The term "impulse explosive" refers to a type of explosive that is characterized by its ability to deliver a short, sharp burst of energy. Some common synonyms for this term include "flash-bang," "incendiary," "blasting cap," and "detonator." Flash-bang devices are often used by law enforcement and military personnel as a means of disorienting or distracting potential threats. Incendiary explosives are designed to start fires and cause destruction, while blasting caps and detonators are used to trigger larger explosives. It's important to note that the use of explosives is heavily regulated and should only be handled by trained professionals.
