Inkjet Printer

Inkjet Printer

In this activity, learners investigate 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 small scales, and see an explosive demonstration of how ink is forced out of an ink cartridge. This is a fun way to talk about how phenomena like surface tension become more important at small scales. Safety note: the demonstration involves fire���use appropriate caution.
