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.
