calculate the pressure on the mini hovercraft experiments by using the formula by knowing the mass of large balloon is 20,49 gr with a force of 0,2045 N was counted after balloon filled by air. The surface area was 0.011304 m 2 so the obtained pressure was 18.09 Pa. Calculation of a small balloon pressure with a mass of 20.3 g calculated after the balloon is filled with air by the force of surface area 0.203 the N of the surface area 0,011304 m 2 then the pressure of Pa is 17.95. A simple mini hovercraft that used for physics learning media on the pressure principal explains the utilization of air pressure on the mini hovercraft. The making of this mini hovercraft as a learning media is aimed to show the concept of pressure. From the results of observation and analysis of the data, it was proved that air pressure generated can produce bigger lift than the mini hovercraft weight. The air flowing out from the balloon in the bottom caused the mini hovercraft to be pushed upward.
