Which type of explosive is often used in homemade devices like Molotov cocktails?

Low-order explosives are typically used in homemade devices like Molotov cocktails due to their relatively lower detonation velocity and pressure compared to high-order explosives. Molotov cocktails function through a combination of flammable liquid and an ignition source, creating a fire rather than a high-order explosion. This aligns with the typical characteristics of low-order explosives, which can produce less destructive force but still generate significant effects through fire and shrapnel.

High-order explosives, in contrast, are designed to produce a powerful shock wave and a significant blast, which is not characteristic of a Molotov cocktail's intended use. Conventional blasts refer to standard explosive devices that are designed for specific controlled demolitions or military applications, whereas vehicle-borne IEDs refer specifically to explosive devices that are transported in vehicles, typically more sophisticated than a homemade device like a Molotov cocktail. Each of these alternatives does not fit the basic, simple construction and function of a Molotov cocktail, making low-order explosives the appropriate answer.
