Materials

  • Fresh green coconut palm leaflet
  • Damp cloth

Steps

  1. Pick one long, fresh green leaflet
    Choose a leaflet from a fresh coconut frond that is green and flexible, about 50 to 60 cm long and not torn. If you have a whole frond, take one from the middle of the stalk, where leaflets are longest. Wipe off dust with a damp cloth. Common mistake: using a dry or yellow leaflet. It cracks when you roll it and will never make a sound.
    Tip: Pick the leaflet in the morning. Fresh ones are the most bendy.
  2. Split the leaflet and pull out the midrib
    Hold the thick end. With your thumbnail, split the leaflet along the thin midrib in the middle, then pull the midrib away down the whole length. You now have two flat strips, each about 1.5 cm wide. Use one strip and keep the other for a second try. Pull slowly so the strip does not tear.
  3. Fold the thick end into a tiny starter loop
    Hold the strip with the shiny side facing out. Bend the thick end into a small loop about the size of your pinky fingertip and pinch it between your thumb and finger. This loop is the narrow mouth end of the whistle, so keep it tight and neat. Common mistake: starting with a big loop, which makes a wide, noisy cone that will not whistle.
  4. Roll the strip around the loop in a tight spiral
    Keep your pinch and wind the rest of the strip around the loop, turning your wrist so each new turn sits next to the last with about 5 mm overlapping. The spiral will grow into a cone, narrow at the start and wider at the tail, like an ice-cream cone. Keep each turn snug. Common mistake: loose turns, which let air leak and kill the sound.
    Tip: Keep your pinching fingers still and turn the leaf with the other hand.
  5. Tuck the tail end to lock the cone
    When about 3 cm of the strip is left, fold the end under the last turn and push it in so it stays. If it keeps popping out, fold the end over once more and tuck it again. Hold the cone to the light. You should see overlapped turns and no gaps. A cone about 12 to 15 cm long is a good size for a first try.
  6. Flatten the narrow tip and blow gently
    Press the narrow end between your thumb and finger until it is flat, like a drinking straw squeezed flat. Put the flat end between your lips and blow gently, as if blowing out a small candle. You should hear a buzzing whistle. If it only hisses, press the tip a little flatter, or re-roll the cone tighter. Do not blow hard.
    Tip: Wet your lips a little. A damp tip vibrates better.
  7. Try shorter and longer cones to change the note
    Make a second whistle with a shorter cone, about 8 cm, for a higher sound, and a longer one, about 20 cm, for a lower sound. Practise until you can make 2 or 3 different notes. Leaf whistles last a few hours, then go limp, so put the leaf in a compost bin or garden when you are done. Supervise young children so they do not put pieces in their mouths.
