musical instrument trash

By cutting the end of a straw you can create a reed instrument that you can actually play a tune on. You can also learn some things about the science of sound and music.

Also look at this video to make a reed based flute only with straws. Looks simple but you need to try this with your students.

Press fit a long plastic pen tube in a bottle lid. Press a hard straw on the rim for blowing. Stretch a torn balloon on the lid to make a taut membrane. Push the pen from below to touch the membrane. Now on blowing through the straw you will hear loud sound. The vibrating membrane will produce the sound.
