Tear Gas

Tear gas, formally known as a lachrymatory agent or lachrymator (from lacrima meaning "tear" in Latin), is a possibly lethal chemical weapon that stimulates the corneal nerves in the eyes to cause tears, pain, and even blindness. Common lachrymators include OC, CS, CR, CN (phenacyl chloride), nonivamide, bromoacetone, xylyl bromide and syn-propanethial-S-oxide (from onions).

Famous quotes containing the words tear and/or gas:

    I saw a staring virgin stand
    Where holy Dionysus died,
    And tear the heart out of his side,
    And lay the heart upon her hand
    And bear that beating heart away;
    William Butler Yeats (1865–1939)

    ... when I awake in the middle of the night, since I knew not where I was, I did not even know at first who I was; I only had in the first simplicity the feeling of existing as it must quiver in an animal.... I spent one second above the centuries of civilization, and the confused glimpse of the gas lamps, then of the shirts with turned-down collars, recomposed, little by little, the original lines of my self.
    Marcel Proust (1871–1922)
