Through hands-on activities, visitors learn how inkjet printers produce tiny, precise drops of ink. They examine printed paper with magnifying glasses, see a few demonstrations of how liquids behave differently at the small scale, and see an explosive demonstration of how ink is forced out of an ink cartridge.
This is a recording of a NISE Network online brown-bag conversation held in 2014. The focus of this brown-bag conversation is on the applications and scientific background behind the following NanoDays 2014 kit activities:
• Exploring Properties - Electric Squeeze
• Exploring Properties - Capillary Action
Presented by: Lizzie Hager-Barnard of the Lawrence Hall of Science
For more information, and for a link to the recording, please see the Resources section of this page.
"Exploring Properties - Capillary Action" is a hands on activity in which visitors explore how liquids flow in narrow spaces. Visitors investigate how this behavior allows liquids to flow against gravity and soak into coffee filters.
