ELI5: Explain Like I'm 5

16 mm film

Imagine that you have a big book that has a lot of pictures in it. These pictures are like movies, but instead of moving on a screen, someone has to flip the pages to make them move. That's how old movies used to work!

Now, if you take each of these pictures and put them on a little strip of plastic, you can make a movie that moves all by itself. These strips are called film. But not all films are the same! Some are bigger, some are smaller, and they all work a little differently.

A 16 mm film strip is a special kind of film that is 16 millimeters wide (that's like one pinky finger). It's bigger than some other films, but smaller than others. This size of film is often used for making movies or short films, especially in the past before digital cameras were invented.

To watch a 16 mm film, you need a special projector. It's like a big machine that shines a light through the film strip, which makes the pictures on it move on a big screen for everyone to see. It's like a fancy movie machine!

Today, most movies are made with digital cameras and are shown in theaters using digital projectors that do not require any film at all. But people still love 16 mm films for their old-timey charm, and sometimes they're still used today for special events or artistic purposes.
