Minor Versionm

Introduction

A spiral is made alongwith the oboe to create a spinning "trunk" as you blow through the oboe

Tools

Parts

    • Handle the Scissor with care.

  1. Flatten the end of a straw and cut the end of the straw in a triangular shape of about 2cm From side-on, the cut should look like a crocodile’s jaw!

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

  2. Starting from the uncut end of the straw, place the scissor at an angle such that you cut the straw into a spiral using up about half the length of the straw Starting from the uncut end of the straw, place the scissor at an angle such that you cut the straw into a spiral using up about half the length of the straw
    • Starting from the uncut end of the straw, place the scissor at an angle such that you cut the straw into a spiral using up about half the length of the straw

    • Blow through the straw with the cut end in your mouth.

    • The spiral should spin around. Even better if you can get the whistling sound as well as the spinning spiral!

    • 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

    • It’s quite likely that when the straw makes a sound, the spiral doesn’t spin satisfactorily and vice-versa

    • 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?

    • Why do you think it is tricky to make both aspects of the toy work satisfactorily in unison?
