An elongated tubular container filled with a liquid explosive charge is provided with a detonator at one or both ends thereof to provide a linear explosion along the length of the tubular container. The tube may be buried in the ground by a tube burying plow, suspended by floats in water, laid on the ocean bottom, etc. for forming ditches, providing seimic sources, etc. By providing a small tube in a larger tube, a potential explosive liquid can be activated by an activator contained in the small tube, by removing the small tube from the large tube through squeezing rollers at one end of the large tube.
