Straw Oboes

Friday, November 2oth, 2009
We found out today how to make straws into musical instruments. We squeezed the top of the straw, then teacher cut the top in the shape of a pencil top (or mountain). We could get the straw to sing by holding it between our lips and blowing. Teacher has a slide whistle. We could see that a short whistle makes a high sound, while a long whistle makes a low sound. With our straws the long straw makes a low sound. We can cut it while we blow, and listen to the sound getting higher and higher as the straw gets shorter and shorter.
