How to Make a Quick Soda Fountain

Diet Coke geyser

Creating a soda fountain is a quick project that guarantees great results with little effort. These soda geysers have been known to shoot up to 20 feet in the air. You may get soaked and the area around the fountain certainly will, so make sure you do this experiment somewhere outdoors where you can make a mess. Gather an audience and with a few dollars worth of supplies, you'll be the life of the party.

Things You'll Need

• 2-liter bottle of soda
• Mentos
• Piece of paper

Instructions

1. Open a fresh 2-liter bottle of soda. Diet soda is less sticky than regular and tends to work better. Tonic water can also be used. The carbonation is really all that is important.

2. Open the roll of Mentos and remove them all from the package.

3. Roll a piece of paper into a cone shape to use as a funnel. The Mentos all need to hit the soda at the same time.

4. Put the small end of your paper funnel into the top of the soda bottle and drop the Mentos into the funnel all at once.

5. Step back as fast as you can. The reaction will be immediate. In all likelihood, you will get wet so you may want to wear a poncho.

Tips & Warnings

• Do this experiment at night with tonic water and shine a black light on it for a glowing fountain.
