A display where jumping on a board produced this whistling sound. Mr. X. gives it a go. We chose to visit the Franklin Institute in Philadelphia, PA on the last day of our spring break 2016 vacation. It was founded in 1824, the Franklin Institute is one of the oldest centers of science education and development in the United States. According to Wikipedia anyways.
