Protected by fear, couple of kids actually finish up attempting the stunt, also to prove your guts to your peers.

You are watching: What happens if you drink coke and eat mentos

After all, it’s famous that dropping Mentos into a bottle of Diet Coke will reason a suddenly geyser that soda foam to erupt.

So what wake up if you drink coke and eat Mentos?

You’ll suddenly endure an upsurge of soda foam and also will likely burp or vomit up big amounts of the stuff in seconds.

The suddenly swell the carbon dioxide inside your stomach will require an escape.

This is the exact same thing the happens to any type of other container through volatile ingredients.

Thankfully, there’s already a popular escape hatch situated at her mouth.

Swigging some Coke and swallowing part Mentos will essentially cause a many the carbon dioxide trapped in the soda in her stomach to all of sudden bubble and shot to escape.

However, her stomach is not enough of a seal to keep this sudden pressure adjust contained inside.

If this to be the case, eat Mentos and drinking soda may without doubt be dangerous.

But as it stands, all you’ll suffer if girlfriend drink Coke and eat Mentos is some mild discomfort and also possibly some embarrassing vomiting.

While over there are numerous stories of civilization dying from suddenly exploding as result of the sirloin of carbon dioxide widening in their stomach, no one of these stories space factually true and no video footage has ever before been recorded of together an accident.

It is likely that these stories room exaggerated and have been spread out on the web for entertainment purposes.

Coca-Cola is a carbonated beverage the is full of dissolved carbon dioxide.

The gas form of carbon dioxide bonds through the water molecules existing in the cola. Many Coca-Cola is preserved carbonated by a sealed bottle, which create a pressurized environment where the carbonated gas can’t escape until the cap has been broken off or opened.

This is why soda progressively loses that is carbonation in time after it’s to be opened.

When soda is poured right into a glass, many of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface ar tension.

While several of the gas does manage to escape by forming bubbles, most of that does not.

The rest of the procedure happens many thanks to the physical properties the Mentos.

In bespeak for much more carbon dioxide balloon to it is in created, the bonds through the approximately water in the soda have to be broken.

Mentos has actually thousands that tiny bumps over that is surface even though the candy might look smooth to the nude eye.

The rough surface ar of the liquid creates friction whereby the more heavier carbon dioxide molecules can sink and also break far from your bonds v the water surrounding the. The carbon dioxide, once freed from its bonds, forms tiny bubbles that room lighter than water and which want to rise.

Imagine this small procedure happening hundreds of times in the 2nd and you acquire the trademark fractional of soda bubbles that climb out of the bottle.

This impact can be maximized come a specific extent by adding a couple of Mentos candies come a offered soda bottle, although over there is a breaking allude where adding much more candies doesn’t do the geyser any much more impressive.

As previously stated, the surface ar of Mentos candies is what renders this reaction work.

All the the tiny pores on a Mentos’ surface break the polar bonds in between the carbon dioxide and also the water, i m sorry is why any Mentos candy with a smooth surface stops working to produce any reaction in ~ all.

Since the Mentos simply facilitates the development of bubbles, the liquid will continue to act together a catalyst because that carbon dioxide bubble formation until all of the surrounding CO2 has been worn down in the bottle.

This doesn’t always cause a geyser come erupt out of a coke bottle; for instance, a Mentos candy reduced into quarters will develop less that a reaction than a full candy.

But the process is consistent and grows exponentially.

If sufficient candies room thrown into a party of Coke, the geyser is created because all the bubbles straightforward pile atop one an additional on your journey out of the confined an are of the bottle.

Mentos’ ingredients also aid this reaction to some extent.

Mentos candies generally have gum Arabic and gelatin in their formulas.

Both of these ingredients lower the surface stress of the soda, i beg your pardon exacerbates the bubbling reaction and also makes the geyser happen much an ext quickly. Lower surface tension renders it less complicated for the balloon to break out to the surface and also attempt come escape.

Furthermore, dropping the Mentos right into the soda party with pressure to do it descend quickly will force much more carbon dioxide through its tiny pores and also make a quicker reaction were more bubbles are created in a short amount of time.

Mentos the drift peacefully with the soda will have a weaker reaction in comparison.

Theoretically speaking, any type of candy that has actually enough tiny pores favor Mentos should have the ability to do this job.

However, there space very couple of candies with the very same kind that porous surface as Mentos, i beg your pardon is why the scientific research experiment is generally done with these candies rather of others.

However, any type of carbonated soda can be a replacement for Coca-Cola; the an essential is carbonation much more than something else.

You might even theoretically attain this with club soda, although the surface tension of the water wouldn’t be weakened because club soda only has a couple of basic ingredients.

Diet soda stereotypically has a better reaction than regular soda.

This is because diet sodas have actually aspartame whereas continual soda typically does not.

Regular soda supplies sugar or corn syrup come derive most of that sweetening flavor, yet diet soda eschews this ingredients in the surname of under calories and better health.

While sugar and also corn syrup both aid to lower the surface anxiety of water to some degree, aspartame go this to a much higher quality and can do the geyser result happen much more quickly.

Therefore, diet soda is better than continual soda if you want to do the best Mentos foam geyser possible.

You can additionally increase the result by including extra ingredient to a given soda.

Adding some dishwasher soap and also water to a soda bottle deserve to lower the surface anxiety of the water even further.

The result splash native diet soda with this mixture would surely be something to record.

Finally, making her soda bottle warmer instead of colder will make the geyser greater and faster.

Gas becomes much much less soluble in warmer environments; cold soda stifles the gas development effect and will make her geyser weaker.

All of these tricks help to enhance the speed and drama that a Mentos eruption.

Any Mentos in the soda will certainly eventually reason all the carbon dioxide to become gaseous and escape the bottle; the only difference is in exactly how fast and also how explosively it occurs.

You have the right to see the outcomes of this yourself by crushing a Mentos and dropping it right into a bottle, climate comparing the reaction to the entirety candy v all its pores intact.

Are There any type of Long-Term Health threats Eating Mentos & Soda?

The irreversible health risks of drinking Coke and eating Mentos are mainly nonexistent.

Since the escaping gas either comes the end in the kind of a lengthy burp or in foam that’s expelled v vomiting, the concern basically stops as soon as the soda has evacuated your stomach in one method or another.

It definitely won’t it is in comfortable and also Mentos, yet there aren’t any kind of real health dangers from doing so.

The only way you might reliably damaged yourself indigenous this stunt is if you did that over and also over again.

Vomiting in overabundance is never ever a good sign since stomach acid wears far the cell of the esophagus and can cause mouth or throat cancer.

Occasional vomiting native sickness or a stomach an insect is normal, yet forcing yourself to litter up soda and candy at every party is a one-way ticket to extra complications.

Furthermore, upsetting your stomach needlessly by causing a roiling storm the bubbling coke is likely to do you feel poor in general, full stop.

Your stomach is surrounded by many other interior organs that transition normally once you eat a big meal.

But the bubbling you’ll feeling on her insides isn’t straightforward or gentle, so the shouldn’t it is in performed regularly.

Overall, there’s no require to concern if you’ve excellent this when or twice prior to on a dare from a friend.
