11 things Hollywood made you believe that are actually untrue

It is incredibly difficult to break open a padlock with a handgun. With a smaller calibre gun, it’s near impossible to accomplish.

Chloroform won’t knock someone unconscious in a matter of seconds. In fact it takes 5 minutes of exposure to the substance, and the effects are very short-lived.

It’s impossible to pull the pin of a grenade with your teeth. All you’d be risking by doing so is a trip to the dentist.

Asteroid belts are not at all dense like we see in Star Wars. In reality, there are actually miles separating each asteroid.

A drowning person will never make a scene like we see in films. In fact, most of the time it’s quite difficult to spot someone drowning from the surface.

Wielding two pistols and managing to fire both simultaneously is difficult to perform. It takes years of practice to successfully do it.

Silencers are better described as suppressors. They do not silence the sound of a gunshot, but merely subdue it.

It’s not possible to hold a conversation during a freefall while parachuting. The force from the fall and the wind cause far too much noise for even the smallest verbal exchange.

In the films, tracing a call takes between 30 seconds to a minute. In reality, it takes much longer: almost an hour.

Someone’s heart has stopped? Don’t even bother with a defibrillator – it won’t do anything for a heart that’s not beating.

Contrary to what we see in CSI and Waking the Dead, crime scene investigators don’t really participate in the investigation. Their role is to collect evidence.
