snoozefestaudioThe big balloons finally came yesterday. Six of them. Black.
The openings were large, designed to have plastic plugs put in them. I didn't have plastic plugs, but I did have a bag of wood disks which were the right diameter.
So I was able to blow one up... put in the disk to keep it inflated for the test... then remove the disk and deflate it again.
I inflated it to about 2.5 feet wide, and hung it from one wind chime with a hook and twine outside, with the anemometer motionless. No wind.
And while it did have a perceptible swing, it wasn't enough to ring the chimes.
I tried with a very long string almost to the ground, and a very short string just clearing the keys. But string length didn't make a difference. The clapper moved about the same horizontal distance regardless.
So... a difinitive test. There is no practical sail big enough to ring the key chimes in the dead of summer, because the air really is... just too still.
