We Tried 4 Alternatives to Mentos in Cola… Which One Works Best?

Looking for a thrilling science experiment that doesn't require a trip to the store? This hands-on activity explores what happens when you swap Mentos for everyday household items in a bottle of cola. Kids get to predict, observe, and discover which alternatives create the most impressive reactions—making it a perfect blend of fun and learning about chemical reactions and gas release.

This experiment is ideal for backyard adventures, classroom science lessons, or rainy-day activities. Since reactions can be messy and exciting, you'll want to set up outdoors in an open space with materials you probably already have at home. Watching each test unfold teaches children that great scientific discoveries don't always require special supplies—sometimes the best learning comes from curiosity, creativity, and trying something new.
