the caffeine, potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatin and gum Arabic ingredients of the Mentos, all contribute to the jet effect (Coke also works, but is less effective because there is no aspartame). The physical structure of the Mentos is the most significant cause of the eruption due to nucleation. The surface of the mint Mentos is littered with many small holes, allowing CO2 bubbles to form very rapidly and in great quantity, in turn causing the jet of foam.
Diet Coke tends to produce a more dramatic explosion than regular Coke due to its use of artificial sweeteners, which are less dense and can create a larger volume of bubbles when the carbonation is released. Additionally, the absence of sugar means that the bubbles can expand more rapidly, leading to a higher fountain effect when the can is opened. The physical reaction with Mentos, which is often used in demonstrations, is also enhanced by the lighter composition of Diet Coke.
The volume of the liquid in which Mentos are dropped affects the intensity and duration of the reaction with Coke. In a larger volume, the gas produced can disperse more, leading to a less dramatic eruption. Conversely, in a smaller volume, the reaction is more concentrated, resulting in a higher and more explosive geyser as the carbon dioxide rapidly escapes. Thus, a smaller volume typically leads to a more impressive visual effect.
2-5 seconds, be ready to clean up a BIG mess
The regular coke contains a higher amount of solute (sugar, corn syrup) compared to the diet version which uses concentrated artificial sweetener. The slightly-higher viscosity (thickness) of the regular Coke slows the nucleation of carbon dioxide on the surface of the Mentos candy. The thickness also means that it takes more force to lift the liquid out of the bottle (less height to the gas-driven foam fountain).
Basically, you are witnessing the Surface Effect. Carbon Dioxide forms bubbles. Diet Coke has more carbon dioxide than other regular sodas. The surface of the "mento" is jagged and filled with nooks and crannies. The Carbon Dioxide finds all of these holes and fills them with bubbles. Since the Mentos are heavy, they drop to the bottom of the bottle, forming bubbles all the way down. This is what causes the fast and furious explosion out of the top of the Diet Coke bottle.
Yes. For some reason Diet Coke appears to work particularly well, though the difference isn't overwhelmingly huge (maybe a factor of two; certainly not a factor of ten). The difference is probably more due to the "diet" part (less sugar = less dense) than the "Coke" part.
It doesn't. However, most geyser-makers prefer diet soda over regular because the sugar substitute is not sticky (sugar, of course, is very sticky) and therefore does not make as much of a mess for the ones standing nearby or cleaning up after! out during the explosion.Answer:when i tried to see if coke or Pepsi max would Not necessarily The reason for the geyser is not a chemical reactionause the diet soda doesn't have nearly as sticky residue if not cleaned up properly. Because it has less sugar.
Yes
Diet coke is less dense than regular coke.
Coke is added to the blast furnace instead of coal because coke is a purified form of coal that has higher carbon content and produces less impurities when burned. This helps maintain the purity of the iron being produced in the blast furnace. Additionally, coke generates higher temperatures, promoting better efficiency in the iron-making process.
diet coke has acid in it just less than coke diet coke does not have sugar either which coke and coke zero has
