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.
National Chemistry Week is the annual community event of the American Chemical Society (ACS). This year's National Chemistry Week theme is "The Sweet Side of Chemistry - Candy", showcasing the chemistry involved in candy and confections. In this online brown-bag conversation, presenters introduced National Chemistry Week, shared NISE Net activities that have a candy connection, demonstrated how to make edible gummy capsules, and explained the chemistry behind these sweet activities.
This is a recording of a NISE Network online brown-bag conversation held in 2014, which focuses 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.
