Light Gas Gun
The light-gas gun is an apparatus for physics experiments, a highly specialized gun designed to generate very high velocities. It is usually used to study high speed impact phenomena (hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids. Some basic materials research relies on projectile impact to create high pressure: such systems are capable of forcing liquid hydrogen into a metallic state.

Famous quotes containing the words light, gas and/or gun:
“Through the din and desultoriness of noon, even in the most Oriental city, is seen the fresh and primitive and savage nature, in which Scythians and Ethiopians and Indians dwell. What is echo, what are light and shade, day and night, ocean and stars, earthquake and eclipse, there? The works of man are everywhere swallowed up in the immensity of nature. The AEgean Sea is but Lake Huron still to the Indian.”
—Henry David Thoreau (1817–1862)
“Droning a drowsy syncopated tune,
Rocking back and forth to a mellow croon,
I heard a Negro play.
Down on Lenox Avenue the other night
By the pale dull pallor of an old gas light”
—Langston Hughes (1902–1967)
“Every gun that is made, every warship launched, every rocket fired, signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. The world in arms is not spending money alone. It is spending the sweat of its labourers, the genius of its scientists, the hopes of its children.”
—Dwight D. Eisenhower (1890–1969)
