It is likely that the experiment evolved over time, with different scientists and educators contributing to its development. The basic principles behind the experiment are:
* The decomposition of hydrogen peroxide: This is the core reaction that creates the foam.
* Catalysis by yeast or potassium iodide: These substances speed up the decomposition process.
The experiment's name "elephant toothpaste" likely came from the resemblance of the foamy eruption to toothpaste squeezed out of a giant tube.
In conclusion, there's no single person credited with discovering elephant toothpaste. It's a fun and educational demonstration that has likely been adapted and shared by many individuals over the years.
