The science behind this simple musical instrument, including the concepts of sound, vibration, and amplification.

00:00:39
An introduction to the cuica (pronounced KWEE-kah), a small friction drum used in Brazil's Carnival parade.

00:06:39
A detailed demonstration of how to make this small friction drum, including a discussion of materials needed and how different kinds of materials make for cuicas that produce different sounds.

00:01:30
The science behind this musical instrument, including the concepts of sound, vibration, resonance, and amplification.

00:00:24

00:02:32
A detailed demonstration of how to make this primitive wind instrument using little more than a straw, two craft sticks, and some rubber bands.

00:01:48
The science behind this instrument, including a discussion of how vibration produces sound, and how long, massive objects vibrate slowly and produce a low-pitched sound, while shorter, less massive objects vibrate quickly and produce a high-pitched sound.

00:01:15
An introduction to an instrument much like a saxophone but made of a water bottle and a paper tube.
