Through the "Fidgets for Fire Fighters" project, Fayette County students in grades 3 through 12 turned classroom STEM concepts into real-world crisis support. Students conducted biometric research—tracking their own heart rates under stress—to engineer tactile fidget devices optimized for calming individuals during emergencies. Using district 3D printers and filament generously sponsored by Bullard, students manufactured 1,000 custom devices for Lexington Fire Department engines, blending hands-on manufacturing, biometric data analysis, and compassionate community service.
