The Franklin Institute Science Museum
An innovator in designing hands-on exhibits before “interactive” became a buzzword, the Franklin Institute is as clever as its namesake. Its eminently touchable attractions explore science in disciplines ranging from sports to space. Highlights include The Sports Challenge, which uses virtual-reality technology to illustrate the physics of sports; The Train Factory’s climb-aboard steam engine; Space Command’s simulated earth-orbit research station; a fully equipped weather station; and exhibits on electricity.
