Abstract
IT has been shown that when liquid explosives such as nitroglycerine are initiated by impact, the explosion begins as a comparatively slow burning which spreads for a short distance from the point of initiation at a speed of c. 400 metres per second, and is then suddenly transformed into a faster propagation at c. 1,800 m./sec., which has the property of a detonation wave1,2,3. This two-stage propagation occurs when the initiation is caused by impact and compression of a small included bubble, or by sparking, and is observed with all the liquid explosives which have so far been investigated.
