Which will last longer vineger with baking sida and dishwashing liqued or a 2 liter coke whole thing of mentos?

This is a fun thought experiment! Here's a breakdown of why the vinegar and baking soda mixture is likely to last longer than the Coke and Mentos combo:

* Vinegar and Baking Soda:

* Chemical Reaction: The reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) produces carbon dioxide gas, which creates the fizzing effect.

* Limited Reactants: Once the vinegar and baking soda are fully reacted, the reaction stops.

* Long-Term Stability: The leftover solution (likely mostly water) is relatively stable and won't undergo any significant further reactions.

* Coke and Mentos:

* Rapid Reaction: The Mentos trigger the rapid release of dissolved carbon dioxide from the Coke, causing a massive geyser.

* Short-Lived: The reaction is quick and dramatic, but the fizz doesn't last.

* No Lasting Solution: Once the carbon dioxide is released, there isn't much left in the Coke besides sugary, carbonated water.

In Conclusion:

The vinegar and baking soda mixture, although it may not be as visually exciting, will last much longer because the reaction is complete and the remaining solution is stable. The Coke and Mentos reaction, while spectacular, is a short-lived burst of fizz.
