You are making it hard on yourself by inserting the air tube into the "column" aquarium you've made from the water bottle. That defeats the whole vacuum principle which you counteract with your vacuum tube

As you surmised the water can be oxygenated in the shallow "aquarium" represented by the bowl. And no active vacuum is required. As long as the column is air tight the water will not fall out.

Water can also be oxygenated with a small water fall or any other "mixing" action.

RE: inserting the air tube into the "column" aquarium

This is done to allow bubbles to be blown into the water, more to add a Magic effect, (when other see, how do they do that), than anything else.

RE: As long as the column is air tight the water will not fall out.

As show near the end of this video, but no more bubbles allow,

@Films4You Oh I see. It would be a neat effect.

No for someone, (hint, hint), to use it a a water cooling method for a computer :)
