(West Palm Beach, Fla.)  Tricks and treats await brave “boils” and “ghouls” during the South Florida Science Center and Aquarium’s monthly “Nights at the Museum,” with this month’s Spooky Science theme.  Falling appropriately on Halloween night and beginning at 6 p.m., the evening will include a variety of scary science activities for kids of all ages.  Real mummies will also be on display, as part of the Science Center’s newest traveling exhibit, Afterlife: Tombs & Treasures of Ancient Egypt.
