Ghostly experiments, bubbling potions and hands-on scientific discoveries filled the Patrick Henry Recreation Center Oct. 17 as families gathered for Alexandria's 11th annual Spooky Mad Scientist Expo, a Halloween-themed celebration designed to make learning both exciting and a little eerie.

Children and parents explored interactive exhibits where science came alive through spooky demonstrations and creative activities. Young scientists tested mysterious chemical reactions that produced colorful "monster slime," examined creepy crawly insects under microscopes, and learned about the physics behind glowing jack-o'-lanterns and fog effects commonly seen during Halloween.

“This year’s Expo brought together 90 national and local organizations, including six universities, 100 student volunteers, and more than 130 tables featuring hands-on activities and interactive experiences,” said event founder Zohreh Khoshnamak. “Hundreds of people attended throughout the event, which featured a wide range of STEM experiences, from robotics, AI, space exploration and engineering to health sciences, chemistry and creative technology.”

The event transformed traditional science education into an engaging adventure. Participants were encouraged to ask questions, conduct experiments and discover the scientific principles behind many of the sights and sounds associated with the Halloween season.

Local educators, student volunteers and science enthusiasts staffed dozens of activity stations throughout the fair. Popular exhibits included a "Mad Scientist Laboratory," where students safely mixed solutions to create dramatic reactions, and a "Creature Features" station that explored the biology of bats, spiders and other animals often associated with spooky stories.

"It's a wonderful way to show children that science is everywhere," said one volunteer educator. "When learning is hands-on and fun, students become excited to explore the world around them."

The event included a proclamation recognizing Oct. 17 as Spooky Mad Science Expo Day, with Mayor Alyia Gaskins, Del. Kirk McPike, and City Council members participating in the presentation. Other distinguished attendees included School Board President John Chapman, Sheriff Sean Casey, and Colonel James Page. 

The event also highlighted science, technology, engineering and mathematics education through challenges and demonstrations that encouraged critical thinking and problem-solving. Young attendees built structures, tested engineering designs and participated in interactive games that combined scientific concepts with Halloween-themed fun.

Many children arrived in costume, adding to the festive atmosphere as they moved from exhibit to exhibit collecting science-themed treats and prizes.

The Spooky Mad Science Expo is presented by Chrysalis Development Group, a 501(c)(3) organization, in partnership with the City of Alexandria.

“What makes Spooky Science especially meaningful is the community that has grown around it over the years,” Khoshnamak said. “Scientists, educators, families, students, community organizations, universities, and industry partners come together to share their expertise and resources and help make STEM opportunities more accessible to young people.”
