The exhibit is designed around the principles and knowledge points of the floating and diving of the underwater glider Glider. Visitors can change the posture and internal structure of the Glider through a sliding rod and buttons to understand how it achieves underwater gliding motion. Click the physical button and slide the slider to link with the transparent underwater glider model Glider in the physical water tank, to absorb water, release water, and change attitude, thereby understanding the basic principles of glider diving and floating, and controlling the glider to swim up and down. The underwater glider Glider does not have a propeller, but instead changes buoyancy like an Argo buoy, and with the help of wings, converts ascent and descent into forward movement. Sinking gliding: Absorbing water reduces volume, increases density, and sinks. The water flowing through the wings generates forward lift, causing it to glide diagonally downwards. Float up gliding: Discharging oil/water increases the volume and reduces the density while floating up. The wings once again convert vertical buoyancy into forward power, causing it to glide diagonally upwards.
