  • 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. 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.

  • I wonder how a nitrogenated beverage would compare, since nitrogen bubbles are inherently smaller?

  • 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. The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres.

  • The startling reaction explained define between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally defie a scientific explanation. What Doesn't Work 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.

Still there, or gone to get coffee???

For our finale, I took the kids outside to play some more with matter. Measurements of the pH of the Coke before and after the experiments showed that its acidity did not change, ruling out the idea that a simple acid-base reaction drives the fountains.

Slowly and carefully open a new bottle of Diet Coke. Then, I quizzed them on whether that object was a solid, liquid, or gas.

Carbonated sodas contain elevated levels of carbon dioxide under pressure. The reacttion is caused by a physical reaction, rather than any chemical reaction. 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. Archived from the original on May 7,

Wikimedia Commons. They suspected other compounds dissolved in the drinks might be affecting fountain coks, so they carried out further tests on these compounds in isolation. Carbonated sodas contain elevated levels of carbon dioxide under pressure. We defined a gas. Later, after I was no longer teaching summer camp, some of my friends who were teaching their children at home asked me to be a "guest teacher" for their preschool and kindergarten age kids.

I also used the special test tube below:. The carbon dioxide molecules collect on these places and form bubbles reaction explained define rise to the surface. They also compared reactions using other fizzy liquids such as caffeine-free and sugary colas, as well as soda water and tonic water. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle's base.

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. Temperature is a really important factor in this experiment, and it is rarely mentioned in tutorials and explined. Then when bubbles are released in your stomach, your stomach can expand a bit. Size Matters Another factor that contributes to the size of the geyser is how rapidly the object causing the foaming sinks in the soda. 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 physical characteristics of Mentos surface roughness have the effect of drastically reducing the activation energy for carbon dioxide bubble formation so that the nucleation rate becomes exceedingly high. Davenport, Victoria I.

PMC Science teachers found that Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. Now sprinkle in some granulated sugar. On your glass, there are fine imperfections which act as nucleation points where the bubbles can form and escape. The physical reaction that drives the eruption also causes a chemical reaction that slightly increases the pH of the soda.

When you are ready, remove the card and let all the Mentos drop into the soda at once and quickly move out of the way. LOG IN.

The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in the water. Kuntzleman, Laura S. Thus the Coke and Mentos reaction is a physical one, not a chemical reaction. Size Matters Another factor that contributes to the size of the geyser is how rapidly the object causing the foaming sinks in the soda. No fizz.

Home Archives About Contact. Guinness World Records. Today I Found Out. 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. Diet Coke and Coke Zero tend to go a bit higher than regular soda, because they have a little more carbonation and the sweeteners help make the reaction a little bigger. This is because the gases want to escape the liquid, so when you drop the Mentos in, the reaction happens faster.

Rough candy

They experimentally tested the reaction using different seeding objects, such as different candies, sand, rock salt and dish soap. No nucleation sites. Well, a lot of the fizz goes away as you drink.

Slowly and carefully open a new bottle of Diet Coke. If you could look at the straw, pipe cleaner, and Doke with mentos diet coke reaction explained define super-strong microscope you would see that they have tiny dents, scratches, and bumps on them. Investigating further, it was found that when the substances were dissolved in water, the bubbles produced were smaller. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites.

Nucleation sites can be scratches on a glass, the explainde of mentos diet coke reaction explained define finger, or even specks of dust — anywhere that there is a high surface area in a very small volume.

Wouldn't any rough surface work with any fizzy drink? All the carbon dioxide in ddfine soda — all that fizz — is squeezed into the liquid and looking for a way out. That makes it not only sweet but also covered with lots and lots of nucleation sites. We made a video too….

Help Learn to edit Community portal Recent changes Upload file. That's the great thing about science. Carbonated drinks get their fizz from dissolved carbon deine, which is pumped into the bottles at high pressure to make it dissolve. The proposed explanation for this is that the dissolved compounds may actually be affecting how the bubbles themselves behave, and it is this combined with factors relating to surface tension that influences fountain height. They suspected other compounds dissolved in the drinks might be affecting fountain height, so they carried out further tests on these compounds in isolation.

Experiments in a edition of the Discovery Define 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. Measurements showed that the surface tension in water containing the sweetener aspartame is lower than in sugary water, explaining why Diet Coke creates more dramatic fountains than sugary Coke.

  • It turns mento Mentos were the best seeders for the reaction. 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.

Bibcode defie Natur. Another factor is that the coatings of Mentos contain gum arabic, a surfactant that further reduces surface tension in the liquid. But there have been no rigorous scientific studies of the reaction until now. As the carbon dioxide is less soluble at lower pressures, it starts to leave the drink in the form of small bubbles. While a Mentos candy contains millions of cavities, it is likely that only aboutcavities actively nucleate bubbles on any single Mentos candy placed in a carbonated beverage.

Fizzy liquids

When the bubbles are smaller, there is a greater surface area for the carbon dioxide still dissolved in the solution to escape into, so the degassing of the carbonated drink happens faster — giving a higher fountain. Sugar-sweetened drinks tend to be more viscous, which likely slows bubble formation, leading to smaller fountains than for their diet counterparts. The physical characteristics of Mentos surface roughness have the effect of drastically reducing the activation energy for carbon dioxide bubble formation so that the nucleation rate becomes exceedingly high.
