Summer Fun 2014 - Singing Tubes on the Vacuum Cleaner


Have you ever just held a singing tube up to the hose of your vacuum cleaner, while it was running?  It's more interesting than you might think.


We found ours only made noise if we held them straight out.  Adding more tubes increased the volume, but did not change the tone.  The tone could be changed, and played with by slightly tilting, or swirling one tube into another.


The inside of our vacuum hose is ribbed just like the sound tubes, except that the ribs are pressed closer together.  After a little experimenting, we realized our vacuum hose sings too, if it's stretched straight out.  Fortunately we almost never stretch it out that way while vacuuming, and even if we happened to, the little whistle it makes is very quiet, proving there's more science involved in our everyday chores, than we sometimes realize.

For more fun with sound tubes, or to find out what they are, you might want to check out our singing tube stomp rockets...


...or singing tube science experiments.


It's great to be a homeschooler.

You know, I haven't seen a singing tube in years. I will have to keep my eye out for one.

I have never even heard of singing tubes. I'll have to add them to my wishlist.

Oh those singing tubes...... They are so cool until your kids play with them for an hour straight and then you're not so keen on the noise from them.
