Straw Pan Flute

What You’ll Create

Musicians, warm up your lips! 🎶 Your little composers will cut straws to carefully measured lengths, arrange them from longest to shortest, and tape them together to create a genuine working pan flute. Blow across the tops and each straw produces a different musical note — shorter straws make higher sounds, longer straws make lower sounds. It’s a beautiful instrument that actually plays!

How to Set It Up

Step 1: Cut Your Straws

Take 6–8 straws and use scissors to cut them to different lengths. Start with a full-length straw, then cut each one about 1.5 cm shorter than the last. Line them up from longest to shortest to check they look like a staircase pattern. ⚠️ An adult should supervise cutting for younger children.

Step 2: Arrange and Tape Together

Line up all your straws in order from longest to shortest, with the tops all level (the bottoms will be staggered like steps). Lay a strip of tape across the top third of the straws, pressing it firmly so they’re all held together in a neat row. Flip over and add another strip of tape to the back for strength.

Step 3: Seal the Bottoms

Fold a small piece of tape over the bottom of each straw to seal it shut. This is important — sealed straws produce a much clearer, louder note than open ones! Press firmly to make sure no air can escape through the bottom. Add stickers to decorate your flute! 🎵

Step 4: Play Your Flute!

Hold the flute up to your mouth with the tops of the straws level with your lower lip. Blow gently across the top of each straw (not into it — across it, like blowing across a bottle). Each straw makes a different note! Try playing from left to right for a scale. Can you pick out a simple tune like “Mary Had a Little Lamb”? 🎼

Have fun!

• 🎵 Try to play “Twinkle Twinkle Little Star” by finding the right notes!
• 🔬 Experiment: what happens if you cut a straw even shorter? What about really long?
• 🎨 Make two flutes and play a duet with a friend or sibling!
• 💧 Try filling some straws with different levels of water to change the pitch!

Why It’s Amazing

• Sound Science: Children discover the direct relationship between tube length and pitch — a foundational concept in acoustics and physics. 🔬

• Measurement Skills: Cutting straws to precise lengths requires measuring and comparing — practical maths in action. 📏

• Pattern Recognition: Arranging straws in order from long to short reinforces sequencing and pattern skills. 📊

• Musical Development: Playing a tune requires listening, experimenting, and developing breath control — all musical fundamentals. 🎶

Pro Tips

For ages 3–5: Pre-cut the straws and let them help with taping and decorating. Show them how to blow across the top and celebrate every sound they make!

For ages 5–8: Let them measure and cut with supervision. Challenge them to arrange the straws in pitch order by testing each one. Can they play a three-note tune?

For ages 8–12: Introduce the maths — if the longest straw is 20 cm, the next should be about 18 cm, etc. Challenge them to tune their flute to a real musical scale by comparing with a piano or app. Explore why closed tubes sound different from open ones.

Secret Pro Move: Use paper straws instead of plastic — they produce a warmer, rounder tone. And if you flatten one end of each straw slightly before sealing, the notes ring even clearer! 🎶
