Mentos and Soda Project

By Anne Marie Helmenstine, Ph.D., About.com Guide

This is a super-easy project that is safe and fun for kids. All you need are a roll of Mentos™ candies and a 2-liter bottle of soda. Diet cola seems to work best, but really any soda will work. One advantage of using diet soda is the end-result won't be sticky.

Mentos & Soda Materials

• roll of Mentos™ candies (any flavor)
• 2-liter bottle of soda (diet soda is less sticky; diet cola seems to produce the best fountain)
• index card or sheet of paper

Prepare for the Project

1. This science project results in a jet of soda up to 20-feet in the air, so it's best if you set up outdoors.
2. Roll a piece of cardboard or paper into a tube. Drop the roll of candies into this tube. In this photo, we used a sheet cardboard from the back of an old notebook. Use your finger to keep the candies from falling out.
3. Open the bottle of soda and get ready...
