Johann Georg Sulzer (1720-1779)
[Wikipedia] Taste of Electricity "Battery Tongue Test" |
|
| Johann Georg Sulzer tasted pieces of lead and silver together. He stated,
"a pungent sensation that reminds me of the taste of green vitriol
(Iron (II) sulfate, FeSO4-7H2O) when I placed my tongue between these metals."
Sulzer thought that the cause is a “vibratory motion” of the metal atoms,
which make some interactions with the nerves of the tongue. He had found
this phenomenon before Volta but did not connect the phenomenon with electricity. Johann Georg Sulzer Recherches sur l’origine des sentimens agréables et désagréables. Troisième partie.
