Senses Experiment

Watch Sound Travel

Materials you will need: • Scissors • Plastic Bag • Elastic Band • Plastic Bottle • Tea-light Candle

Steps:

Make a drum from the plastic bottle:

1.  Cut the bottom end (base) from the plastic bottle.
2.  Cut a piece from the plastic bag to cover the bottom of the bottle.
3.  Stretch and fit the piece of plastic tightly over the end of the bottle.
4.  Place the elastic band over the plastic bag to secure it.
5.  Light the tea-light candle.
6.  Point the top end of the bottle to face the tea-light candle, about 2.5cm (1 in.) away from the candle.
7.  Tap the piece of plastic bag with your fingertips.

What happened to the flame?

Sound is invisible.  You can see and feel the way it makes the air vibrate as it travels.  When the piece of plastic is tapped, tiny particles in the air beside it vibrate.  These vibrations make the particles beside them vibrate as well.  The vibration travels through the bottle and the flame is blown out.
