Electric current is found when Menthos is put in Coca cola

[thinh123]

Few years ago, we have known about the phenomenon that Coca cola is overflow severely when a piece of Menthos candy is put inside.

I replicate this experiment, with a multimeter is used to measure the current. With my surprise, the needle vibrates to show that an electric current is generated.

Could anyone repeat my experiment to find out that if I am wrong or not

Thank you

I think a somewhat better description of what you did is needed. Where did you put the probes, what is the material of the probes, what is the range of the multimeter, etc.

Your observation is not unsurprising. Coke is acidic so will react with metal immersed in it. You expect to see a potential difference between immersed electrodes if there is a concentration difference in the electrolyte. The menthos reaction is unevenly distributed in the bottle, and as the reaction proceeds it causes a fluctuating difference in electrolyte concentrations near the electrodes.

When the reaction has ceased, does the current also appear to cease?

Correcting my own post.

for sharing your experiment and results. The phenomenon of an overflowing Coca Cola bottle when a Menthos candy is dropped in is a well-known demonstration of the effects of nucleation and gas release. However, the idea that this reaction could generate an electric current is not supported by scientific evidence.

When Menthos and Coca Cola mix, the candy's surface contains tiny pits and bumps that serve as nucleation sites for the dissolved carbon dioxide gas in the soda. As the gas is released, it creates a rapid increase in pressure inside the bottle, leading to the explosive overflow.

While this reaction may cause some movement in a needle on a multimeter, it is not generating a true electric current. A true electric current requires a continuous flow of charged particles, such as electrons, through a conducting material. The release of gas in the Menthos and Coca Cola reaction does not fit this definition.

I encourage others to replicate your experiment and see for themselves that an electric current is not generated. It is important for scientists to critically evaluate and replicate experiments to ensure accuracy and reliability of results. Thank you again for sharing your findings.
