The pits on Mentos candies are referred to as "pockmarks." These tiny dimples or pits are created during the manufacturing process and play a key role in the candy's interaction with Carbonated Beverages. When Mentos are dropped into soda, the pockmarks facilitate rapid gas release, leading to the iconic geyser effect.
Mentos, the freshmaker!
Any carbonated soda with bubbles should react since the reaction is caused by a buildup of carbon in tiny pits on the surface of uncolored/unwaxed mentos. If you use a waxed/smooth version of the candy it will not have a good reaction to ANY soda, because the pits will be filled or fewer.
because they are mean
The force generated in a Coke and Mentos experiment primarily comes from the rapid release of carbon dioxide gas when the Mentos candies are introduced into the soda. The surface of the Mentos is covered with tiny pits that facilitate nucleation, allowing gas bubbles to form quickly. This rapid gas expansion creates a vigorous eruption, propelling the soda outward. The force of the eruption can vary based on the type of soda, the number of Mentos used, and environmental factors.
The bubbling action that occurs from dropping a mentos into a diet coke occurs because the high quantities of carbon dioxide held within the soda react with the candy. The candy's shell is actually comprised of many extremely small pits in which the CO2 forms in a process called nucleation. The diet coke has 7 times more CO2 than can be easily dissolved into water at regular atmospheric pressures. Increasing the pressure on the liquid allows it to dissolve more CO2. This CO2, once released from its high pressure tank is trying to escape its watery prison. With the addition of the mentos, the opportunity of a lifetime presents itself, and all of the CO2 escapes the water in a short amount of time often with explosive results. The only difference that could be ascertained would be that the fruit mentos lack the same number of pits available with the mint mentos, resulting in a slower release of CO2, which in turn causes a smaller explosion.
Diet Coke is the most reactive soda with Mentos due to its higher concentration of carbon dioxide and lack of sugar to hinder the reaction. The carbon dioxide bubbles in the Diet Coke attach to the microscopic pits on the Mentos surface, creating a rapid release of gas that results in a large fountain.
There are chemicals in the soda called Potassium Benzoate and aspartame that react with other chemicals in Mentos like the gelatin and Arabic gum.

The surface of a Mentos is not smooth; it has microscopic pits, or nucleation sites, on it. These pits cause the CO2 in Diet Coke to come out of solution very quickly at the bottom of the bottle. The result is rapids release of the CO2 and foam in an explosion. This is actually the physical change that occurs. Due to the addition of caffeine, potassium benzoate, and aspartame with the CO2 in the Diet Coke, the reaction is much greater--this would be the chemical change.The Mythbusters did an entire show devoted to discovering why this happens. See the related link below.
The soda is packed with loads of bubbles that want to get out of the liquid. To do so they need to form bubbles around something like a spec of dirt or a tiny dent in the bottle. That's why you see bubbles forming from the same places in glasses of soda.A mentos has a very rough surface (on a microscopic scale) so when you put it in all the millions of bubbles suddenly form on the mint creating loads of gas which has to go somewhere. So it blasts out the top of the drinks bottle. It works with any rough surfaced material like chalk, not just mentos.
The flat spots on a CD are called pits and lands. These pits and lands are etched onto the surface of the CD to store digital information in the form of binary code.
