What does the simplest but at the same time very effective explosive consist of

The simplest and most effective explosive substances typically consist of a combination of a fuel and an oxidizer. One of the most common examples in amateur settings is a mixture of ammonium nitrate (as the oxidizer) and a fuel source, such as diesel fuel, which forms what is often referred to as ANFO (Ammonium Nitrate Fuel Oil). However, it’s important to note that discussing or attempting to create explosives is illegal and dangerous. Handling explosive materials requires specialized knowledge, training, and strict adherence to safety regulations. The production and use of explosives are heavily regulated in most countries due to the potential for misuse and catastrophic consequences. Always prioritize safety and legality in any discussion or inquiry related to explosives.
