It's a Spooky Halloween at Science Center All month long Oct. 4-31 Alter your perceptions all month long as the St. Louis Science Center, 5050 Oakland Ave., is decorated for a "spooky" Halloween, Oct. 4-31, 2003. Fun activities, demonstrations and take-home items provide entertainment for the whole family. Walk through the scary "maze of illusion" and touch "gooey" items. Walk up to the infinity mirror, but watch out for the mummies and spiders hanging around every corner. Get dizzy as you stare into "spinning wheels" and see the giant spider hanging in the main lobby. Walk into the "black hole" while being "followed" by eyes in spooky drawings. In addition, come trick-or-treat at the Science Center Sat., Oct. 25, and includes lots of extra activities. Make "boo"-loon hats, enjoy face painting and more. All guests are encouraged to wear costumes, but it is not required. All activities and trick-or-treating are free.
