Welcome to the most electrifying STEM celebration in the region, where science gets spooky, experiments glow, and imagination runs wild.

Now in its 10th year, the Spooky Mad Science Expo brings together hundreds of curious minds for an afternoon of hands-on discovery, eerie tech, and Halloween-inspired science. Past expos have featured incredible partners like NASA, NSF, USPTO, Boeing, and Titan Robotics, and while this year’s lineup is still bubbling in the lab, we’re cooking up a full-scale spectacle you won’t want to miss.
