Squirted star-san in balloon, squeezed out.
Poked hole once with pin completely through balloon.
That would be two small pin holes once inflated.
Package said balloon was 1 foot inflated.
Perfect size, some looked too small or big.
Fit tight over bottle neck, secured with rubber band to be safe.
Poured too much juice out.
Perfectly balanced pressure, enough to slightly inflate balloon.
About 1/2 inch of foam subsided, but can see movement inside bottle.
Now the wait.
