How to Make Your Own Geyser with Diet Coke and Mentos Candy

Here's a fun way to teach your kids about chemical reactions, the power of pressure and geysers all in one fun experiment. All you need are a few items that your can find in most stores or online. Your kids will think it is the coolest thing ever.

(See link below for a a video of the Geyser Tube in action!)

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• 2 Liter bottle of Diet Coke
• A package of Mentos mint candy
• A Geyser Tube (optional, but far more entertaining)

1. Find an open outdoor area (preferably one that can be soaked in diet cola and not cause any problems) and set up your Diet Coke 2 liter bottle. You may want to to stabilize it using a terra cotta flower pot, or some other base that will prevent it from tipping over while the bottle's contents are shooting skyward.

2. 

   Attach your Geyser Tube (see link below) to the opened 2 liter bottle per the instructions included with the GeyserTube.

3. 

   Load the Geyser Tube with the Mentos candy. Make sure the pin has been inserted into the shaft of the tube first, or else you're gonna get wet!

4. When all observers are ready, pull the pin from the Geyser Tube to drop the Mentos candy into the soda.

5. 

   Within a second or two, a chemical reaction will occur causing the soda to shoot out from the bottle and spray many feet into the air! Repeat as often as you wish. Enjoy!

Tips & Warnings

• Stand back and don't point the geyser at observers faces.
• This is a great experiment for a homeschool family!
• You may waste alot of money doing this. Restrain yourself!
• Don't do this indoors. You'll not be happy with yourself afterwards.
