Launch a Paper Airplane
★Exhibit Content: Bernoulli, friction ★Interaction: Electromechanical interaction ★Operation: Children can make various paper airplanes according to their imagination, and follow the instructions on the graphic board. Place the made airplane in the middle of the clamp, adjust the direction, press the start button, and watch the airplane being launched quickly. ★Exhibit Description: The exhibit consists of paper, targets, fences, launcher, console, etc. The launch pad is a movable mechanism, and visitors can adjust the launch direction. During interaction, visitors fold different shapes of paper airplanes according to the tutorial on the graphic board, insert them into the ejection device, and then press the "Launch" button. The paper airplane is ejected, and they watch whether it can pass through the target hole. Try multiple times to see which paper airplane flies highest, farthest, and most accurately? Observe the shape and folding method of this paper airplane, and think about why it can fly highest/farthest/most accurately? ★Scientific Principle: The flight principle of paper airplanes is based on aerodynamics, especially Bernoulli's principle. The shape of the wings affects the airflow speed, thereby generating lift, enabling the paper airplane to fly. By adjusting parameters such as the center of gravity and wing curvature of the paper airplane, visitors can intuitively understand the role of aerodynamics in flight.
