The Underwear Experiment: Unraveling the Hidden World of Soil A recent experiment in Switzerland has been making waves in the scientific community by using a rather unexpected tool to study soil decomposition – a pair of cotton underpants.
Researchers buried over 2,000 pairs of cotton underpants and 12,000 tea bags at various sites across Switzerland, observing how these materials break down in different soil types.
The "Underpants Index" offers a fascinating glimpse into the hidden world beneath our feet. By using fabric degradation as a visual indicator, participants could see firsthand how active their soil was.
