The aim of this fun science fair project for kids is to conduct a simple experiment to understand how snoring works.
A sheet of wax paper.
A pair of scissors.
Cut out a 15 cm or 6 inch square piece of wax paper.
Hold the paper by the sides and bring it up to your lips.
Hum a tune and observe the sound.
When you hum a tune with the wax paper up against your lips, the wax paper starts vibrating. This creates a sound which is similar to the sound of snoring. Snoring is caused by vibration of soft tissues inside the mouth.
When you are sleeping, the hanging piece of skin at the top of the throat comes down because of gravity and blocks the airway a little. When you breathe, the air flow causes the soft tissue to vibrate like the wax paper in the experiment, thereby creating the characteristic snoring sound.
