We all knew already that shooting into the gas tank of a car will not, in most cases, make it explode. Or at least, I had a vague notion about that, and confirmed it after doing a lot of research (five minutes on Google, maybe ten).
Incidentally, if you mention this on Facebook, a perhaps surprising number of people will tell you how to make a car explode by shooting it. Although that might be helpful knowledge under somewhat unusual circumstances, it’s not helpful if your protagonist just has a normal gun and a normal car, rather than a really impressive gun or a car that has a lot of explosives in the back seat.
Well, here’s something else that the movies shows us that doesn’t work in real life: Bystander cricothyrotomy with ballpoint pen: a fresh cadaveric feasibility study.
Hopefully it will never be important for you to know that those scenes where someone performs an emergency tracheostomy with a ballpoint pen are not based on reality.
