Human Body Sounds (Rhythm Drum)
★Exhibit Content: Human Body Conductivity ★Interaction: Electromechanical Interaction ★Operation: Press the start button, touch the ring, and listen to the sound. ★Exhibit Description: Through interesting electromechanical interaction, this exhibit allows visitors to learn about the science of human body conductivity through hands-on operation. The exhibit mainly consists of a display stand, grip rings, circuits, and a buzzer. Four grip rings are set on the tabletop, with built-in circuits connected to the buzzer. Visitors can hold the grip rings to connect their bodies to the internal circuit. When visitors clap each other's hands, the corresponding circuit is connected, and the buzzer sounds. ★Scientific Principle: The human body contains a large amount of blood, lymph, and cerebrospinal fluid. These body fluids are mainly composed of water, in which various electrolytes are dissolved, such as calcium, sodium, potassium, and other trace elements. These trace elements often exist in the form of charged ions in body fluids and move directionally to form an electric current. Therefore, the human body has conductivity and is prone to electric shock.
