Three Drops is a full body immersive simulation that allows visitors to interact with water at three size scales using their shadows. At each scale, different physical forces can be observed. At the macro (human) scale, where gravity is the noticeable force, visitors are showered with water drops from a simulated shower. At the microscale--one thousand times smaller--where surface tension becomes more apparent, visitors play with a beach-ball sized water drop.
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.
A formative evaluation was conducted on Three Drops, an Immersive Digital Interactive (IDI), that allows visitors to interact with simulations of water at different size scales where different physical forces dominate. This evaluation revisits the exhibit after changes were made to address issues identified in the first series of formatives.
