But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction are there, but that they are simply rearranged. It also means changing some factors may cause a larger or smaller physical reaction to take place. Background A carbonated beverage is packed full of dissolved carbon dioxide gas, which forms bonds with water.
While the soda is in the bottle, the gas is kept in solution by the bottle's pressurized conditions. When you pour some soda into a glass, some gas escapes and forms foam, but most stays trapped by the surface tension of the water.
But all those gas bubbles want to escape, making it no wonder that soda makes you burp! To create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide's bonds with water in the Diet Coke must be broken. A Mentos candy can help with this. Although the candy may look smooth, if you looked at it under a microscope you'd see tiny bumps coating its entire surface. This rough surface allows the bonds between the carbon dioxide gas and the water to more easily break, helping to create carbon dioxide bubbles and cause the classic eruption.
The speed at which the Mentos falls through the soda can affect how large the eruption is, and this can be tested by comparing whole with crushed Mentos, the latter of which are less dense. On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. An adult may help you cut up the candies. What does the inside of the candies look like? Tape the tube together on the side.
Make sure that the bottle is on a level surface and stably standing straight. Why do you think all of this is important? Line up where the opening of the bottle is with the opening of your cartridge. Quickly pull out the flat index card, releasing the Mentos candies into the bottle.
Then step back without tipping the bottle over or disturbing the reaction. About how high did the eruption go? This is likely for two reasons. First, the act of drinking soda releases quite a bit of the carbonation in it, limiting the possible effect.
On a similar note, birds will not have their stomachs blow up if you feed them dried rice or Alka-Seltzer. Within a couple minutes of taking the vitamin after eating and consuming the Dr. Pepper , I noticed I started to feel like I was going to throw up.
I had not at that point thrown up in about 15 years, so this was bizarre. To keep my streak alive, I attempted, vainly, to keep the contents of my stomach down.
Ultimately, the pressure became too much and I threw up a ton of foam red, like the multivitamin coating. It seems likely that the surface of this vitamin must have been porous and it did most likely also contain at the least the gum arabic. As I had not chewed it before swallowing, it found its way to the still somewhat carbonated liquid although much less so having drunk it and produced enough foam to overfill my already somewhat full stomach from dinner. So let that be a lesson to you.
Certain types of multivitamins and soda also produce a nice foamy reaction. While there were initially different versions of Coca-Cola being sold depending on the manufacturer, of which there were three primary businesses Pemberton had sold the formula to , all the versions contained cocaine, with some estimates of up to nine milligrams of cocaine per serving.
This still resulted in Coca-Cola having trace amounts of cocaine though. The company that prepares this extract, Stepan Company in Maywood, New Jersey, also legally makes cocaine for medicinal purposes.
While in the beginning carbonation was added to drinks because it was thought it was beneficial to the human body, today carbonation is added for very different reasons, namely, taste and shelf life. Carbonating beverages, introducing CO2 into the drink mix under pressure, makes the drink slightly more acidic carbonic acid , which serves to sharpen the flavor and produces a slight burning sensation.
And will it happen if you put other stuff in soda pop? Place a straw in the soda and look at the straw from the side. What to expect. Bubbles will form on the straw and very quickly and completely cover the pipe cleaner. What's happening in there? Why do the bubbles form on the different things you put in the soda?
The carbon dioxide molecules collect on these places and form bubbles which rise to the surface. Make a Mentos-and-Soda Fountain! First, make a tube for the Mentos. Cut a piece of paper so that it is as wide as a roll of Mentos.
Open the pack of Mentos and place all of them in the tube. Now, make a Mentos-and-soda fountain!
