Franklin Institute

The Franklin Institute is as clever as its namesake, an innovator in designing hands-on exhibits before “interactive” became a buzzword. 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.

Films assume grand proportions on the Tuttleman IMAX Theater’s 79-foot domed screen; galaxies are formed and deep space explored in North America’s second-oldest planetarium, which reopened in 2002, sporting the continent’s most advanced technology. Don’t miss the 3D Theater and the indoor SkyBike.
