Thanks to a lady I call Mom, I was sent
this news article today from the Mpls. Star Tribune (normally I just rip on this rag they call a paper, but not today). Apparently the Science Museum of Minnesota has won the rights to host “Star Wars: Where Science Meets Imagination” next June!
I went to something similar to this a few years ago where they had the actual filming models of various ships: Star Destroyers, Millenium Falcon, X-Wings and TIE Fighters. I also saw the real Boba-Fett costume. This one though sounds to be much grander.
From the Star Trib article:
The 12,000-square-foot exhibit features more than 80 costumes, models, and props from all six Star Wars films, including Princess Leia’s famous white dress, Luke Skywalker’s landspeeder from episode IV, a full-size R2-D2, Han Solo’s rogue outfit, and a Yoda puppet.
Exhibit visitors will be able to climb aboard a full-size replica of the cockpit from Episode IV’s Millennium Falcon and “journey” to a land far away. Guests also can sit inside a real-world hovercraft similar to Saga’s landspeeders and step into a lab where they can build and program robots and engineer droids.
Apparently this tour has been going on for quite some time already and will have travelled through 8 US cities before heading overseas. Kicking off in Oregon over two years ago, it is actually nearing the end of its journey. Currently in Chicago until Decmeber, it has two more stops: Fort Worth Museum of Science & History, Fort Worth, TX, (February - April 2008) and the The Science Museum of Minnesota, St. Paul, MN, (June - October 2008).
Admission will be $17 for adults and $14.50 for ages 4 to 12 and 60 and older. Personally, climbing aboard The Falcon will be worth the price of admission alone
