with the sulfenic acid to form propanethiol S-oxide gas,which is a
volatile gas that reaches our eyes.this volatile gas then reactst with
the water of the eyes.forming mild sulphuric acid;causing a burning
sensation in our eyes this burning sensation stimulates the tear glands
to secrete tear;-(;-( in order to dilute and remove the irritant.
