Bring your Trick-or-Treat bag and get ready to grab gobs of goodies in our exhibit spaces as you concoct glowing slime and make creepy crafts! Fill in a bingo card as you garner science facts and feats from expired engineers and deceased scientists. Explore the Park in the dark, pick up a prize from Alfred Nobel, enjoy the not-quite-right chemistry of Dorothy Hodgkin, and practice science tricks that look like magic! Grownup ghouls, mid-sized monsters, and little goblins will have an enchanting experience in this non-scary Halloween festival of fun. Come in costume!
