Tea Bag Index

Screenshot
The Tea Bag Index is a unique citizen science project that measures global tea bag decomposition. Participants have one simple task: take two plastic tea bags (one Lipton Green tea bag and one Lipton Rooibos tea bag) and bury them just 8 centimeters below the ground in a the same location (15 centimeters apart from one another). After 2-3 months, remove the tea bags, dry them out, weigh them, and submit the data to the Tea Bag Index team. What can the weight of these tea bags tell us? These weights indicate the rate of plant decay in a specific location. Plant decay rates are influenced by the amount of carbon in a particular location, offering information about the impact of greenhouse gasses in the local environment. Those interested in participating in this project should check out the detailed instructions on this website. Those simply curious about the project can check out the locations of current contributors on the Map, found within the Data tab, or read media coverage of the project via Publications.
