This cart demo is about piezoelectricity - how some crystals produce electricity when you squeeze them. Visitors learn about the history of piezoelectricity, how it's used, and how it's applied in nanotechnology. They make electric sparks, handle models and listen to cheesy music.
In this activity, visitors watch as a crystal self-assembles instantly! During this activity visitors learn what crystals are and how they grow. They also discover that self-assembly is an important process for many naturally occurring systems.
