    • From side-on, the cut should look like a crocodile’s jaw!

    • Fold the straw at 3 separate locations and nip one corner of the straw at each of these locations. This will create three nice diamond-shaped holes at these locations

    • Blow through the straw, with the cut end in your mouth, and you should produce a nice loud, constant sound!

    • Block the holes with your fingers and play the straw like a flute!

    • Blowing too hard

    • Blowing too slowly

    • Triangular baby crocodile’s mouth (reed) is too small

    • Not enough of the reed inside the mouth

    • The straw not flattened enough at the cut, i.e. the reeds are too far apart

    • If the diamond holes are too small such that no air escapes them, then no sound will be produced

    • If the diamond holes are too big such that you can’t block them with your finger(s), then you may not get the desired sound

    • Why does the sound stop when you blow too hard or too softly?

    • Measure the length of the straw

    • Hum the same note the straw makes; can you produce more than one note? If so, how many? If not, why not?

    • How many notes can you produce now?

    • What is the length of the straw at each of these holes?
