How To Make a Mentos Coke Rocket

Want to make your own carbonated gas rocket? You’ve probably already seen someone make a Mentos Coke Geyser. Just drop a few Mentos into a bottle of Diet Coke and you’ll see a violent 16 foot fountain of Coke explode out of the bottle. Although that may sound somewhat exciting, the geyser is the boring “science teacher” version of this experiment. If you really want to unleash the carbon dioxide power in a 2-liter bottle of Diet Coke, try making a Mentos Coke Rocket. Here’s how:

  1. Buy a 2 litter bottle of Diet Coke and a roll of Mentos. You can use any soda but room temperature Diet Coke for some reason is the best performer.

  2. Find a big open area to launch your Mentos Coke Rocket. Don’t do it indoors. Trust me.
  3. Slide the paper cover off the Mentos (leave the foil wrapper on) and slip the roll into the bottle.
  4. Quickly cap the bottle and shake it.
  5. Gently unscrew the cap, just a little, until you start to hear fizzing.
  6. Throw it down and cover your face!

  2. omg r u sure this really works cause i dont want to make a fool out of my self doing it infront of my class

  3. WEll, if your scared about the in your face thing, then throw it way up in the air behind you, thats been proven to work too

  4. i couldn’t find any rolls of mentos anywhere so i just bought a bunch off yahoo. the first time i tried this, all the mentos shot out at my face when i was 10 feet away behind a fence. works well after a while if you keep trying

  5. do we have to put the cap back on after we open it alittle bit? its not working can you please tell sipmle instructions thanks.

  6. This experiment is a JOKE! We tried it with 6 diff 2 Ls exactly how this site explained as well as a few other ones incase this way was the wrong way to do it. EVERY time the stupid bottle just hit the ground and stayed there. Didnt explode or NOTHING. What a waste of my $15.00… the cap never came off never exploded nothing not rocket, and no coke came out aswell nothing… What am I doing wrong,,,,

  7. hey spencer not to be a jerk but dude it said unscrew the cap a lil

    i bought ten 2L’s still have 4 did 6 today only takes around 4 mints per bottle make sure you undo the lid a tad befor throwing it…. if it dont blow undo cap more and throw higher in air gravity and pressure should do the rest

  8. im doing this for my science fair in april! omg omg its so awsome. but my school is very small and it doesnt have a very big fieled (its not even a fiel;d) and there house all around so yaa ;’ kuleo

  9. whoa sweet, for my science experiments, im gonna strap a toy to it and see if it carries it away, i hope i get an A+ or sumthing

  10. Hey in my inpc class were doing an experimt with mentos coke and bottle rockets. Were trying to see if the size of the bottle matters and how high we can make it go. If you have any suggestings please tell me?

  11. i am doing this for a school project and i have a few questions.

    1.do you have to use a 2 liter bottle
    2. does it really wirk cause i dont want to embarass myself!

  12. I tried this about 10 times and all of the times when I threw it on the ground it just popped and exploded on the ground. It didnt even rocket.
    So yeah I was pretty dissappointed ( And wet ) and I wanted to know if I was throwing it too hard or light?
