Need one large bubble every 17 seconds

I am confused as to what you are aiming for.

Physically, an air bubble will not be any shape other than a sphere, because for a given volume, it will have the smallest surface area.

There is no way to get "oblong" shaped bubbles.

Unless it is moving (friction) or suspended (gravity)? Think soap bubbles.
But practically, getting anything that does not look like a sphere to a naked eye ...

That was a joke

Although it appears not a very good one <hangs head>

I was hoping they have invented some little device that holds the air out then releases in one big bubble every once in a while versus mini bubbles like you get with a wand.

Alright, I had that coming :icon_bigg

But I still want one large bubble coming out of a feature

Does the jewelry box come in blue :fish:

what your thinking of would need to work on the same principle as
that oh so lovely bountiful treasure chest (or "DEc'OR Aquatique")
ROTFL!

anyways, know you. chest lid void fills with air. buoyancy lifts lid on a hinge
large air bubble spills out.

or you could just pinch the air hose .

What do you mean pinching the hose?

make a diy co2 and run the raw airline wherever you want the bubble, tinker with the recipe to get the timing down, probably start with only a fraction of the normal yeast amount

This won't be CO2 at this location. I set a large bubble up under a coral using the tinker method 20 years ago. I was kinda hoping the Chinese developed a .49 cent gizmo to make my life easy

Same piece of coral and I guess I'll be doing the same tinkering
