 A fast food duck call?

Use a plastic straw to make a duck call!

You will need:

  • One plastic straw from your kitchen or local fast food restaurant
  • Scissors
  • Lungs (don't worry you already have them)

What to do:

    1. Use your fingers to press on one end of the straw to flatten it - the flatter the better.

    2. Cut the flattened end of the straw into a point (see below).


    3. Flatten it out again real good.
    4. Now take a deep breath, put the pointed end of the straw in your mouth and blow hard into the straw. If all goes well you should hear a somewhat silly sound coming from the straw. The smaller you are, ther harder it may be to get a good sound - sometimes adults can get more of a sound thanks to their bigger lungs. If you still have trouble, try flattening it out some more.
    5. Don't stop there - try cutting the straw in half to see how the sound changes, or make another identical straw and add the ponted end of the new straw to the uncut end of the first straw (to make the first straw longer) The sound wil be very different, (more like a moose call!) and you will have to blow even harder, but give it a try.

This is science? It sure is. You see all sounds come from vibrations. That little triangle that you cut in the straw forced the two pieces of the point to VIBRATE very fast against each other when you blew through the straw. Those vibrations from your breath going through the straw created that strange duck-like sound that you heard. Now you will never be bored again when you go to a fast food restaurant! Have fun!
