Abstract
A vessel with means for aerating a liquid therein, and particularly a bait bucket for containing water and live bait and means for replenishing oxygen in the water. The vessel has an upper chamber for containing the liquid, with a vent comprising a small aperture at the bottom of this chamber for allowing the liquid to slowly drip downward into a second closed chamber containing air or other selected gas. As the liquid occupies more of the space in the second chamber, the pressure of the gas in the lower chamber increases until a small quantity of gas escapes through the orifice, forms gas bubbles and rises through the liquid in the upper chamber. This gas flow is intermittent and will continue for many hours.
