THIS AUCTION IS FOR 1 PINK MUSICAL TUBE: colours available are: Pink, blue, green and yellow

And now the fun part...


These tubes are: 

• 74cm in length 

• produce musical overtones in Key of A . Notes range from: Low A, E, Hi A, C# 

• a frequency ratio of 3/2. 

That's as much of the musical science as I can tell you. 

As described by Paul Doherty Here's how it works: 


Hold one end in your hand.

Twirl the other end in a circle.

Listen to the sound made by the tube.

Vary the speed of the tube.

Notice that the pitch of the whirly jumps from one note to another and increases as the speed of the twirling is increased.

That is, high speed twirling creates high pitch notes.

*******************

Bonus stuff: 

This can be more than a musical toy. In the right hands and with enough imaginative perception, it can also be: 

AN ELEPHANT'S NOSE, 

A DRAGON'S TAIL, 

A MICROPHONE, 

A SNAKE, 

AND MAYBE EVEN A SCUBA TANK FOR DEEP SEA MAKE BELIEVE! 

ITS ONLY LIMIT IS YOUR OWN IMAGINATION!


I HAVE USED THESE TOYS AS AN INVALUABLE TOOL FOR WORKING WITH CHILDREN AND ADULTS IN CREATIVE MOVEMENT AND DANCE SESSIONS. I HAVE HUNDREDS OF PROPS AND THIS SIMPLE PIECE OF MAGIC NEVER FAILS TO ENTERTAIN. THERE IS NO OTHER TOY THAT IS SO EFFECTIVE AT SOUND MAKING EITHER BY SPINNING OR BY SPEAKING/SINGING INTO IT. (THIS IS ESPECIALLY GOOD WITH THE USE OF A MICROPHONE AND SPACEY EFFECTS). 

It even does all this and more while playing in the bath or pool! 

EVERY KID SHOULD OWN ONE OF THESE PIECES OF MUSICAL HISTORY AND SCIENCE OF SOUND.
