Hydrogen peroxide is a chemical compound made up of two hydrogen atoms and two oxygen atoms. It is a pale blue liquid that is often used as a disinfectant or bleach, and it can be found in many household cleaning products.
One interesting experiment that can be done with hydrogen peroxide is the potato experiment. This experiment involves cutting a potato into thin slices and soaking them in a solution of hydrogen peroxide for a period of time.
To perform the experiment, you will need the following materials:
- A potato
- Hydrogen peroxide (3% concentration)
- A plastic container or bowl
- A knife or potato slicer
- A timer or clock
To begin, slice the potato into thin rounds using the knife or potato slicer. You can cut the slices as thin or as thick as you like, but thinner slices will likely react faster to the hydrogen peroxide solution.
Next, fill the plastic container or bowl with enough hydrogen peroxide to cover the potato slices. Carefully place the potato slices into the solution and set a timer for 10 minutes.
As the potato slices soak in the hydrogen peroxide, you will begin to notice some bubbling and foaming. This is due to the release of oxygen gas as the hydrogen peroxide decomposes. The oxygen gas is what causes the bubbling and foaming, as it becomes trapped in the potato slices.
After 10 minutes, remove the potato slices from the solution and place them on a plate or paper towel to dry. As the potato slices dry, the oxygen gas will escape, and the bubbling and foaming will stop.
You may notice that the potato slices have changed color after soaking in the hydrogen peroxide solution. This is due to the bleaching effect of the hydrogen peroxide, which can lighten the natural color of the potato slices.
Overall, the potato experiment is a simple and fun way to demonstrate the decomposition of hydrogen peroxide and the release of oxygen gas. It is a great way to introduce students to the concept of chemical reactions and the properties of hydrogen peroxide.

Starbucks' rate of expansion accelerated in the early 2000s: after opening about 1,200 new stores each year from 2001 to 2004, the company added nearly 1,700 new outlets in 2005, pushing the chain past the 10,000 unit mark.
