Spooky Science gets underway at 10:00 AM on Saturday, October 16, at the Kirby Science Discovery Center in the Washington Pavilion, downtown Sioux Falls, and the activities don't end until 5 PM. You can stay all day or just until you and the kids wear out!

Kids can show off their delightful or frightful Halloween costumes (adults can also strut their stuff in costume) while having all kinds of hands-on fun with Boo Bubbles, Squishy Slime, building blocks, life-size dinosaurs, and more!

Speaking of dinosaurs, Washington Pavilion mascot Radley Rex could stop by and let kids know just how interesting STEM (Science, Technology, Engineering & Math) subjects are!

The USD Center Brain and Behavior Research is bringing a wiggly, jiggly Jell-O brain, to explore. And for the first time at Spooky Science - - South Dakota Ghostbusters, paranormal investigators will be there with their equipment, and share stories about their adventures.

All the kids will get a bag of Halloween treats to bring home after their day of education, celebration, and exploration!
