ACTION snaps of TNT are shot by these
two cameras, among the fastest in the
world. The rotating-mirror camera is ten
times faster than the earlier revolving-
drum model, although that was swift
enough to record the fastest explosive
known. Perfected by Dr. Robert W. Cairns,
director of the Hercules Powder Company's
experiment station, Wilmington, Del., both
cameras are used there to record detona-
tion waves traveling five to 25 times as fast
as sound. In a specially built explosion
chamber a charge in a glass tube is hung
near an opening facing the camera and
detonated by remote control. From the film
experts later study what has happened at
every instant of the explosion, even to one
ten-millionth of a second. This study of
the behavior of explosives is invaluable in
determining which is best for each job,
from coal mining to blowing up a ship.
