Water Bubbler System

Well, I Seen someone I know doing this so I'd figure I'd ask How and if my idea is simple enough or not...

The person had like a gallon size plastic bottle, filled with water, Bubbling,
His roots were straight to the water. He was using like... a Fish tank air bubbler thingy... I Got one too...

Now I was gonna do this... But is there anything I need to take into consideration before doing so?

Should the roots be constantly in the water? As long as it's bubbling and getting oxygen to it?

Will that work?

it should work for a small plant, but watch letting light into the water thats a nono.
