You’ll need

  • A sheet of paper
  • Scissors

Try this

  1. Cut out a piece of paper approximately 10cm long and 5cm wide.
  2. Fold the paper in half widthways so that you end up with a doubled-over piece 5cm square.
  3. Bend each of these halves back on themselves so that the paper has three creases. Unfold these halves so that you return to the 5cm by 5cm size.
  4. Cut two small triangles out of the paper at the middle fold.
  5. Bring the paper to your mouth so the sides rest against your face and the section with the holes points away from your face. Hold the paper in place by resting a finger on each side of your mouth.
  6. Blow into the piece of paper. What sort of noise do you hear?

What’s happening?

As air rushes through the two small holes, the paper begins to vibrate very quickly. This rapid vibration causes a high pitched screeching noise.
