coca cola + mentos..GreAt!!

its good to drink coca cola when you are thirsty but don't ever think to drink it together with mentos ok! did you know that drinking coca cola together with mentos can cause death?? i think this is an interesting facts that i can share with all of you.
is scary right? i did not believe it too at first..but...we still have to believe it,..this is what i get from wikipedia.


Soda and Candy eruption (also known as a Coke and Mentos eruption or a geyser) is a reaction of carbonated beverage and Mentoscandies. The numerous small pores on the candy's surface catalyze the release of carbon dioxide (CO2) gas from the soda, resulting in the rapid expulsion of copious amounts of foam.
When the candies come into contact with the liquid, a reaction causes the formation of foam at a rapid rate. A 2006 episode of the television show Mythbusters concluded that the potassium benzoateaspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatinand gum arabic ingredients of the Mentos, all contribute to formation of the foam.[1] The structure of the Mentos is the most significant cause of the eruption due to nucleation. Mythbusters reported that when fruit-flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas mint-flavored Mentos (with no such coating) added to carbonated drink formed an energetic eruption, affirming the nucleation-site theory. According to Mythbusters, the surface of the mint Mentos is covered with many small holes that increase the surface area available for reaction (and thus the quantity of reagents exposed to each other at any given time), thereby allowing CO2 bubbles to form with a rapidity and in a quantity that are responsible for the "jet"- or "geyser"-like nature of the effusion.[2] This hypothesis gained further support when rock salt was used as a "jump start" to the reaction.
A paper by Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina goes into detail on the reasons and physics behind the reaction by stating that it was found that the rough surface also helps the explosion. Coffey found that the aspartame in diet soda lowers the surface tension and causes a bigger reaction, but that caffeine does not accelerate the reaction.

this happen shortly after you add mentos to 2L of coca cola..scary right?(^_^)
i also found some videos that i would like to share it with all of you..
so?? think wisely before you eat your food ok! 
that's it for today...(+_+)
