Introduction

Make a series of sound toys: a straw oboe, an ice-cream stick harmonica, and a balloon bugle to have oodles of fun with music!

Video Overview

    • Handle scissors and cutters or any sharp tool carefully.

    • Be careful not to insert the straw too far into your mouth.

  1. Take two straws: one straight and one bendable straw. Cut the straight straw into two pieces such that the smaller piece is 5 cm long. Keep the bendable straw aside as we will use it afterwards.

    • Cut the straight straw into two pieces such that the smaller piece is 5 cm long.

    • Keep the bendable straw aside as we will use it afterwards.

  2. Measure and make a mark approximately 2 cm away from one end of the 5-cm straw piece Now flatten the marked end of the straw piece and cut it in a triangular 'V' shape, like an arrowhead. When viewed from the side, the cut should look like a crocodile's jaw!

    • Now flatten the marked end of the straw piece and cut it in a triangular 'V' shape, like an arrowhead.

    • When viewed from the side, the cut should look like a crocodile's jaw!

  3. Do the same with the longer straw piece Do the same with the longer straw piece Do the same with the longer straw piece
    • Do the same with the longer straw piece

  4. Take the bendable straw and cut it below the bendable part. Take the longer piece, flatten the end of the straw and cut it in a triangular shape of about 2 cm, exactly like in Step 2.
    • Take the bendable straw and cut it below the bendable part.

    • Take the longer piece, flatten the end of the straw and cut it in a triangular shape of about 2 cm, exactly like in Step 2.

  5. Fold the bendable straw at 3 cm from the end of the `V' cut. Cut/nip one of the two corners to make a diamond-shaped hole. Note that, to have the holes on the "top" of the oboe rather than the "sides" you have to bend the straw in a way such that the `V' shape on the pipe is perpendicular to the line where you bend the straw. Make another hole 3 cm further up the straw from the previous hole.

    • Make another hole 3 cm further up the straw from the previous hole.

  6. Play the oboe by inserting the cut-end of the straw in your mouth and blowing steadily into it. Ensure that your lips are placed just ahead of where the reeds begin when you blow. Do not squeeze the straw with your lips. Also ensure the reeds are flattened and kept as close to each other when you blow through them. You may also attempt to play the oboe by placing the uncut end in your mouth, and sucking instead of blowing!

    • Ensure that your lips are placed just ahead of where the reeds begin when you blow. Do not squeeze the straw with your lips. Also ensure the reeds are flattened and kept as close to each other when you blow through them.

    • You may also attempt to play the oboe by placing the uncut end in your mouth, and sucking instead of blowing!

    • You have 3 separate oboes. Play with them individually first.

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

    • Now do the same with the multi-note oboe; block the holes with your fingers and play the straw like a flute!

    • You may now also try and play by placing 2, if not all 3, oboes in your mouth and playing them simultaneously.

    • The straw oboe may not produce any sound if:

    • You blow too hard or slow.

    • The triangular "crocodile’s jaw" (reed) is too small.

    • Not enough of the reed is inside your mouth.

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

  7. Oboe made using straws of different stiffness. A spiral is made along with the oboe to create a spinning "trunk" as you blow through the oboe. Oboe made with straws of different cross-sections.
    • Oboe made using straws of different stiffness.

    • A spiral is made along with the oboe to create a spinning "trunk" as you blow through the oboe.

    • Oboe made with straws of different cross-sections.

    • Oboe made with straws of varying length.

    • If you want to learn how to make these variations, please go to Sound - Oboe (Variations).

    • Be careful while handling scissors or other sharp tools.

    • Don't move lips along the edges of ice cream sticks while blowing.

  8. Take a sheet of paper and an ice cream stick. Trace the outline of the ice cream stick on the paper. Cut along  the outline to get an ice-cream-stick-sized piece of paper; this will act as your harmonica "reed".

  11. Take one ice cream stick and place a spacer at one end of it. Place the paper reed on the spacer and ensure that it aligns with the ice cream stick.
    • Take one ice cream stick and place a spacer at one end of it.

    • Place the paper reed on the spacer and ensure that it aligns with the ice cream stick.

    • Cut the spacer if it is broader than the ice cream stick.

  12. Place another spacer opposite to the end of first spacer on top of the paper reed. Place the second ice cream stick on the paper reed - spacer assembly. Secure the assembly with rubber bands at both ends.
    • Place another spacer opposite to the end of first spacer on top of the paper reed.

    • Place the second ice cream stick on the paper reed - spacer assembly.

    • Secure the assembly with rubber bands at both ends.

    • Ensure that the two ice cream sticks, the spacers and the paper reed are aligned before securing the rubber bands.

    • Hold the pair of sticks between your slips, at the middle, and blow through the gap between the sticks!

    • You may try with sucking in air too!

    • Do not press the sticks with your lips too hard while playing.

    • Ensure the width of the paper reed is the same as that of the ice cream sticks

    • Spacers too thin, thereby not leaving enough space for the paper reed to vibrate.

    • Putting too much pressure with the lips on the ice cream sticks would restrict the paper reed vibration.

    • Paper reed becoming wet while kept between the lips.

  13. Multi-layer harmonica with three layers of paper reeds. Metal harmonica: a copper reed is used instead of a paper reed. A wider harmonica is made using wider ice cream sticks.

  17. Put a rubber band to make sure the balloon doesn't come off from the pipe when stretched. Your bugle is ready!
    • Put a rubber band to make sure the balloon doesn't come off from the pipe when stretched.

    • Your bugle is ready!

  18. To play, hold the balloon where it is attached to the straw with a rubber band, and stretch it slowly. Hold the pipe collar upright. The level of straw should be below the mouth of the pipe collar. While stretching the balloon, make sure not to twist it. The stretched balloon should be flat near the pipe collar.

    • While stretching the balloon, make sure not to twist it. The stretched balloon should be flat near the pipe collar.

    • Blow through the straw and create a lovely trumpet-like sound

  19. Fix one of the 20 cm pipes to the PVC collar. Make sure the longer pipe is tightly fitting into the bugle.
    • Fix one of the 20 cm pipes to the PVC collar.

    • Make sure the longer pipe is tightly fitting into the bugle.

    • Now play the bugle and observe the change in sound, if any.

  20. Attach another pipe and observe the difference in sound produced. Use PVC collars to attach the extra pipes. Attach another pipe and observe the difference in sound produced. Use PVC collars to attach the extra pipes.
    • Attach another pipe and observe the difference in sound produced. Use PVC collars to attach the extra pipes.

  21. Join the last pipe and play. Join the last pipe and play.
    • Join the last pipe and play.

    • Sound is faint or flappy: the balloon is not properly stretched. Stretch adequately and in the correct position

    • Unable to blow through the straw:

    • 1) Balloon is twisted.

    • 2) Straw being pressed hard and hence blocking air flow.

    • 3) The pipe is blocked from the other end.

    • Stretched balloon membrane too flimsy: Balloon has a hole.

    • Sound is produced but is feeble in nature: The level of the straw through which you are blowing is not below the mouth of the PVC pipe.

  22. Make a balloon bugle using the upper half of a bottle. Make a simple vibrating membrane by just pinching and pulling the balloon while blowing through it.
