Confectionery structure itself. The reason why a lot of coke in the presence of carbon dioxide, because the production process uses a high pressure, the moment open the bottle, the pressure is reduced, whereby carbon dioxide is released from the coke in. However, this process is usually slow, careful observation can be found most of the bubbles generated from the sides of the bottle, this is because the gas produced typically require either deposited on a surface of some of the particles, this phenomenon became nucleation. many people have tried the chopsticks into the child might carbonate drinks inside, this time around will be attached to the bubble chopsticks, because chopsticks provide a new surface, become gases "nuclear." If you put Mentos zoom times, you can see these sugars rough surfaces there are a lot of holes, these porous structure makes Mentos into a good gas "core", a lot of carbon dioxide can be attached to the surface of the sugar. and Mentos are denser than water, added to the list immediately sink bottom, rapidly produce gas at the bottom of the top of the liquid ejection favor.
Candy surfactant. The same porous structure of salt or sugar crystals, although eruptions can produce results, but far less than the ability of Mentos, which really Mentos candy and related components. In Mentos sugar often used in the production process to the two substances, a gelatin, gum arabic is another, there is a strong hydrogen bonding between the natural surfactants are water molecules, bubbles must be tightly coupled to open the top of the water molecules, break the siege in order to be released. gelatin and gum arabic glycoprotein contain ingredients, which a large number of C = O bond, NH and OH bond bond will destroy the hydrogen bonding of water molecules themselves, which can reduce the effect of surface tension, which is said that the new generation of the bubble pack fence is greatly reduced, so as to establish an environment conducive to the bubble generation. |
