Win a $750 CASH prize courtesy of Champion Party Supply! Come dressed in your horror best to the creepiest Halloween costume contest in town — MoPOP’s Fashionably Undead 9: An Experiment in Terror. Passionate polymaths who didn’t stop to think if they should and screwy scientists who refuse to let the sleeping dead lie take center stage this year as we explore evil scientists and experiments gone wrong.

Other prizes include weekend passes to Emerald City Comic Con, weekend passes to Crypticon, MoPOP tickets, gift certificates to Hourglass Escapes, and horror swag. Categories will include: Most Creative Costume, Scariest Costume, Best Couples/Group Costume, and Best Themed Costume (Evil Science). Full costume contest rules <link>

Explore the museum’s most haunted spaces with eerie photo ops, art installations, and access to our sci-fi, fantasy, and horror galleries. Dance your fears away surrounded by fellow freaks and find someone new in the crowd. Just make sure you don’t sign up for any unpaid studies…
