some people say that it does when you put it in coke or a carbonated drink... <heather>

Because the chemicals in diet coke react with the chemicals in the mentos, Normal coke has the same chemicals that mentos has, that is why you need to have a positive and negative to react, Normal coke and mentos is positive and positive.

it is not a chemical but a physical one

when the mentos hits the surface of the coke, the compressed carbon dioxide forms bubble on the surface of the mentos. and it is released into the air and pushes the coke out with it.

also, water molecules connect tightly together creating surface tension that is quickly broken down by the gelatine and the gum Arabic from the mentos

the experiment also works on lots of other things however, it works especially well on mentos because mentos have a lot of nucleation sites. these are areas that co2 can create bubbles. they can be scratches on a surface or anything. the compressed co2 from the soft drink then create thousands of bubbles in each nucleation site.

I did that in Science Camp once. When you put mentos in a soda bottle the soda will shoot up creating a little shoot up of soda. Its very fun!

why dose a fizzy drink and a mint cause an explosion

This reaction is an example of the dissolved gas (carbon dioxide) within diet coke, quickly bubbling out of solution as a result of Mentos being dropped in.

The surface of Mentos candies are high in surface area, and are bumpy and pitted. Bumpy surfaces tend to "seed" bubbles out of carbonated drinks. What is meant by "seeding" this means is that when a gas is dissolved in a solution, it remains within the solution in microscopic bubbles. If there is an area where these microscopic bubbles can gather, they will do so to create a larger bubble (due to the hydrophobic effect). Areas that promote these microscopic bubbles to gather are called "seeds". Eventually the bubble will be too large to simply stay in solution and begin to rise to the surface, often as a visible tiny bubble. This is the same reason why after pouring yourself a glass of your favorite carbonated beverage, you may see small bubbling trails seemingly coming from the side of the glass out of nowhere. The "source" or origin of the bubbling is likely a small imperfection of the glass seeding bubbles.

When you drop the Mentos in, the carbon dioxide bubbles in the soda becomes seeded all over the entire surface of the candy's surface. Due to its high surface area, it seeds millions of bubbles at once, creating rapid gas release from solution. Additionally, gum Arabic coating the surface of the candy acts as a surfactant, decreasing surface tension of the bubbles on its surface. Low surface tension also helps bubbles grow quickly. Aspartame (the artificial sweetener in diet coke) also works as a surfactant in solution, further decreasing surface area and increasing bubbling. Finally, Mentos are also fairly dense and sink rapidly, quickly creating bubbles that seed further bubbles as they rise, creating an exponential effect as the bubbles rise to the surface, as the bubbles are given more time to gather more bubbles as they rise.

If you like explosions, try this!

pepsi and coke, though coke works better

because the mentos has microscopic bumps on its shell, it traps the carbon dioxide and makes it escape a lot quicker than normal. that's why there is that white foamy stuff on the top, because the carbon dioxide(the fizziness) is escaping so quickly.

Pressure build up makes soda explode.

Sniper is the best gum in the whole world

well, i like 5 gum, and mentos gum :) xx

Sort of, it doesn't explode but shoots up. Myth Busters did a show on this to find out if it was true. They measured the amount of soda that shot up out of the bottle. It didn't explode, but did shoot up.

If you accept the definition of explosion is a violent release of energy through a chemical reaction, then yes they do explode. The Mentos react violently when released into coke and create a spectacular reaction.

There are two grams of sugar per 1 mentos. (:

No mentos only explode in diet it pop if you try regular you will be wasting your time

First off, make sure you do not open the bottle until you are 100% ready for the experiment. You need to keep all of the carbonation and pressure inside the bottle. If you want it to be 100% foolproof then you can buy something called a "Mentos Geyser Tube". It's hard to describe but you can look it up to get an in-depth description. Just make sure that you wear clothes that you don't mind getting dirty. Diet Coke works best for this experiment. If you want to do other mini experiments then you can try using any other porous candy like altoids or even alka seltzer if you wanted to. Just experiment and you'll find what works best, and what doesn't. Have fun!! :)

Yes because all soda has carbonation in it. The rough outside of a Mento has something called a nucleation site. the carbon forms gas bubbles while it sinks. Then, the carbon bubbles escape and they reach the top and give you a fountain.

Not much. The chemicals and sugar in Mentos kick all of the carbon dioxide is soda loose at one time- so it foams up in a fountain- but flat soda has already lost most or all of the CO2.

A geyser

I'm not totally sure, but I'm pretty confident that it's actress Sophina Brown from Numbers.

Mento.

"Why does this work? While there is considerable debate over how and why, here's the hypothesis: Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. In order to form a new bubble, or even to expand a bubble that has already formed, water molecules must push away from each other. It takes extra energy to break this "surface tension." When you drop the Mentos into the soda, the gelatin and gum Arabic from the dissolving candy break the surface tension. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. As Mentos hit soda, bubbles form all over the surface of the candy. And, the fact that the Mentos candies sink to the bottom of the bottle gives a double-whammy. When all this gas is released, it literally pushes all the liquid up and out of the bottle in an incredible soda blast."

Mentos makes a geyser shaking it just make it fizz over the top but if you take diet coke and two mentos put in the mentos then the top really quick and shake it up and throw it on the street (far away from you) you will be pretty satisfied.
