How to Make a Mentos Diet Coke Fountain

Introduction

The urban legends are true. The makers of Mentos, a candy that is most identifiable for its ridiculous commercials, have another dubious feat to add to their product's already auspicious repertoire. For chemical reasons that we do not fully understand, adding Mentos to Diet Coke (and probably other carbonated beverages) produces volatile results. Just look at the video, then read the steps to replicate this simple household science experiment on your own.

Tips & Warnings:

Adjust the amount of soda and/or Mentos you use for varying explosiveness.
Try using a range of different receptacles with different sizes openings. For example, a smaller hole through which you drop the Mentos will lead to greater pressure and thusly a more powerful soda spray.
A funnel or makeshift loading device of some sort may help you with the act of dropping the candy in the cola.
Avoid flat or older soda due to law of diminishing returns
Don't aim the Diet Coke bottle at people's faces. That's just not cool.

Step1

Choose a wide open space to perform your little experiment, preferably outside.

Step2

Take the unopened bottle or can of Diet Coke and place it in this space. Keep the women and children at a safe distance. Prepare your Mentos for submersion.

Step3

Drop at least 3 or 4 Mentos into the soda. Drop the whole pack in if you're feeling especially courageous and don't want to eat any of the Mentos.

Step4

Get out of the way. Actually, run if you don't want to be saturated in Diet Coke, a fluid that is rumored to have the ability to disintegrate rust. We will cover that particular wive's tale in a future eHow.
