You can make
a fun flute from a plastic drinking straw by following these instructions: 1.
Chew on one end of your drinking straw to flatten it. 2. Cut the end
into a pointed beak shape with scissors. Blow hard on the flat end of the
straw to make music. Experiment by cutting small pieces off of the end of the
straw, then making a sound after each piece is removed. The sound pitch becomes
higher and higher as your drinking straw flute gets shorter and shorter. Explanation:
The number of times an object vibrates in a set period of time is called the frequency
of sound. As the frequency increases, the pitch of the sound gets higher. Shortening
the length of the drinking straw makes it vibrate at a higher frequency. This
gives you a higher-pitched sound. |
