The International Space Station has been plagued by a small leak for several months. It was first detected in September 2019 but not immediately addressed since there was no threat to the station or astronauts aboard it. This week, cosmonauts finally tracked down the link using a rather low-tech method. According to a report, the leak's location was pinpointed utilizing a tea bag. The report did not elaborate on how a tea bag assisted the cosmonauts in finding the leak.
