The Difference Between High Explosives and Low Explosives

I never considered that high explosive was a technical term and that consequently there must be low explosives.

To quote Stephen Miller, the explosive expert from the video...

• Explosives are a mixture a fuel and an oxidizer.
• With low explosives these are roughly mixed together...when a low explosive reacts, it's a thermal reaction
• A high explosive is also a mixture of a fuel and an oxidizer...down on the molecular level, the atoms [?] of the materials are in such close proximity that they are linked together within the molecule and...they can react a whole lot faster...It's actually a shockwave reaction.

I didn't know those distinctions, and I really didn't know that high explosives can be safer for transportation because they're more stable, requiring a shockwave to set them off.
