Shock tube detonator

A shock tube detonator, often referred to as a shock tube or safety fuse, is a type of non-electric detonator used in explosives and blasting operations. It consists of a small, flexible plastic tube filled with a reactive powder, typically made of a mixture of black powder or similar materials. When the tube is initiated, usually by a shock or flame at one end, a fast-moving wave of pressure is propagated through the tube, igniting explosives connected to the opposite end.
