From the press release:
I hope they still have the interpretation carts (I'm not sure if they're a part of the exhibit or an extra the musuem created for themselves), but they were really neat. We had a little ion engine, a prosthetic arm visitors could 'try', and a magnetism station with diamagnetic material (and liquid nitrogen ). In any case, I'm looking forward to seeing this neat exhibit again.It will fill the Center’s original museum building with costumes, models and props from all six movies in the Star Wars saga, along with many interactive exhibits, hands-on displays and laboratories -- where guests can conduct their own scientific experiments on magnetic levitation and experience augmented virtual reality. Even a replica of the Millennium Falcon cockpit will be a part of the exhibit, where guests can experience a multimedia presentation about making the jump to lightspeed!
