Describe the function of a blasting cap.

The function of a blasting cap is fundamentally to serve as a device used to initiate an explosion of the main charge. Blasting caps are designed to create a reliable and controlled detonation, ensuring that the main explosive material is ignited effectively at the right moment. They contain sensitive materials that can be set off by an electric current or via a shock wave from a detonator, allowing for precision in timing and execution.

This is critical in various applications, including mining, demolition, and military operations, where accurate detonation is essential for safety and effectiveness. The significance of the blasting cap lies in its role as a bridge between a triggering mechanism and the bulk of explosive material, reliably ensuring that the explosive charge can be discharged safely and accurately when needed.
