How to build a hoverboard?
To build a hoverboard, start by cutting a 48 inch diameter disk out of plywood. Cut a hole in the center of the board just large enough to fit the head of a leaf blower into. Next place the disk on top of a 6′ by 6′ sheet of plastic, then fold the edges of the plastic over the board, staple about 4 inches apart, and seal the edges with duct tape. Turn the contraption over and screw a coffee can lid to the center of the bottom of the board, then cut 6 vent holes around the edges of the lid. Turn your hoverboard back upright, insert your leaf blower into the hole and turn it on to fill the plastic bottom with air to float your board.
