beverage additives such as sugars, citric acid, and natural flavors can also enhance fountain heights.
Experiments in a edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke.
They were inspired by a MythBusters episode that, according to the paper"did a wonderful job of identifying the basic ingredients in this reaction 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.
Qrius delivers fresh, immersive writing that answers the question 'Why should I care? The bubbles expand as they rise.It’s been called the “vinegar and baking soda” reaction for a new generation. 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 Video Duration: 2 min.
Mentos reacts strongly to all carbonated drinks owing to some of its molecular properties. The article provides a brief of some of the causes of such a strong reaction.

Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. The reaction is so intense, you can make a rocket propelled by.
· How to Make a Diet Coke and Mentos Rocket. Dropping Mentos into a bottle of diet soda causes a physical reaction: as they fall through the soda, the Mentos candies break the bonds between the carbon dioxide and water (the combination that 75%().
The Diet Coke and Mentos geyser is the result of a physical process rather than a chemical reaction. There's a lot of carbon dioxide dissolves in the soda, which gives it its fizz.
