Lecture
This lecture presents a step-by-step tutorial on constructing a hovercraft using a propeller engine, cardboard, printed sheets, and a plastic bag. The instructor guides students through cutting, folding, and assembling the components to create the hovercraft. The lecture emphasizes the importance of following instructions carefully to ensure the hovercraft functions properly, creating an air cushion underneath. Students learn how to attach the propeller engine, secure the wires, and seal the plastic bag to trap air underneath. By understanding the airflow direction and proper assembly techniques, students can successfully build and operate the hovercraft on flat surfaces.
