Works Just like real hovercraft that goes on land, water, snow and ice!! It rides on a chion of air created by pressurized air blowing downward into the rubber air-bag skirt, specially designed to "seal" with the ground. Two powerful aircraft-style props provide propulsion and steering. Straightway hovercraft blasts over most any level surface flat and smooth enough to "keep the air in" floor, pavement, dirt, water, ice and snow!
