Things You'll Need
Instructions
Remove both sets of trucks and wheels from the bottom of the old skateboard using the Phillips screw driver. Drill out a hole about 2 inches in diameter through each of the curved ends of the board.
Place the skateboard on top of the plywood board and trace the outline of the skateboard with the black permanent marker. Set the skateboard aside. Cut the skateboard shape out from the piece of plywood.
Lay the 1-inch foam insulation piece around the perimeter of the cut plywood board and cut the insulation piece to size. Glue the insulation in along the perimeter of the board. Use the handheld knife to cut the insulation on the ends of the board down to 1/2 inch width.
Drill out 15 to 20 evenly spaced holes around the perimeter of the plywood board inside the insulation border through the plywood and the pond sheeting. Each hole should be about 1 inch in diameter and the holes should all be about 1/4 inch from the insulation border.
Lay the truckless skateboard gently down on top of the insulation perimeter on the cut plywood so that the skateboard and the plywood are lined up, with the insulation in between. Then nail skateboard into the insulation along the perimeter. You should now have two boards sandwiching together a layer of insulation that is about 3/4 inch thick.
Tape over in the exposed insulation between the boards using the electrical tape. This layer of tape should be airtight, with no gaps anywhere along the board's perimeter.
Insert the exhaust ends of each of the blow dryers into the 2-inch holes on the ends of skateboard side and tape them into place using the electrical tape. The seal of the blow dryers into the holes should be airtight, with no gaps anywhere along the holes. Now the air from the blow dryers will blow into the gap between the boards.
Transport the board to an open space with a smooth surface, such as a basketball gym. Stand in the center of the board and turn both blow dryers on to the highest setting. You should begin moving, with the air blown from dryers into the gap between the board and coming out through the evenly-spaced bottom holes to create the layer of air on which you move.
