What Happens When You Eat Mentos and Coke? Reddit’s Explosive Experiment

Coke and Mentos have become synonymous with explosive eruptions, thanks to countless online videos showcasing the duo’s thrilling reaction. But what exactly is behind this scientific spectacle, and are the rumors of its dangerous consequences true? Join us as we dive into the science and safety behind the Mentos and Coke experiment.

The Eruption: A Tale of Bubbles and Pressure

Drop a few Mentos candies into a bottle of Coke, and within seconds, you’ll witness a powerful eruption of foam. This explosive reaction is triggered by the candy’s rough surface, which acts as a nucleation site for carbon dioxide (CO2) bubbles. As CO2 rapidly escapes from the liquid, it forms bubbles that quickly expand and rise to the surface, creating the characteristic eruption.

The Science Behind the Eruption

Nucleation: The Catalyst for Gas Release

Mentos candies have a unique surface structure that contains numerous microscopic pits and crevices. When dropped into Coke, these imperfections become nucleation sites for dissolved CO2 bubbles. Nucleation provides a starting point for bubble formation, allowing CO2 to escape from the liquid and collect into bubbles.

Supersaturation: An Unstable Equilibrium

Coke contains a high concentration of dissolved CO2, creating a supersaturated solution. Supersaturation refers to a liquid that contains more dissolved gas than it can normally hold at equilibrium. The presence of Mentos lowers the surface tension of Coke, making it easier for CO2 bubbles to form and release from the liquid.

Chain Reaction: A Cascade of Bubble Growth

Once CO2 bubbles begin to form around the Mentos candies, they create a chain reaction. As bubbles rise to the surface, they collide with other bubbles, causing them to merge and grow larger. This cycle continues, leading to the rapid formation of a large foam column that erupts from the bottle.

The Role of Surface Tension

Surface tension is the force that holds liquid molecules together. Mentos candies reduce the surface tension of Coke by adsorbing onto its surface. This reduction in surface tension makes it easier for CO2 bubbles to break away from the liquid and rise to the surface, contributing to the explosive eruption.

Safety Considerations

While the Mentos and Coke experiment can be a fun and exciting demonstration, there are some safety concerns to keep in mind:

  • Eye Protection: Avoid getting Coke or foam in your eyes, as it can cause irritation. Wear safety glasses or goggles for protection.
  • Clothing Protection: Wear old or disposable clothing that you don’t mind getting covered in Coke and foam.
  • Avoid Drinking the Foam: The foam produced by the eruption contains high levels of dissolved CO2 and can cause stomach upset or indigestion if ingested.
  • Cleanup: Dispose of the Coke and foam properly, as it can be slippery and potentially harmful to animals if ingested.

Tips and Expert Advice

  • Use Diet Coke: Diet Coke contains less sugar than regular Coke, reducing the risk of sticky residue and cleanup.
  • Refrigerate the Coke: Chilling the Coke before the experiment will reduce the amount of foam produced.
  • Drop Mentos Directly Into the Bottle: Don’t shake the Coke beforehand, as this can reduce the supersaturation and prevent a powerful eruption.
  • Use Multiple Mentos: More Mentos will create more nucleation sites and produce a larger eruption.
  • Experiment with Different Flavors: Try the experiment with different flavors of Coke, such as Cherry Coke or Vanilla Coke, to observe any variations in the eruption.

Frequently Asked Questions

  • Q: Can the Mentos and Coke reaction damage your stomach if ingested?

  • A: Yes, ingesting the foam can cause stomach upset and indigestion due to the high levels of dissolved CO2.

  • Q: Is it safe to pour Mentos and Coke down a drain?

  • A: No, the eruption can clog drains and cause plumbing issues. Dispose of the Coke and foam properly in a garbage can.

  • Q: Why doesn’t the eruption happen with other types of candy?

  • A: Other candies typically have a smoother surface, lacking the nucleation sites necessary for rapid CO2 bubble formation.

Conclusion

The Mentos and Coke experiment is a thrilling demonstration of the power of nucleation and supersaturation. While the eruption can be exciting to witness, it’s important to remember the safety considerations and handle the experiment responsibly. Whether you’re a curious science enthusiast or just looking for a fun and memorable experience, the Mentos and Coke reaction is a scientific phenomenon that continues to captivate audiences.
