What is film strip?

A film strip is a long, narrow strip of transparent plastic film that contains a series of still images arranged in sequential order. Each frame typically measures about 35mm in width and is projected onto a screen using a film projector.

Film strips were commonly used in educational settings, such as schools and libraries, to display visual information to a large audience. The images on the film strip can be photographs, illustrations, or text, depending on the intended content.

Film strips are typically stored in a plastic or cardboard holder to keep them organized and protected. They are threaded through a projector, which advances the film strip frame by frame to display the images on a screen.

With the advent of digital technology, film strips have largely been replaced by digital media formats such as PowerPoint presentations and videos. However, they still hold sentimental value for many people who remember using them in the past.
