Musical Chemical Detector
Researchers at the University of California, Riverside have discovered the chemical detection abilities of an African musical instrument called a mbira. The instrument uses metal times connected to a wooden sounding board which produce a musical tone when plucked. The research has discovered that using a hallow U-shaped tine filled with different liquids produce notes of different frequencies. These differences can be used to detect different liquid samples such as sodium chloride or non-toxic glycerol.
