Pub bonbons Mentos - vid. Diet Coke and Mentos eruption. A 2- litre (0. 4. US gal) bottle of Diet Coke just after Mentos were dropped into it. From left to right: action of five Mentos candies (per bottle) with Perrier, classic Coke, Sprite and Diet Coke. A Soda Geyser (alternatively Diet Coke and Mentos geyser or Mentos eruption) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. At the end of the 1. Wintergreen Lifesavers increased the size of the mints and they no longer fit in the mouth of soda bottles. Science teachers found that Mint Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. The experiment became a subject of the television show Myth. Busters in 2. 00. The addition of the Mentos leads to the rapid nucleation of carbon dioxide gas bubbles precipitating out of solution. Carbonated sodas contain elevated levels of carbon dioxide under pressure. The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released.

Something amazing happens when Mentos and diet soda mix. Under these conditions, carbon dioxide begins to precipitate from solution, forming gas bubbles. Normally, this process is relatively slow, because the activation energy for this process is high. The activation energy for a process like bubble nucleation depends on where the bubble forms. It is highest for bubbles that form in the liquid itself (homogeneous nucleation), and lower if the bubble forms on some other surface (heterogeneous nucleation). When the pressure is released from a soda bottle, the bubbles tend to form on the sides of the bottle. But because they are smooth and clean, the activation energy is still relatively high, and the process is slow. The addition of other nucleation sites provides an alternate pathway for the reaction to occur with lower activation energy, much like a catalyst. For instance dropping grains of salt or sand into the solution lowers the activation energy, and increases the rate of carbon dioxide precipitation. The physical characteristics of Mentos (surface roughness, easy dissolution into the liquid, etc.) have the effect of drastically reducing the activation energy for carbon dioxide bubble formation, so that the nucleation rate becomes exceedingly high. The activation energy for the release of carbon dioxide from Diet Coke by addition of Mentos has been found to be 2. J mol. 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. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in water. Given that there are plenty of hilarious and amazing Mentos and Diet Coke videos out there. Mentos Geyser Science Project;. You know that dropping Mentos into Diet Coke causes a geyser to erupt. That is a fun demonstration. Pub Vittel par Gotainer. Par Odilederey. 00:31 Pub Banga 1975.

Leads to the classic Mentos and Diet Coke eruption. The speed at which the Mentos falls through the Diet Coke can affect how large the eruption is. Journal of Chemical Education. Kuntzleman, Laura S.
