How to simulate acid rain
Gather the necessary materials.
This experiment simulates the emission of harmful gases into the environment that combine with water in the sky to lower the ph and cause acid rain. To perform this simulation, you will need an eyedropper, distilled water, a glass jar with a lid, bromothymol blue, a small clear container, and sulfur-based matches.
Choose safety matches, which contain more sulfur and less phosphorus than other types. Adult supervision is recommended while using the matches.
