A method for levitation includes flowing a source gas through an orifice to produce a Venturi effect as the source gas exits an outlet, entraining a secondary gas comprising ambient air, creating a pressure decrease at a secondary inlet of the secondary gas, mixing the source gas and the secondary gas to form a tertiary gas mixture, with the tertiary gas mixture including the source gas and the secondary gas, and with the source gas and the secondary gas mixed in a flow conduit having a constricted section of decreasing diameter and increasing diameter, flowing the tertiary gas mixture through an outlet, creating a pressure increase at the outlet, and inducing levitation through creation of a pressure decrease at the secondary inlet of the secondary gas and a pressure increase at the outlet of the tertiary gas mixture.

A hovercraft assembly includes a vehicle that may be driven. A pair of propulsion units is provided and each of the propulsion units is coupled to the vehicle. Each of the propulsion units may urge air outwardly from the body. Thus, the vehicle may levitate with respect to support surface. Each of the propulsion units may direct the air in a selected direction with respect to the body. Thus, the propulsion units may urge the vehicle along the support surface in a selected direction. Each of the propulsion units is operationally coupled to the handlebars such that the handlebars control operational parameters of each of the propulsion units.
