Gravity Wizards is a hands-on innovation hub based in Anchorage, Alaska, where science, creativity, and play collide. Founded by inventor and educator Gary Francis Stout, Gravity Wizards is dedicated to making STEM exciting, accessible, and unforgettable through imaginative experiences that blend engineering with fun.
As the home of the Gravity Powered Air Derbies Association (GPADA), we champion innovation through flight—building a culture where learning and laughter lift off together, Alaska-style.
A FOBB is Gravity Wizards' safe, rocket-inspired STEM airframe featuring a transparent slotted fuselage, customizable fins, tunable internal ball-bearing & coupling weights, and a mounted soft rubber nosecone engineered to bounce safely indoors or outdoors.
Think of a Pinewood Derby launched into three dimensions! Builders customize their FOBB's fin geometry and Center-of-Gravity ballast, then launch using pure gravity counterweight power (zero pyrotechnics or compressed gas). Every derby crowns Flight Wizards (height/distance), Bounce Wizards (softest or most creative bounce), and Art Wizards (visual design).
