Apparatus and method for the diffusion of less dense matter into a body of liquid. A floatation module is positioned upon the surface of the body of liquid and a draft tube is attached to the module extending below the module with the top end of the draft tube being spaced apart from the lower surface of the module. A feed line coupled from a source of less dense matter, such as compressed air, extends through the draft tube to the bottom of the draft tube terminating in a diffuser. The insertion and diffusion of the air into the liquid in the draft tube results in a draft action moving the liquid upward through the draft tube until it is deflected outward beneath the floatation module on the underside of the module.
