Halloween Sounds | Screaming Cup Science Experiment
You've never heard a sound quite like this from an ordinary cup!
You’ve never heard a sound quite like this coming out of an ordinary cup! It’s the perfect sound effect to carry door-to-door on your Trick or Treat adventure.
- Large plastic cup
- Piece of string (24")
- Violin rosin (optional)
The Screaming Cup Ghost Scream Sound Effect Instructions
•Poke a hole in the bottom of the cup, just large enough to thread the piece of string.
•Thread the string through the hole and then tie a knot or two at the end of the string to hold the string in place.
•Wet the string or coat the string with violin rosin.
•Hold the cup in one hand and then pinch the string between your thumb and forefinger. Squeeze tightly on the string as you slide your thumb and forefinger down the string. With practice and a little patience, the string will “stick and slide” between your fingers causing a “screaming” sound. Oh, you’ll know when you’ve got it down to a science!
How Does It Work
How Does It Work?
Sound is transmitted through the air by vibrations. As your fingers slide across the string, vibrations occur. The violin rosin makes the string stickier and increases the “stick and slide” effect. The vibrations caused by “stick and slide” cause the cup to vibrate, which results in the amplification of sound. In other words, the cup produces an incredibly scary shriek and a scary screaming sound effect that will give you a tingle down your spine. Try different-shaped cups and determine what this change does to the screaming sound produced.
