Download Article

Dropping Mentos into a bottle of diet soda causes a physical reaction: as they fall through the soda, the Mentos candies break the bonds between the carbon dioxide and water (the combination that makes soda fizzy), releasing the carbon dioxide gas upwardly and out of the bottle.^[1] Past endmost the chapeau or lightly pushing a cork into the neck after adding Mentos to a canteen of nutrition soda, you trap that gas, creating pressure. When the bottle falls difficult confronting the basis, the cap flies off and the pressure releases, launching the canteen up into the air.

1
Buy i 2-liter bottle of Diet Coke. For the purposes of this instance, we're using Diet Coke, just you can actually use any type of diet soda (as long as information technology contains aspartame).
- Warm soda causes meliorate explosions, so avoid using cold/refrigerated soda.^[two] For all-time results, purchase room-temperature soda and so let it sit outside in the lord's day or in a pot full of hot (non boiling) water for a few hours before using it.
2
Buy 1 package of Mentos. Experiments have shown that while the original Mint Mentos will requite you a longer explosion, Mentos Fruit volition give you lot slightly shorter merely more than intense explosion. Other experiments have shown that Mint Mentos are the ameliorate choice because the gum arabic plant in the mint coating reduces surface tension and quickens the carbon dioxide's escape from the bottle, making for a more intense explosion.^[3]
- As the rocket is more than of a fast-acting matter, you might want to go for Mint Mentos.
- If y'all have the time and money to practise so, why not endeavour ane bottle with Mint Mentos and one with Fruit Mentos, and then compare the results?

5
Discover a wide-open space to build the rocket in. Your rocket is likely to bounce around like crazy; make sure it has plenty room to do that. If you're in a parking lot, make certain there are no cars nearby for at least a 50-human foot radius, if not more.

Remove 5 to 7 Mentos from the ringlet. The more Mentos you use, the better the explosion; notwithstanding, y'all don't desire to the Mentos to dip too far into the Diet Coke otherwise the explosion may begin before you lot can spiral the chapeau on the canteen.
4

Lay the Mentos on to one of the 4-inch (x.2-centimeter) strips of tape. They should await just as they did when they were notwithstanding in their original packaging: stacked on meridian of one some other like a roll of coins.
5

Place the other 4-inch (ten.2-centimeter) strip of record on height of the Mentos. Be sure to leave the sides of the Mentos exposed.
6

Cut a three-inch (7.62-centimeter) strip of masking record and roll it around your finger, glutinous side out. You lot'll use this slice to attach the Mentos to the bottle cap, so ensure that it's small enough to fit inside the cap.
seven

Attach the rolled tape to the top of the Mentos. Take the 3-inch strip of sticky rolled tape that you've but created and attach it to the top of the taped ringlet of Mentos. This volition create a "loaded" Mentos cartridge that you tin place inside the Diet Coke bottle.
8
Spike the Mentos cartridge into the bottom of the Nutrition Coke cap. Put the cap on a apartment surface, with its within facing upwards. Place the Mentos cartridge, viscid-tape side upward, into the soda cap and press downwardly to fasten it at that place.
- Exist careful non to press also difficult, every bit y'all don't want any Mentos falling out of the cartridge!

1
Twist the "loaded" cap on to the Nutrition Coke bottle. The cap should be securely on the bottle, simply not closed too tightly. If it'south closed also tightly, the cap might non come off when y'all throw the bottle, and the rocket won't work. As you twist the cap on, you'll also want to make sure that the Mentos do not touch the Nutrition Coke yet.
- If information technology seems like the Mentos will bear on the Diet Coke, you lot can either dump a small amount of Nutrition Coke out before screwing the cap on; redo your Mentos cartridge to contain fewer Mentos; or yous can effort your luck and spiral the cap on as rapidly every bit possible.
ii

Shake the canteen. Shake it so that the Mentos fall into the Diet Coke, and and so keep shaking. Practise this for at least a few seconds.

This is the best method if you're worried most getting hit by the rocket, as you can throw it far away from you and even run in the reverse direction.
- Another method is to throw the bottle at a side angle so that when it hits the ground, the ground knocks off its cap.
- Even so another method is to throw the bottle at more than of a 90-degree angle, cap-first, on to the ground.

Try again. You tin skip this stride if your rocket works right away. If the rocket doesn't go off when y'all throw it, selection it up and try unscrewing the cap a little before throwing it again. Just be careful not to unscrew the cap as well far, otherwise you're likely to cease upward covered in Diet Coke.
five
Enjoy the bear witness. When the bottle hits the ground, its cap should wing off and the Nutrition Coke-Mentos solution volition shoot out of the bottle's opening. This should cause the bottle to fly high up into the air. Depending on how you throw it, the bottle might as well bounce effectually sporadically for several seconds.
- Side-angle launches generally seem to cause the bottle to bounciness low and skid along the footing.
- Vertical launches (in which you lot throw the canteen directly up into the air and let it autumn to the ground) tend to give the rocket more than acme equally information technology shoots upward.
- If the canteen is still full of Diet Coke and Mentos just information technology's stopped moving on the ground, you tin can try to launch it again to see if information technology has any more flight left in it.
6

Make clean up after yourself. Once you've finished your experiment, don't forget to selection up after yourself. Clean upwardly any bits of tape or Mentos packaging that might have dropped to the ground equally you built your rocket. And pick up the rocket! Make clean out the bottle and put information technology in the recycling bin (or bring it to the bottle depot).

3
Make a larger rocket. Fill an Empty 4-liter milk jug with 4 liters (2 two-liter bottles) of Diet Coke. Leave enough room at the acme to add at least an 8-Mento cartridge.
- As with the original rocket recipe, stick the Mentos cartridge to the lid of the milk jug, fasten the hat, shake the container to release the Mentos into the Diet Coke, and then throw the jug high up into the air and let information technology hitting the pavement hard.

Go far a contest. Go together with your friends and each make your own rocket. Gear up a flag or some other way of measuring height, and have a judge watch and name the winner.
