======Straw Reed Instrument====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Drinking Straw Oboe ====Summary==== {{$demo.summary}} ====Procedure==== - Take a thin plastic straw. - Flatten one end and cut it into a pointed tip, like an arrowhead. This forms the vibrating reed. - Place the pointed end in your mouth and blow. Adjust position until the straw vibrates and produces sound. - Shorten the straw by cutting pieces off the end while blowing. Notice the pitch gets higher as the straw gets shorter. - (Optional) Slide the cut straw into a larger bendy straw to create a trombone-like effect where pitch changes smoothly by sliding. ====Links==== How to Make a Music Instrument Using Only a Straw - Science World: {{youtube>41eakEpT-t8?}}\\ How to DIY Straw Reed Instrument - Baker STEM Lab: {{youtube>7U-q8rkvTHs?}}\\ 📄 Make a straw flute - Fizzics Education: [[https://www.fizzicseducation.com.au/150-science-experiments/light-sound-experiments/make-a-straw-flute/?srsltid=AfmBOorr0Sp7gGf7zOU0cYlcqZwNbfL1rPAgUEoKNWsh1n6yi8-0tnsP]]\\ ====Variations==== * Try using straws of different diameters to compare sound quality. * Test whether paper straws also work. * Join two straws together to create a longer instrument with a deeper pitch. * Experiment with blowing harder or softer to change tone. ====Safety Precautions==== * Use scissors carefully when cutting straws. * Do not share straws between students without cleaning. * Supervise young children to prevent swallowing small pieces. ====Questions to Consider==== * Why does shortening the straw raise the pitch? (It shortens the standing wave inside, increasing frequency.) * What do the pointed ends of the straw represent in a real instrument? (They act as a vibrating reed, like in a clarinet or saxophone.) * How does the diameter of the straw affect the sound? (Wider straws produce a lower pitch and sometimes a buzzier sound.) * What happens if you blow too hard? (The reed may jam shut, stopping vibration, or the pitch may squeak.)
