Why does coke blow up?

Here is what Mythbusters has to say " In a 2006 episode of MythBusters, a popular television program on the Discovery Channel,[7] the MythBusters concluded that the caffeine, potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke and the gelatin and gum arabic ingredients of the Mentos all contribute to the jet effect.[8] In addition, the MythBusters theorized that the physical structure of the Mentos is the most significant cause of the eruption due to nucleation. When flavored Mentos with a smooth waxy coating were tested in carbonated drink, the reaction occurs only mildly, whereas standard Mentos added to carbonated drink formed an energetic eruption, by their claim, affirming the nucleation-site theory. According to the MythBusters, the surface of the mint Mentos is littered with many small holes, allowing CO2 bubbles to form very rapidly and in great quantity, in turn causing the jet of foam. This was further supported when rock salt was used as an effective substitute for Mentos.[8] It is not an explosion but a rapid release of the carbon dioxide in the coke, diet coke works best.

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.[9][10]"

Why don't you try it and find out if it does.

Not a good idea to swallow Mentos http://www.youtube.com/watch?v=hKoB0MHVBvM

He said eat mentos... Not swallow whole.

Ok what will happen if I splatter coke on a flat surface and throw a mentos over it?and sorry I don't want to waste money hence I cannot try...

What 3 dollars or 4. The only way to find out is to experiment and do it on your own instead of getting others to answer questions for you that you need to figure out on your own.

Ok I will try it but isn't it risky?

Always better safe than sorry. I'd get a pair of safety goggles like those ones they used to make us wear in science classes when we had the chemicals and stuff out.. My cousin got me a cheap pair at the hardwood store. I think they were just a few dollars

Lol...I was thinking about filling a can with coke throwing mentos in it from above and videotapeing it ill...hmm guess you are rit my friend has I pair of swimming goggles they will do fine I guess
