A host of not-too-scary activities and shows highlight Halloween Science at the Institute! Take a fun ride in the Acheson Planetarium, experience our electrifying scientist, hear creepy stories, see a pumpkin hurled through the air from our massive trebuchet, take the bug eating challenge, indulge in ice cream made right before your eyes, and much more! Amid the Halloween decor at the Institute numerous experiments, make-and-take arts & crafts and activity stations await young and old alike. While you explore the haunted hallways, check out the newly opened Permian Monsters exhibit.
