There have been more than four million visitors to the South Carolina State Museum since 1988.

And the facility is celebrating its 25th anniversary by holding a big birthday party on Saturday.

Not only will guests have the opportunity to decorate their own birthday cupcake, but there will be Halloween games, plus a costume contest and parade.

The name of the Museum's new shark replica will be unveiled, and you'll encounter Star Wars impersonators, the Wurst Wagon with its German food, and you'll also get a special glimpse of the Museum's construction project for its new digital dome planetarium, 4-D theater and observatory.

But Museum spokeswoman Anna Kate Twitty says that's not all.

We are reducing our general admission pricing,” Twitty told WVOC.  “It's going to be $2.50 for general admission, and then an additional $2.50 to see our blockbuster exhibit 'Tutankhamun: Return of the King,' which is popularly known as 'King Tut.'  So, for $5, people can see everything in the museum.  This is a great value.”

Plus, guests will receive 25% off their purchases at the Cotton Mill Exchange store, which features unique South Carolina gifts and items for the upcoming holidays.

The day-long birthday bash gets underway at 9 a.m. Saturday with those birthday cupcakes served at 4 in the afternoon.
