Does the Mentos Trick Work with Regular Coke?

Does It Have To Be Diet Soda?


Why diet soda for the Mentos and diet soda geyser? It's a lot less sticky!

Why diet soda for the Mentos and diet soda geyser? It's a lot less sticky! However, the trick works just fine with regular soda.

Have you ever wondered whether or not the Mentos trick works with regular Coke? Does it work with other drinks? Here's the answer!

The Mentos Trick

All you do is drop a tube of Mentos candies into a bottle of soda. The carbon dioxide in the soda comes out of solution very suddenly, shooting up into the sky and drenching anyone within range with soda. Usually, the trick is done using diet soda, especially Diet Coke or another cola, however, the main reason for this is because diet drinks are less sticky/easier to clean up than other sodas.

What Works and What Doesn't

  • Soda
    The trick works with any carbonated beverage. It's actually very cool when performed with tonic water under a black light because you get a glowing blue fountain. However, you can use seltzer water (very easy cleanup) or any soda. While you may get a slightly higher fountain from a diet drink compared with a sugary one, the real determining factor is the size and shape of the bottle. A 2-liter or 1-liter bottle works much better than a smaller bottle. Plastic bottles seem to produce a better effect than glass ones, but really, either works. Flat soda will not work.


  • Candy
    It doesn't matter what flavor of Mentos candy you use, but Mentos candies do seem to work better than similarly-shaped candies (e.g., M&Ms, Lifesavers). The other candies do produce a geyser, but it won't be as tall. Mentos stack neatly onto each other, leaving very little extra space, so they displace liquid better than other candies. The carnauba wax that coats the candies seems to be key in producing the effect, because old candies or ones that have been opened for a while won't produce a tall geyser.
