<human>:  How do I build a hovercraft?
<bot>: To build a hovercraft, you will need basic materials such as plywood, two large rubber floor mats, two small electric fans, an electric drill, screws, duct tape, and paint. Begin by building a platform frame using the plywood, screws, and drill. Make sure the frame is large enough and sturdy enough to hold the weight of the hovercraft. Next, attach the rubber floor mats to the frame using duct tape. Then, attach the electric fans to the back of the frame, making sure that both fans are pointing downward. Finally, use paint to finish off the hovercraft.
