Get ready to be amazed as you combine these simple ingredients and watch the impressive eruption unfold before your eyes!

Eruption in Action

Now's the time to release the power of the Mentos geyser! Head outside with your bottle of diet cola and pack of Mentos. Remove the bottle cap and quickly drop about half the pack of Mentos into the bottle. Rapidly step back and watch as the soda shoots out of the bottle like a geyser, reaching impressive heights!

The science behind this reaction lies in the Mentos' composition and surface. Mentos candies are covered in tiny pits that dramatically increase the surface area for bubbles to form and rapidly expand.

Additionally, the gum arabic and gelatin in Mentos further reduce the surface tension of the liquid, making it easier for bubbles to form. When you drop the Mentos into the cola, the candy disrupts the bonds between the CO2 gas and water, causing a rapid release of carbon dioxide bubbles.

This sudden increase in pressure propels the soda out of the bottle in a spectacular geyser-like eruption. Experiment with different types of soda and varying amounts of Mentos to discover which combination creates the most impressive geyser!
