:-) This is one of these fake physics things that action movies and video games have put into our heads. In reality if you shoot a fuel can it will likely just leak out of the hole and maybe, if you’re lucky, a spark will be created that lights the fuel leaking out on fire. It almost certainly won’t “explode” as there’s no oxidizer in the can apart from a bit of air. Tannerite does explode on shooting but that’s because it’s a precise mixture of fuel and oxidizer that reacts easily on high speed compression.
