Why does Coke explode when you shake it?

It's the extreme pressure of the carbonation trying to force itself out of a small opening.  It's like when you hold your thumb over the end of a garden hose, it makes the spray harder because the pressure is backed up in the hose.  If you had a big enough opening, it wouldn't spew everywhere.

Be careful, it may explode!

I think the fact that soda is carbonated makes it fizz.

According to the following website, it depends on the form of cocaine being produced, and looks like some really nasty chemicals are involved (sulfuric acid, kerosene, benzene, ammonia, etc...). Yuck.\n\nhttp://en.wikipedia.org/wiki/Cocaine

A mentos has lots of pits in it you can't see.  Basically it looks like the surface of the moon under a microscope.  These pot holes allow the carbon dioxide to become displaced and bubble (I think this is called nucleation - spelling).  The ingredients on the diet coke make the foam and the carbon dioxide makes it fountain up about 6 feet in the air.  (Was walking back from doing the grocery shopping and saw these two store clerks doing the very same experiment with diet Pepsi - was very amusing.)  They also did this experiment on Mythbusters.

Sorry but only the first answer was close.  The air inside the baloon is compressed, because of its containmentt inside the stressed rubber.  (You need to blow to fill a baloon).  When the rubber is split, the air expands rapidly to equal the surrounding pressure.  This rapid expansion propogates outward, causing tha bang

Now thats a weird experiment. Firstly, most of the ingredients in Coke are Inert. But however, since it is carbonated, and has mild levels of disinfecting chemicals, it has a slightly acidic nature. Now when you drop nail filings (which are mostly calcium compunds) there is a chance that they react with the acidic solution. But the least that can happen is a soft neutralisation process and nothing else. So there is no chance that you will fall in coma when you drink such a mixture.

carbonated drinks [COKE] have co2 which  is the gas that cause the foam,bubbles when you pour it. I dont think it really burns but it gives you that sensation because when you BURRRRRP! {EXCUSE ME} the gas is rushing out escaping thru your nostril bring your inner body temperature to ambient tempeerature usally cooler that body temperature

The real answer is because James Bond orders his martinis shaken and not stirred in the movies.  It became a pop culture thing to order martinis this way even though they have no idea what the difference is.\n\nMartini purists have their martinis stirred since the stirring is supposed to blend the gin and the vermouth without "bruising" the gin.  That's pretty much been determined to be hogwash.  Gin doesn't really bruise.\n\nIt's just a matter of personal preference.  As a bartender, I always shake anyway and it's more to chill the gin anyway.  A proper martini is going to have very little vermouth in it at all.\n\nBartenders will secretly make fun of anyone who orders a martini "shaken not stirred." They have just confirmed the fact that they know nothing about martinis.

Because if the composition is too acidic or too basic one way or the other, the soda could be toxic.\n\nAlso, it wouldn't taste good or sell well.

Aaliyah's Mama  - answered part of the question and she is right\nwhen coca cola first came out it was use as a drug to treat eplipsic cause it contained the drug cocaine in it .  Then it became a house hold drink.  \nand for some time they did not know why a lot of people back then were buying it right and let and getting buzzed out of there heads   until a few years later they found traces of cocaine that gave it most of it'e taste  since then coca cola company replaced the drug with arifishal flavor but now it does not contain any of the drug cocaine any more   you might be getting a surgar buzz if anything.

One word answer: agitation\n\ncoke and other drinks are "areated" with carbon dioxide under pressure. carbon dioxide does not like stay dissolved in water and bubbles out, causing the fizz effect in sodas.\n\nnow for the carbon dioxide to bubble out, it needs energy. this energy can be supplied by :\n\n* heat : this is the reason why warm coke is less fizzier than cold coke. the carbon dioxide has already bubbled out\n\n* agitation : shaking a bottle of cola, supplies the carbon dioxide enough energy to fizz out. so does pouring coca cola over ice. if you put ice in coke though, you are doing it gently. you would see a lot of fizzing of you threw you ice in with a lot of force \n\nwhen you vend onto ice at mcdonalds, the cola touches ice straight away and has energy taken away from it and hence fizzes less.\n\nhope that clears things up for you :)

Pepsi is carbonated (contains bubbles of carbon dioxide).  This means that there is actually less volume of frozen liquid to be melted.

Easy. You heated the can, which means the air inside the can, including steam, was at a high temperature. That means it occupied more space. When you dunked it into cold water, the steam turned back into water, and the air in the can became more dense. The can crumpled because you basically created a vacuum effect. You decreased the volume suddenly by reducing the temperature.\n\nEnough?
