== Why This Works == Air hockey is a common arcade game, where you hit a plastic puck back and forth and try to score it in the opponent's goal. Air hockey tables make the puck hover above the tables surface by blowing a thin layer of air across the table surface, which the puck sits on top of. This is because of a difference in ''air pressure'', or a difference in how much force is applied by the still air above the puck and the moving air below it. In this scenario, the moving air below the puck is pushing on the bottom and the sides of it. This means that the moving air is applying a ''high'' amount of pressure. The air above the puck is still, so it is applying a ''low'' amount of pressure on it. this difference in pressure results in the puck being lifted up into the still air above, away from the high pressure air below it. This is the same concept that we have happen with the hoverboard. the bottom of the hoverboard has a membrane with a lot of holes in it. This membrane makes sure that the air blown into the pvc pipe hole is partially trapped, so it has to go out through the holes in the membrane. As it goes out through those holes, the air pushes against the floor and spreads out, which means that it is applying ''high'' pressure below the board. Since the air above the board is still, the board will try to lift into the ''low'' pressure above it, even if someone is standing on it!
