Safety First
First and most importantly:

BE CAREFUL, DON'T LET YOUNG CHILDREN TRY THIS UNSUPERVISED, AND WEAR EYE PROTECTION.

We love the look of the goggles we wear in the videos, but we actually wear them to protect our eyes as well. You should too. You can get a pair of shop goggles for a couple of bucks at any hardware store. Pick a couple pair up when you're out buying your soda and use them. Besides, they make you look cool.

How to Make Your Own Coke & Mentos Geysers
The quick & easy way to make geysers is described below. It’s super simple and fun.

The advanced way requires some power tools and shows you how to make taller geysers. You can download the free advanced how-to PDF here.

The professional way uses our Coke & Mentos Geyser Kits. These are the nozzles we use in our live shows, and you can get the kit with six nozzles at our store. They allow you to create several different effects.

But for the fastest way to go out and make a geyser right now, read on…

The Quick and Easy Way to Make Your Own Geysers
What You Need

• a roll of mint Mentos (6 Mentos per geyser is enough)

• a piece of paper

• a playing card or a business card

a pair of goggles (lab coats are optional, but of course, stylish)

• a bottle of Coke Zero or Diet Coke (2-liter bottles are great)

Tip: Make sure the soda is at room temperature.

Here’s How You Can Do It
1. Go outside where you can make a big mess.

2. Open the bottle of Coke and place it on the ground.

3. Put on your goggles. Be safe and look cool!

4. Roll the paper into a tube so that the Mentos will just fit inside.

5. Hold the tube of paper upright and put the card over the bottom of the tube.

6. Load 4-6 Mentos into the tube, holding the card so they don’t fall out.

7. Carefully hold the tube and card directly on top of the bottle, lining up the tube and the mouth of the bottle.

8. Pull the card out from under the tube, letting the Mentos drop into the bottle.

9. Get out of the way.

10. Celebrate!

More Experiments
If you have a curious mind, try testing different sodas and different candies. What happens when you drop a small stack of coins into a bottle of Sprite? What happens when you use a bottle of soda from the fridge instead of a bottle at room temperature? Experiment to find out!

    you guys are amazing, you have awesome goggles and sweet lab coats [ very stylish indeed ] you get to do experimants and have crazy fun at the same time it’s insane and i love your amazing video’s i used your tips and some friends and i put on out goggles and lab coats and let the guysers begin!! you guys are a sensation and just awesome!! thanks for the awesome tips big fan!

  • babe ruth

    that is amazing im going to try soon hope it works

    I had to watch one of these videos for homework, but it’s amazing how you can actually acquire that many mentos and bottles of diet coke without getting stares. It’s also amazing that they dedicated a website solely to using household materials in cool science experiments. Eepybird rocks!

    this is the the the the the beeeeeesssssstt shizam

    mentos and coke is cool experiment weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee bam

  • Jennifer

    This is going to help me sooo much with my science project . But , is there any other suggestions you might have to make our own geysers at home to be able to do multiple explosions at a time ?? Not just one , but more at the same time ??

    the brasil S2 YOU

    that was aswome

    that is cool

  • Darby

    i think your awsome keep it up!!!!!!!!!!!!!!!!!!!!!!!!!!

  • DARBY SADLER

    I LOVE YOUR EXPERIMENTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Catalyst

    I’m a student in South Korea and my school chemistry club
    is planning to perform this experiment at school festival after seeing your experiment video.
    actually we’re quite worried about planning the detail, but your PDF file helped a lot!!! thanks! you’re our lifesaver!!
    to make the experiment much more impressive, I think we need to make some nozzles (sorry, South Korea is too far away to purchase your kits). so, can you send us some advice to my Email?(if you have time ^_^ )

    oooh,

    I got it!!!

  • http://yahoo happy

    thx 4 showing me how!!!!!!!!

  • karina rocha

    can i do this with a sparkling water can and one mento? how so i can make it go high?

  • Patty

    We failed :(

  • http://nutz4christ.weebly.com AlwaysBored

    thank you this helped a lot. i used it for a science project and got a really good grade! awesome :D
    P.S. do you guys know of any other substances you can combine to make things explode besides vinegar and baking soda?

  • peari

    This helped me so much with my science class, and oh my god I love this site.

  • :))))))

    this is soooo awesome

    i love this!!

  • joey

    this is not really how it goes thats a fony lie first yu must:

    1. open the bottle and insert the geyser tube

    2.put at least 6 mentos in the bottle

    3.run or back away at least 5 or 3 ft. away from it

    4. enjoy the beautiful sight

    5. clean up all the mess and your finish

  • Joshuanlee

    its acualy 7 mentos

  • alexander guerra

    no it is still “6 MENTOS”

  • Ms. Sarah

    this is really going to help me with a new project idea for my class. Keep it up.

  • Tianadockery

    I thought their waz a video to this! huh?

  • Mido

    Why cant u just open the mentos from both sides and put the whole thing eith the psper in the bottle

  • Jeff Bigler

    I’m a high school physics teacher in Lynn, MA. This year’s final exam was for the class to split into lab groups. Each group made a Diet Coke & Mentos fountain using different size holes in the cap. (Each group used a fresh 2L bottle of Diet Coke and 5 Mentos.)

    Each group measured the height of their fountain’s spray and calculated the pressure that caused it (density x acceleration due to gravity x height). Students individually graphed pressure vs. diameter of the opening and extrapolated the graph to find the pressure that would theoretically be created in a 2L bottle of Diet Coke with 5 Mentos and no hole in the cap.

    One class got decent data, and found the pressure with no opening to be around 95,000 Pa above atmospheric pressure.

    I wrote the experiment up on my blog, at http://www.mrbigler.com/blog/2012/05/26/diet-coke-mentos-final-exam-physics-version/

    thanks for all the useful tips!
    we are doing this experiment with different sodas for science
    thankyou for making boring science lessons into awesomeness!!!
