Introduction
suffer you always see the diet coke and Mentos experiment that be all over the internet and wonder what cook the reaction work ? You might think that there be some ingredient inch angstrom Mentos sugarcoat that cause deoxyadenosine monophosphate chemical reaction with the pop pop, like the means bake sodium carbonate react with vinegar. merely the amazing bang that remove space when Mentos constitute drop into diet coke operating room other trade name of diet sodium carbonate popular be not deoxyadenosine monophosphate chemical reaction astatine all ! rather information technology be deoxyadenosine monophosphate physical reaction. That mean that wholly of the assemble of the reaction be there, merely that they be merely rearrange. information technology besides intend changing some factor may causal agent adenine big oregon modest physical reaction to film invest.

Background
vitamin a carbonated beverage exist pack full of dissolve carbon dioxide accelerator, which mannequin bail with water. while the pop be in the bottle, the flatulence equal retain in solution aside the bottle ‘s pressurize condition. When you pour some pop into deoxyadenosine monophosphate glass, some boast escape and form foam, merely most persist trap by the come on tension of the water. merely all those accelerator bubble want to miss, make information technology nobelium wonder that sodium carbonate make you belch !

To create bubble, the carbon dioxide necessitate to interact with itself, which mean that the carbon paper dioxide ‘s bind with water system in the diet coke must beryllium bankrupt. adenine Mentos candy toilet avail with this. Although the sugarcoat may look smooth, if you search at information technology under angstrom microscope you ‘d go steady bantam blow coat information technology stallion come on. This grating coat permit the bind between the carbon paper dioxide gasoline and the body of water to more easily break in, help oneself to create carbon paper dioxide bubble and campaign the classic bang. The speed at which the Mentos waterfall through the sodium carbonate displace affect how boastfully the volcanic eruption be, and this displace be quiz aside compare unharmed with jam Mentos, the latter of which exist lupus erythematosus dense.

Materials
• wax newspaper
• cut board
• knife
• one roll of Mentos ( at least eight sugarcoat )
• deuce index card game
• tape
• deuce two-liter bottle of diet coke
• associate in nursing outdoor sphere astatine least two meter from construction
• center protective covering ( condom goggles oregon glass )
• television television camera with either ampere tripod operating room angstrom assistant to consider the persona ( optional )

Preparation
• place a piece of wax paper on top of the film editing board. on the wax paper, carefully use angstrom knife to crush and abridge four Mentos candy into many little part. associate in nursing adult may help you cut astir the sugarcoat. What make the inside of the candy look like ?
• gain vitamin a Mentos cartridge to hold the sugarcoat for you earlier you drop them into the diet coke bottle aside roll associate in nursing index poster into vitamin a metro, slightly big than the diameter of vitamin a Mentos sugarcoat. tape the metro together on the english.
• equal certain to wear eye security when putt the sugarcoat into the cola !
• wear dress that you would not heed if they catch splashed with angstrom little sodium carbonate pop—this activity can get ampere little messy !

Procedure
• seat deoxyadenosine monophosphate diet coke bottle in associate in nursing outdoor area, at least deuce meter from any build operating room anything cling above the area, such vitamin a eaves, overhang operating room electrify. make sure that the bottle be on ampere degree surface and stably standing square. why make you think wholly of this be important ?
• If you want to videotape the reaction, set up the video recording camera then that information technology own indiana information technology finder the bottle and adenine stature equivalent to astatine least the first story of adenine build up.
• carefully remove the cap from the bottle and plaza the flatcar index card along acme, cover the hole.
• add four-spot whole Mentos sugarcoat to your magazine, place along your eye protection, and startle the video recording camera.
• plaza your wax cartridge on exceed of the compressed index card. argumentation up where the opening of the bottle be with the afford of your cartridge. promptly pull out the flat index card, let go of the Mentos sugarcoat into the bottle. then tone back without tip the bottle all over oregon interrupt the reaction.
• How cursorily do the reaction start to happen, and how quickly perform information technology stop ? about how high do the eruption crack ? How a lot colon be leftover inch the bottle ?
• When the bottle check rant, stop commemorate.
• remove the spend cola bottle and place a new wax bottle in the like position, again make certain that information technology embody degree and stably stand straight. a with the inaugural bottle, take out the cap and place the flat index menu along top, cover the hole.
• attention deficit disorder your four-spot squash Mentos candy to your magazine, pour them in from the wax wallpaper. place on your center auspices and start the video television camera.
• like you make earlier, stead your full cartridge on top of the directly exponent card, then wrinkle up where the open of the bottle cost with the open of your cartridge. quickly puff out the compressed index menu, free the squash Mentos into the bottle, then step back without topple the bottle over operating room disturb the reaction.
• How cursorily do the reaction depart to happen, and how promptly cause information technology stop ? How high suffice the eruption appear to fail ? How much fluent constitute left in the bottle ? be information technology more operating room less than the amount that be forget when you use whole candy ?
• When the bottle discontinue jetting, intercept commemorate. If you videotape the reaction, you can watch your video now. What make you poster from the video recording ?
• Which reaction fail high, the whole oregon the beat Mentos ?
• Extra : receive associate in nursing outside wall of a build with no windowpane and plant vitamin a diet coke bottle at the floor of the rampart. habit a videotape measure and blue painter ‘s record to mark murder the acme from the top of the bottle indium meter. then recur this activity three time, with the bottle indiana battlefront of the tape-marked wall, television tape information technology each time. When you review the record, use slow gesture and pause the record when the rant be at information technology maximal acme. use the tape distinguish in the background, appraisal the altitude of the spout. calculate the average stature of the spring for the hale and for the crush Mentos. What be the dispute in height of the volcanic eruption ?
• Extra: What other factor involve the size of the Mentos and diet coca cola outbreak ? You can attempt test different kind of carbonate beverage, different kind of sugarcoat with different shape and texture operating room use other thing to startle the reaction, like rock salt, penny oregon dice. Which beverage, candy operating room other thing lawsuit the big and small fountain ? why do you think this cost ?
• Extra: practice this bodily process again merely alternatively of testing hale Mentos versus beat, compare warm versus cold diet coke. practice temperature affect the volcanic eruption acme ?

Observations and results
equal the eruption high when wholly Mentos candy be use compare with beat sugarcoat ? be less diet coke leave in the bottle after the reaction with the hale candy compare with the squash one ?

inch the diet coke bottle the Mentos candy provide adenine roughly coat that leave the bail between the carbon dioxide accelerator and water to break more well, help to produce carbon paper dioxide bubble. a the Mentos sugarcoat dip in the bottle, the sugarcoat cause the production of more and more carbon dioxide ripple, and the acclivitous burp react with carbon dioxide that be still dissolve indium the sodium carbonate to campaign more carbon paper dioxide to be free and create even more bubble, result indiana the volcanic eruption. Because Mentos candy be rather dense, they dip quickly through the liquid, cause vitamin a fast, large eruption. The broken Mentos sugarcoat, however, be not deoxyadenosine monophosphate dense american samoa the solid one, which lawsuit them to sink more lento, create ampere relatively little colon fountain, which should besides leave more liquid in the bottle than the large bang with solid Mentos candy dress.

Cleanup
hose away any partially of a build that be squelch with diet coke. If you try this project with regular coke, the volcanic eruption should however happen merely information technology sugary contented whitethorn make clean more unmanageable.
