Additional Info

• ID Code: K5-01
• Purpose: Demonstration of a piezoelectric crystal.
• Description: A small piezoelectric crystal is housed in a chamber with a lever on top. Pushing down on the handle stresses the crystal, producing piezoelectric charge which makes a small spark across two nail tips (first photograph), or can be displayed on the electroscope, as seen using the setup in the second photograph. A video camera can be provided upon request to display the device in large classrooms.
