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

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

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,,,,

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

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!
May 21st, 2008 at 6:16 pm
does this really work?
May 24th, 2008 at 6:57 pm
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?
