Star Wars Sounds with a Slinky works with vibration that makes the sound.
 
With just the slinky it doesn’t make much sound, but when we add a Styrofoam cup, it acts like a speaker and when you 
gently shake the cup from side to side. You should hear the sound effects that can be similar to those heard in Star Wars! 

Try bouncing the metal slinky up and down on the floor to get a sharper sound. Now using a combination wrench even adds more.

The original blaster sounds heard in the Star Wars were made by the artist Ben Burtt who repetitively hit the high tension wires of a radio mast with a wrench! These sound samples were then taken back to the studio to be eventually heard on the film’s soundtrack.

In the case of the metal slinky and the Styrofoam cup, you’re simply transferring vibrations up the slinky into the Styrofoam which also then vibrates. The metal slinky vibrates against foam and creates part of the buzz that you hear, with the rest of the sound being formed by the foam itself vibrating and the sounds echoing within the cup. the larger air space within the cup caused the sound to amplify.
