Hi Mother,

Try having a student run passed from a distance while they are turning a Sound Tube in the air.

Simple but also effective.

This should help.

Cheers,

Hello Mother,
we have used a 3-4 metre piece of rubber tubing which is whirled around the operators head. At one end is a Girl Guides whistle and the teacher/operator blows through his end.
Hope this helps,

Hi Mother,
We bought small cheap buzzers from Dick Smith, tied them to lengths of string and whirled them around.
Worked really well!
