Building off of imagination and creativity, what people think UFOs look like are influenced by the movies and TV shows we watch, or the books and comics we read. This vision of what UFOs look like in popular culture has changed over time, and so have sounds!
When it comes to what UFOs may sound like, science fiction film and television composers usually use unconventional sounds that do not fit with what the human ear is used to hearing. They utilize instruments like the Theremin, an electronic instrument that is played by a person placing their hand at different levels within a field. It produces an eerie, warbling sound.
In this activity, create a UFO shaker to create the visual and sound effects of your very own UFO!
This is the model of the alien Mother Ship used in the filming of the movie "Close Encounters of the Third Kind" (Columbia Pictures, 1977).
