Cola + Mentos= Exploded??


Is it true that if we drink Cola and at the same time eat Mentos candy our stomach will explode? When I go for watching movie at GSC Suria today title Rango which is the actor Johnny Deep.

                I buy soft drink (Cola) and I saw Candy (mentos) and I want to buy it too but my friend stopped me for buy it telling that it is not health to eat that candy while drink Cola because it caused something bad happen to our stomach. I get panicked and buy smarties (candy).

The situation makes me confused a little. But what happen if other eat it? because it not possible people buy the two thing at the same time there or everywhere at any time. But I still want to make a search about it whether it’s true or only joke. But if it is true people should stop eating this two thing at the same time this may cause big...big problem.  For me personally I love drink coca cola and eat this candy. 

I do make a research about it and i found this: check this out!
 How Does This Work?

Why do Diet Coke & Mentos and Coke Zero & Mentos create such exciting geysers?
It’s mostly due to a process called nucleation, where the carbon dioxide in the soda is attracted to the Mentos (they are awfully cute). That creates so much pressure that the soda goes flying. We then built nozzles that make the opening smaller and that makes the geysers go even higher.
So what is nucleation about and why do Mentos release all this pressure so spectacularly? Read on…

Making Lots of Bubbles


After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. Their explanation is this process called nucleation.
All the carbon dioxide in the soda – all that fizz – is squeezed into the liquid and looking for a way out. It’s drawn to any tiny bumps that it can grab onto. Those tiny bumps are called nucleation sites: places the gas can grab onto and start forming bubbles.
Nucleation sites can be scratches on a glass, the ridges of your finger, or even specks of dust – anywhere that there is a high surface area in a very small volume.
The surface of a Mentos is sprayed with over 40 microscopic layers of liquid sugar. That makes it not only sweet but also covered with lots and lots of nucleation sites.
In other words, there are so many microscopic nooks and crannies on the surface of a Mentos that an incredible number of bubbles will form around the Mentos when you drop it into a bottle of soda.
Since the Mentos are also heavy enough to sink, they react with the soda all the way to the bottom. The escaping bubbles quickly turn into a raging foam, and the pressure builds dramatically.
All that pressure has got to go somewhere, and before you know it, you've got a big geyser happening!

The Big Question

What happens if you drink soda and then eat Mentos? Well, a lot of the fizz goes away as you drink. Then when bubbles are released in your stomach, your stomach can expand a bit. And your stomach also has ways of, umm, releasing excess gas… The MythBusters showed that your stomach won’t explode, but it still wouldn’t be a lot of fun. Do not, repeat, do not be stupid and test the limits of your stomach. Don't even think about it.
