Frequently Asked Questions

What is a FOBB (Flying Object Built to Bounce)?+

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.

How does a Gravity Powered Air Derby work?+

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).

Which kit should a first-time builder or family start with?+

Start with the Wizard's Basic Combo Kit ($19.99, available in Clear, Blue, Pink, or Green). It includes your complete FOBB body, soft rubber nosecone, internal weights, fin stock, Wizard's Wrench, diamond shaping file, 180° protractor, and latching storage bin. Schools and clubs can add extra Bare Bone ($7.99) or Heavy Bone ($10.99) bodies so every student builds their own flyer.

How does Verified Direct Ordering & Inventory work right now?+

Each SKU and color bin currently displays our live 23-unit workshop allocation. Submitting your cart logs a verified order number immediately in GwCrm, reserves your units, and alerts gary@gravitywizards.com with your itemized invoice & shipping confirmation from Anchorage/Palmer, Alaska.

How can parents apply for a Free Build Kit or schools book an Air Derby?+

Parents and guardians can submit a brief Letter of Interest right on this page (or email gary@gravitywizards.com) for a Free Build Kit. Schools, homeschool co-ops, youth clubs, and senior centers can use the Schedule a Gravity Wizards Event form to book an indoor gymnasium or outdoor GPADA Air Derby.

About Founder Gary Francis Stout • People Are Paramount

“People Trump Products Every Day of the Week and Twice on Sunday”

Gravity Wizards is a hands-on innovation hub based in Anchorage & Palmer, Alaska, founded by inventor and educator Gary Francis Stout (who filmed Launcher 2.0 while teaching Terminal Radar in Oklahoma City and continues his work with the FAA in Anchorage). One day, Gary hopes to observe a Gravity Powered Air Derby on the Moon—a tribute to his father, who helped build the first computer to land on the lunar surface.
