Abstract
Some of the most intriguing science museum exhibits start with a counterintuitive outcome: a result that runs counter to visitors' expectations. Although counterintuitive events often succeed in captivating visitors, they rarely lead to visitor-driven inquiry. I argue that this is primarily due to two factors. First, for the counterintuitive effect to be presented reliably and repeatedly, the visitor's interaction must be limited to a narrow set of options. Without multiple options for visitors to explore, extended inquiry is nearly impossible. Second, counterintuitive outcomes beg the question “why did the outcome occur?”. Answering such a “why” question through experimentation alone is too challenging for most visitors; they either leave the exhibit or turn to an explanatory label. In either case, the potential for inquiry is unrealized. Three strategies that both motivate visitor inquiry and allow for open-ended exhibit designs are presented: revealing beautiful aesthetics, supporting creativity, and providing engaging representations.
